The invention relates to the field of small, decentralized power and can be used for power supply facilities with stand-alone power plants, such as marine vessels, marine infrastructure, agriculture and forestry, mining, onshore fish processing plants and other

There is a method of automated control of synchronous diesel generator (SDG)with turbo boost (TKN) free (clean) turbo, cooler, charge air system run by compressed air, independent power Autonomous electric and hung produced pumps, an independent circulation pump fresh water cooling system, oil - and water heaters, fuel injection system on the basis of the fuel high-pressure pumps (pump), single-pulse mekhanogidravlicheskijj regulator fuel supply with built-in servo motor and a stop device (known as a centrifugal Governor angular velocity - CRF), generator circuit breaker, automatic excitation regulator (ARVs), device bias and precise timing, as well as sensors operating parameters of the diesel engine and the generator, namely, that in the "on duty" diesel generator (another "hot the reserve, "stand by") is heated lubricating oil and cooling fresh water due to the periodic transmission of steam through the oil - and water heaters, periodically pumped lubrication system diesel independent Autonomous electric power produced by the pump (EMPN) and the cooling system independent circulation pump fresh water, when you receive the command to start the back-SDG advanced pump diesel through independent power Autonomous ANN and drain the system and start the diesel cylinder from moisture, increasing oil pressure to the specified values crank the crankshaft of the diesel engine with compressed air, then produce two to three business start diesel with pauses between them by supplying compressed air into its cylinders and then to the turbine TKN, when increasing the angular speed of the diesel engine to the preset value (ωminautomatically inject into its cylinders fuel through the CRF and pump, then dispersed diesel fuel and compressed air to set intermediate values of the angular velocity ω1, then perform the following steps: cut system starting air shut off independent power Autonomous ANN, switch lubrication system hung on oil Sipper pump (NNN) and podmagnichivaniem cu is tauramena synchronous generator through the device bias, then dispersed diesel fuel by means of the servo motor CRF and smoothboard generator through its ARV, when increasing the angular velocity of the machine to posingangela values of ωPSand the generator voltage up to 85% of the nominal make time delay (to the operating parameters of the diesel engine has become the norm), then execute the subroutine exact synchronization of the generator, upon completion of which include synchronous generator in the network by the generator breaker, then automatically equalize due to ARV relative reactive load generators Q1and Q2and manually affect the servo motor CRF and equalize the relative active load diesel generators P1and P2(or translate it fully back on SDG in the case of replacement units). In the latter case, reduction of the resistive load on the output unit up to 5% of the nominal it is disconnected from the network by the generator breaker and reduce the angular velocity is off SDG to the established value, operate at this reduced speed within the prescribed time, then stop the supply of fuel through the stop device CRF. In parallel operation of synchronous diesel generators active load P1and R2keep evenly distributed (relative to the positive units) due to the actions of their CRF, regulatory speed characteristics are pre-set at the same statism (uneven regulation). (Baranov, A.P. Shipboard automated power system: the Textbook for high schools. - M.: Transport, 1988. - 328 S.).

Know of any other way to control diesel automatic electric unit with turbocharger boost (TKN) and a throttling element at the entrance of its compressor and running on an external variable load at a constant speed, namely, that after the launch and initial operations measure the load of the electric generator and regulate diesel by changing the fuel and air excess factor partial load to idle inclusive by air throttling element at the input of the compressor TKN, during startup, the load and the maximum load position of the air throttling element is left unchanged, and when stopping, and emergency protection throttling element completely close the compressor inlet TKN, and stabilization of the excess air coefficient is performed with the parameters of ambient air using a correcting effect on the position of the throttle element (RF patent for the invention №2200861).

The advantage of the first Izv the STN method of automated control of synchronous diesel generator is the possibility of automation, for example, a vessel on the sign of A2 (in the symbol of class of Russian Maritime Register of shipping), which can, in turn, reduce the number of watch keeping service in the engine compartment to one person.

The disadvantage of the first known method of automated control of synchronous diesel generator is, firstly, the significant duration of input SDG to work up to 30 or more, secondly, a bad pickup load them due to the free turbo (characterized by the lag of the air supply from the fuel supply due to the inertia of a system of free turbo), increasing the time of shifting load from one machine to another (which is important for emergency output from the defective unit and degrade the dynamic performance of generator units during surge/load shedding, third, poor economic and environmental performance in SDG transient modes and static modes partial loads, fourth, high hit probability hydrocarbon mixture in posovszky the pipeline (due to the mixed supply of starting air and fuel into the cylinders of the diesel engine during acceleration of the diesel engine from ωminto ω1mixed method run) with its subsequent explosion (detonation) in subsequent cycles of compression.

The advantage of the second is th known way to control diesel automatic electric unit is the regulation of diesel in the partial load modes of the unit until the idling impact simultaneously on fuel and the air excess factor adjusted last in the function of changing parameters of atmospheric air, which improves environmental performance SDG partial modes.

A second disadvantage of the known method of controlling diesel automatic electric unit is, first, economiccost method of regulation of the air excess factor by throttling the inlet air duct, a second, separate regulation of toplivopodachi and air pressure makes a consistent change in the mixture ratio of fuel-to-air, especially in transient conditions, thirdly, the throttle control is inertial, reduce the system performance regulation of air supply and does not completely exclude the smoky exhaust with a sharp surge load, fourth, stop diesel overlapping of the air duct at the inlet of the turbocharger causes instant stop him, while TKN continues to rotate a few minutes by inertia without oil pressure in the bearings, and the resulting output of the turbocharger vacuum causes the surge, accompanied by strong vibration TKN. Both the known method does not solve the problem of reducing startup time SDG.

The closest and known to the claimed method is automatically what about the management SDG third type TB/V "Grand Aniva", equipped with two turbochargers boost (TKN) free (clean) turbocharged and air valves on suction paths, cooler, charge air system starting with a pneumatic starter motor (pneumatical starter) and blowdown valve, independent power Autonomous electric and hung produced pumps, independent electrically driven circulating pump fresh water cooling system low temperature loop, hung circulation pump fresh water cooling system high-temperature circuit, oil and water heat exchangers, elektroobogrevatelem, built-in enclosure water heat exchanger, fuel injection system on the basis of the fuel high-pressure pumps (pump), single-pulse mekhanogidravlicheskijj regulator fuel injection (CRF) with built-in servo motor and the stop device, generator circuit breaker, automatic field controller (ARV), device bias and precise timing, as well as sensors operating parameters of the diesel engine and the generator and subsystem remote automated control - DOW (the Standard documentation for the LNG carrier "Grand Aniva", JSC "Sovcomflot": YANMAR Marine auxiliary engine 6EY26L (Operation manual). - YANMAR CO., LTD., Japan. - P.472-473), namely, that in the "de is to become" diesel generator ("hot standby", "stand by") on signal program subsystem DAU heated cooling fresh water due to the periodic switching on an electric heater, built-in water exchanger, pumps the heated fresh water independent electric circulation pump fresh water cooling circuit through thermostat fresh water, diesel and oil heat exchanger, fueling while the lubricating oil is intermittently pumped lubrication system of diesel engine with its thermostat independent power Autonomous electric oil Sipper pump, when receiving a command to run "on duty" SDG, including under increasing loads on start generator unit up to 80% of nominal, additionally pumped by diesel independent power Autonomous ANN and blow posovszky piping and cylinders diesel from condensation, increasing oil pressure to pre-specified values and the respective test crank the crankshaft of the diesel engine by pnevmostartery under reduced pressure, after which produce two to three business start diesel with pauses between them, at the expense of pnevmostartery when normal air pressure, with the increase in angular speed to a set value (ωminautomatically injected into the cylinders of diesel the fuel through its optical mekhanogidravlicheskijj CRF and injection pump and dispersed simultaneously diesel fuel and pneumatical starter to set intermediate values of the angular velocity ω 1, then perform the following steps: turn off the system starting air, switch lubrication system for hinged produced pump (NNN), turn off independent power Autonomous ANN, switch to a high temperature cooling circuit fresh water hung on the circulation pump and podmagnichivaniem short synchronous generator through the device bias, and then dispersed diesel fuel through optical mekhanogidravlicheskijj CRF and smoothboard generator through its ARV, when increasing the angular velocity of the machine to posingangela values of ωPSand the generator voltage up to 85% of the nominal make time delay (to the operating parameters of the diesel engine has become the norm), then do the exact synchronization of the generator, upon completion of which include synchronous generator in the network by the generator breaker, then automatically equalize due to ARV relative reactive load synchronous generators Q1and Q2and manually affect the servo motor CRF and equalize the relative resistive load R1and R2synchronous diesel generators or translate it fully manually to the backup SDG in the case of replacement units. In the latter case, reduce the drop of the resistive load on the output unit up to 5% rated it disconnect automatically from the network by the generator breaker and reduce the angular velocity due to the servo motor to podsyhanii speed ω PSwork at this speed for a set time, and then stop the flow of fuel through the stop device monopulse mekhanogidravlicheskijj CRF. When the parallel operation of diesel generators active load P1and P2keep evenly distributed (in relative units) due to the actions of their optical mekhanogidravlicheskijj CRF, regulatory speed characteristics are pre-set at the same statism (uneven regulation). When entering from one of the sensors is critical fault signal, for example, when the spacing diesel, off by subsystem DAU defective SDG without prior discharge its generator breaker and stop without delay by diesel stop-optical device mekhanogidravlicheskijj CRF, while blocking routine run, and if the angular velocity of 60 seconds will not be below ωmininclude alarm system stop and block the suction paths compressors TKN due to the damper.

The advantage of this known method of automated control of SDG is, firstly, more efficient flow of air when run SDG as pneumatic starter consumes less energy to run compared to t adicionam, cylinder method start with compressed air. Secondly, the starter system is somewhat simpler and more compact and therefore less spending and more reliable. Slightly reduces the acceleration of the diesel engine of this system in the first fuel-free period of time up to ωmin. Also completely excludes the ingress of hydrocarbons in posovszky the pipeline during the period of mixed dispersal from SDG ωminto ω1.

The disadvantage of this method is more time-delay overclocking TKN during run back LDH compared with the first analogue. The consequence of this is greater than the second analog mismatch-pressure charge air pressure fuel injection during the whole process of entering SDG in work due to low coefficient of excess air in the compression chambers. This increases the probability of a run with the first and even the second attempt due to newsplease the first portions of the enriched fuel mixture in the initial period of injection and falling for this reason, unburned hydrocarbons in the exhaust manifold ignition (detonation) from their exhausts the hot exhaust gases in the following cycles. A slight reduction in the total duration of the run through pnevmostartery (in the case of a successful first attempt) is not significant. This is especially for the maintain when entering SDG for parallel operation. Used exact matching method of operating conditions input SDG and running synchronous generator, called exact synchronization, requires for its implementation a few tens of seconds or even minutes. Therefore, the gain in reducing the time of starting the diesel engine by pneumatical starter and inclusion in the network "eaten up" significantly longer procedure required timing generator before turning on. By the way, this disadvantage is shared by all known methods, as well as the fact that after each stop they have a diesel and it hung oil Sipper pump it TKN continues to rotate for a few minutes by inertia due to the stored flight mass kinetic energy, without oil pressure in the bearings, and emergency stop diesel overlapping of the air duct at the inlet of the turbocharger boost causes its output vacuum, followed by a strong surge. From the standpoint of shortening the overall length of the known starting SDG operation purge pustovojtenko pipeline and cylinder diesel from condensation and cranking its crankshaft after receipt of the command to run (and not in the period of "duty") is irrational, because it reduces the degree of readiness "on duty" SDG to start. Periodic pumping of the duty" SDG independent power Autonomous ANN and heated lubricating oil and cooling water require additional energy (i.e. uneconomical and, in addition, have a low efficiency, because the pre-pressure in the lubricating system of this SDG supported uneven (oscillatory). The above discrepancy pressure charge air pressure fuel injection is observed in periods of sharp surge and discharge a significant burden on working SDG, which causes poor pickup diesel and reduce the quality of the supply in the electricity network electricity. The shortcomings of the first analogue in part to poor economic and environmental performance of SDG in transient mode and static modes partial loads due to free turbo manifest themselves in the prototype. The lower coefficient of excess air typical of diesel engines with a free turbo in transient mode and static modes partial loads, causes intense caesaraea the combustion chambers of the diesel engine, it TKN and total exhaust tract, which increases fire risk and effort required to complete their masochistic. When the load of the diesel engine more than 50% of the nominal part of the exhaust gas is bypassed without recycling in the exhaust tract, because the performance of TKN becomes excessive. This reduces the efficiency of the unit and leads to premature burning in the exhaust line.

Technical the second task, which sent the invention is to remedy these shortcomings of the prototype method, namely, a significant reduction (2-6 times) the total duration of the input SDG in action, efficiency (degree of readiness diesel) and economy of operations in the "duty" of readiness, improving the reliability of running a diesel engine on the first try by increasing the probability of ignition of the first reinforced portions of the injected fuel and eliminate due to this detonation explosions during launch, increase efficiency and ecological operation of DG in static modes partial loads and transient conditions surge/load shedding, improved dynamic characteristics SDG turbo with a sharp vibration of the load, and hence the quality of electricity produced by them, increasing the efficiency of the SDG in the range of loads from 50% of the nominal and above, excluding cases of TKN free run without lubrication and Troubleshooting surging of the turbocharger in the manipulation of his air baffle, and reduced fire hazard and labor required for maintenance SDG and its auxiliary systems.

The goal of the project is achieved in that in the known method of automated control of synchronous diesel generators is a PR in maintenance mode "on duty" ready to start synchronous diesel generator is heated by diesel pumping heated fresh water through his zerobalance space and cooling thermostat fresh water and pumps the heated lubricating oil through the oil thermostat and oil system of diesel engine, and these operations are performed by the program signals subsystem remote automated control of "on duty" synchronous diesel generator, when receiving the starting command "on duty" synchronous diesel generator checks if the pressure of lubricating oil to the specified value, produce three business start diesel by filing for pneumatical starter inrush of air at normal pressure, alternating attempts to start pauses between them, increasing the angular speed of the diesel engine to the preset value ωminautomatically injected into the combustion chambers of the diesel fuel through optical mekhanogidravlicheskijj centrifugal regulator angular velocity and the fuel high-pressure pump and dispersed together on diesel fuel and pneumatical starter to set intermediate values of the angular velocity ω1at which time simultaneously off pneumatical starter and switch lubrication system on its hinged produced pump, then dispersed diesel fuel through its optical mekhanogidravlicheskijj centrifugal regulator angular velocity excited synchronous generator by automating the definition of the field controller, moreover, at the steady state angular velocity of the unit, equal podinkrasnim value ωPSmake a short exposure time, by entering operating parameters of the diesel engine to normal, when the voltage of the generator is equal to 85% of nominal and the corresponding angular speed diesel perform routine synchronization excited generator is running synchronous generator include synchronous generator to the grid by the generator breaker will automatically align through excitation regulator relative to the reactive load generators, as well as the relative active load diesel generators P1and P2by monopulse mekhanogidravlicheskijj centrifugal regulators angular velocity or translate active load fully entered synchronous diesel generator in case of replacement of units during the period of this change upon reduction of the active load on the output unit to the minimum allowable it is disconnected from the electrical network by the generator breaker, reduce the angular speed by the servo motor to podsinivanija values ofώpwith a,which is operated during at the set time, then stop the supply of fuel through the stop device monopulse mekhanogidravlicheskijj centrifugal regulator angular velocity, and when the parallel operation of diesel generators active load P1and P2support the specified distributed through the actions of their optical mekhanogidravlicheskijj centrifugal regulators angular velocity, the regulatory characteristics of which are respectively set, and, upon receipt of a running diesel generator critical alarm has been shut down by subsystem remote automated control without the prior unloading diesel generator generator switch, stop by diesel stop-optical device mekhanogidravlicheskijj centrifugal regulator angular velocity and block routine run, and if the angular velocity of 60 seconds will not be belowώmin,include alarm system stop and block sasawashi tract turbocharger boost through the damper, and the sudden disappearance of voltage in the mains pumping lubricating oil before starting unprepared diesel generators, the Torah shall be implemented by independent on nutrition Autonomous electric oil Sipper pump, in contrast, in the inventive mode support "on duty" ready to start command subsystem remote automated control of lubrication diesel "on duty" synchronous diesel-generator produce continuously heated oil through the oil system directly working synchronous diesel generator through its controlled shut-off and butterfly valves and pipelines, equipped her for this, however additionally produce periodic cranking its crankshaft through pnevmostartery on low pressure compressed air and periodic draining pustovojtenko pipeline and cylinder diesel from condensing moisture through the starting system of compressed air and blow-off valve, razvorujut generator through the device of the magnetic damping field and temperature of the pumped lubricating oil and fresh water through their thermostats produced in accordance with software-defined subsystem remote automated control values calculated it based on measurements of environmental parameters. However, in the event of absence of necessity in the production of the "duty" of one of the synchronous diesel generators in the current mode control is controlled shutoff valves on the oil system working synchronous diesel generator from all reserve units close. When you receive the command to run, including by increasing the working load of the generator set to the specified limit, in addition to checking the pressure in the lubrication system "on duty" diesel generator, test the temperature of the air in the engine compartment and the absence of excitation of the running generator, when the air temperature in the engine compartment less valid continuum the air cooler charge air its diesel by-pass valve and simultaneously with the first enable pnevmostartery at the normal operating pressure at the start of the unexcited synchronous diesel generator produce acceleration and its turbocharger boost through its reversible synchronous electric machine in the mode of a drive motor without interruption of its operation during a possible starter pauses in the air, at the same time, the rotational speed of the turbocharger boost is set such that the value of the coefficient of excess air in the combustion chambers are launching a diesel corresponded to starting the flow of injected enriched fuel-air mixture. After the transfer of diesel fuel close the bypass valve of the air cooler, using the air cooler charge air boost fuel and in the period of forced software overclocking unexcited Synchron the th diesel generator fuel from the angular velocity ώminto podsyhanii angular velocityώpwith aregulate and the excess air factor of the adaptive fuel mass injected by the synchronous change of the rotational speed of the turbocharger boost through its reversible synchronous electric machine and its static semiconductor Converter, controlled by signals sent to the control system static semiconductor transducer potentiometer monopulse mekhanogidravlicheskijj centrifugal regulator angular velocity, kinematically connected with the fuel rail, this centrifugal speed regulator. When the angular velocity of the rotor of the generator reaches podsinivanija values ofώpwith ain addition to the time delay for entering parameters of the diesel engine in the normal and commissioning routine "monitoring of operating parameters", increase the signal subsystem remote automated control of the angular velocity of the synchronous diesel generator to oversinging values ofώwith ami> with aby means of the servo motor optical mekhanogidravlicheskijj centrifugal regulator angular velocity, then perform routine self-synchronization of the generator is running synchronous diesel generator through the device of the reactor-condenser self-synchronization, after which connect the synchronous generator to the grid by the generator breaker. In the operating mode with increased static active load on a synchronous diesel generator as its reception and, accordingly, the continuous increase of the torque developed by the turbine of the turbocharger boost, torque electromagnetic torque reversible synchronous electric machine, operating the driving motor, adequately reduced by reducing the voltage of the static semiconductor transducer signal generated trichinosis electronic proportional-differential-integral (SOPS) regulator supply of fuel and air. When the static resistive load synchronous diesel generator above 50% of rated reversible synchronous electric machine is transferred to the generator mode by inverting the static semiconductor Converter on the sensor signal Holos is wow stroke of the machine, fixing the moment of its transition to the idle mode, in this case, electrical energy is reversible synchronous electric machine, produced in the generator mode, refer to the electrical network through the chain of her power. When the synchronous operation of the diesel generator in the range of static active loads less than 50% of the nominal and sudden surge of significant power is measured by trichinoscope e-SOPS-regulator fuel and air signals static and dynamic increment of this power, coherent and synchronous boost these signals, the supply of fuel and the pressure of the charge air by that act a static signal to the servo motor optical mekhanogidravlicheskijj centrifugal regulator angular velocity, and dynamic control system static semiconductor Converter, increasing the tension of the last and torque electromagnetic torque reversible synchronous electric machine, operating the driving motor. Moreover, when a sudden discharge of significant power in this range of static loads measured in the same trichinosis e-SOPS-regulator fuel and air signals static and dynamic reduction of this capacity, which consistently and synchronously deviceroot supply that is greater and the pressure charge air diesel by that affect them on a servo optical mekhanogidravlicheskijj centrifugal regulator angular velocity and control system static semiconductor Converter than reduce the tension of the last and torque electromagnetic torque reversible synchronous electric machine. When the synchronous operation of the diesel generator in the range of static active loads above 50% of the nominal and sudden surge of significant power is measured in the same way the signals static and dynamic increment of this power, coherent and synchronous boost these signals, the supply of fuel and the pressure of the charge air by the fact that the static signal affect the servo optical mekhanogidravlicheskijj centrifugal regulator angular velocity and increase the flow of fuel and dynamic control system static semiconductor Converter, lower than the current last and brake electromagnetic torque reversible synchronous electric machine working as a generator, and when a sudden discharge of significant power in this range static loads fuel and boost pressure diesel in the same way and by the same means, simultaneously and consistently deviceroot. In maintenance mode "on duty" willingness to pus is in and working mode of a diesel generator is measured by the respective temperature sensors, pressure and humidity, as well as the current load synchronous diesel generator is determined from the measured values, by means of its subsystems remote automated control of the calculated optimum temperature of the unit and form a new set value of the temperature of cooling water and oil, which are sent to the appropriate sets the input temperature of cooling water and lubricating oil and regulate these thermostats set values of temperature. The sheer number of running generators, the degree of loading and the nature of the distribution of the resistive load in parallel is determined by the criteria of control of synchronous diesel generators, which are set by switch control criteria for the power plant. When economic criteria control the number of running generators imposed at the rate of their load about 80% of the rated based on the best efficiency units, and with greater loading trigger signal trichinoscope electronic SOPS control the flow of fuel and air through the management subsystem and subsystem remote automated control of the backup synchronous diesel generator optional synchronous diesel generator. While Russ is icyhot average load of one synchronous diesel generator through the block parallel operation and if the average load on the machine will be 40% of nominal or less, it is distributed through rahimullah e-SOPS-regulators unevenly in relation to 60% to 20% accuracy in both directions up to 20% of the nominal capacity of a single synchronous diesel generator, with an average work load is 50% of the par in the ratio of 70% to 30% with accuracy in both directions up to 10%, with an average loading of synchronous diesel generator 60% and above - distribute the load equally with accuracy in both directions up to 15%. Moreover, the change of ratio, proportion and accuracy produce software automatically signal the current value of the average load on one synchronous diesel generator formed by the unit of parallel work. When the technical condition of one of the synchronous diesel generators worse than another, it is fixed switch technical condition on the unit of parallel work, after which the load between them are distributed randomly through the block parallel operation and rahimullah e-SOPS-regulators both synchronous diesel generators so that less serviceable unit load as much as he is able to develop power at a given frequency current and the angular velocity, and the rest of the load is transferred to the working unit. When the control criteria and increased the maximum above is gnosti power supply object load between parallel synchronous diesel generators are distributed in proportion to their rated capacity. When setting environmental management criterion synchronous diesel generators corresponding to the minimum environmental pollution, diesel generators signal subsystem upper level control is transferred to the light fuel and give effect to the standard means of purification and neutralization of exhaust gases from soot and harmful products of combustion, including increasing charge-air cooling by increasing the coolant flow through the air cooler, with load units and distribute the load between them in the same way, the same techniques and tools as in economic management criteria. During normal stop synchronous diesel generators, including the conclusion of one of the generators of parallel operation due to low loading, unloaded and disconnected from the power supply unit to stop after a short idling on podsyhanii angular velocityώpwith a,in addition to the stop operation stop the flow of fuel through the stop-device, single-channel mekhanogidravlicheskijj centrifugal speed regulator, and also due to the simultaneous cessation of air withfrom turbocharger boost by transferring reversible synchronous electric machine via the control system static poluprovodnikov Converter in the mode of forced electric braking. When entering the subsystem remote automated control of the working of synchronous diesel generator critical failure signal, in addition to off without prior discharge its generator breaker by subsystem remote automated control and stop the diesel engine by the stop-device, single-channel mekhanogidravlicheskijj centrifugal speed regulator, blocking the supply of fuel, and perform rapid electric braking turbocharger boost through reversible synchronous electric machine, stopping the flow of air and, in the exercise of block start routine. The sudden disappearance of voltage form its sensor voltage signal his disappearance, and sent it to the control subsystem top level, and the signal generated by the control subsystem top level and sent to an independent power from the emergency source group electric oil Sipper pump and controlled shutoff valves on its suction and discharge piping, pump oil two backup synchronous diesel generator, one of which is "on duty". In this case, prepared by the "duty" synchronous diesel generator at the command of his treatment tip can the system remote automated control immediately start, excite the angular speed dieselώpwith aand connected to the de-energized electrical generator through a switch. Thus, when the angular velocityώmincontrolled shut-off valves on its oil pipelines switch on it hung an oil Sipper pump, and power reversible synchronous electric machine for the initial acceleration of the turbocharger boost is produced from an emergency source. The other, unprepared synchronous diesel generator simultaneously with its maloprodaja produce blowing pustovojtenko pipeline and cylinder diesel engine through a system of compressed air and blow-off valves and pressure increase its lubricating oil to pre-launch values produce the cranking of the diesel engine by pnevmostartery under reduced pressure starting air, and then perform the same pneumatical starter three business start-UPS of the engine at normal operating pressure of the starting air and dispersed turbocharger boost through reversible synchronous electric machine operating as an electric drive motor and PI is emeu from the electrical outlet. With an increase in Alloway speed diesel to intermediateώ1fully translated into fuel for which off pneumatical starter, closing his check valves, switch lubrication system hung on oil Sipper pump, stop independent power group electric oil Sipper pump and close the controlled shut-off valve on its suction and discharge piping and bypass valve of the air cooler charge air. Next, the dispersed input normal diesel fuel through its optical mekhanogidravlicheskijj centrifugal speed regulator to podsyhanii angular velocityώpwith a,warm up a diesel unexcited synchronous diesel generator by idling at a given angular velocity. When the temperature of the cooling fresh water and lubricating oil of diesel engine to the prescribed values connected to the subsystem remote automated control of his previously disabled when the Parking sensors and carry out the same routine "monitoring of operating parameters by subsystem dis is Antonovo automated control, whereby dispersed diesel then to Sorgenfrei angular velocityώwith awith aand perform routine self-synchronization of the generator through the control unit of the Executive bodies of self-synchronization, after which connect the synchronous generator to the mains in parallel through the generator circuit breaker. If at the moment of disconnection of the power, none of the backup synchronous diesel generators were not in the "on duty", the signal subsystem top level management include independent power supply from the emergency source group electric oil Sipper pump and open controlled shutoff valves on its suction and discharge piping, pumped two unprepared synchronous diesel generator oil and simultaneously perform the purge piskovistovych pipelines and cylinders both synchronous diesel generators through a system of compressed air and blow-off valves. After raising the oil pressure first at any of these backup synchronous diesel generators to pre-launch values produce cranking its diesel by pnevmostartery, then apolnet three business start-UPS synchronous diesel generator the same pneumatical starter, open when you first start working bypass valve of the air cooler charge air and scatter its turbocharger boost through reversible synchronous electric machine using the emergency power supply. Upon reaching the angular speed of the diesel engine toώminin the same way transferred to fuel and lubricant hung from oil Sipper pump, close the bypass valve of the air cooler charge air and controlled shut-off valve on its suction and discharge oil from an independent group electric oil Sipper pump, and pipes starting air, dispersed diesel to podsyhanii angular velocityώpwith a,excite this synchronous diesel generator in the same way and connect it without warming up idling on de-energized electric system by means of its generator breaker. Moreover, the acceleration of the first pneumatical starter unprepared synchronous diesel generator supply of starting air to the second unprepared synchronous diesel generator temporarily blocked, and immediately, last the transition of the first synchronous diesel generator fuel at its intermediate angular velocity equal toώ1,start the routine start-up and acceleration to podsyhanii angular velocityώpwith athe second backup synchronous diesel generator in the same way that the first backup synchronous diesel generator, heated second unexcited backup synchronous diesel generator due to its idling, move on to the subroutine "control parameters" in the same way as for normal synchronous diesel generator, accelerated to Sorgenfrei angular velocityώwith awith a,smokingrelated generator through the control unit of the Executive bodies of self-synchronization, connect to the mains power supply by the generator circuit breaker and load it according to the given criterion control. If you want to run separate pumping lubrication systems, backup diesel generators with a single group of independent power electric oil Sipper pump select by switch the modes independent power group electric oil Sipper pump mode separate pumping, then the remote control switch set for each synchronous diesel generator on the operator's console, include for continuous operation independent power group electric oil Sipper pump and open simultaneously operated shut-off valves on the part of its suction and discharge nozzles only on pipelines pumped synchronous diesel generator and shut down independent group electric oil Sipper pump the same remote control switch or automatically by subsystem remote automated control immediately after entering into effect of this synchronous diesel generator and its hinged oil Sipper pump.

Better and more economical this embodiment of the method in which the maintenance mode "on duty" ready to start command subsystem remote automated control of lubrication diesel "on duty" synchronous diesel generator produces a continuous heated oil through such oil system directly working synchronous diesel generator, which is equipped with the auxiliary hinged oil Sipper pump and heat exchanger working synchronous diesel generator, which vannoy operations take cold from the crankcase of a diesel engine "on duty" synchronous diesel generator, let it cool oil through the coil of the auxiliary heat exchanger working synchronous diesel generator., through a casing which hung main oil pumping over the SPLA pumped hot oil worker synchronous diesel generator, disposed of due to this heat hot lubricating oil worker synchronous diesel generator cooling last noise flow of cold oil "on duty" synchronous diesel generator and simultaneously passing him the warmth of hot lubricating oil worker synchronous diesel generator, and the direction of flow of hot and cold oil in the auxiliary heat exchanger choose a counter, in this case, in the absence of necessary in the production of the "duty" of one of the synchronous diesel generators in the current mode and need the work of the subsidiary hung oil Sipper pump on the desktop synchronous diesel generator, it is removed from the work by releasing the clutch and operated shut-off valves on suction and discharge oil passages are closed.

Operational justified this embodiment of the method in which the subroutine enable synchronous diesel generator into the grid is performed so that after the operation of the acceleration heated synchronous diesel g is nerator fuel to podsyhanii angular velocity ω PSand subsequent time delay 2-4 with a measure in a particular case, the sensor voltage electrical power availability and the value of the voltage at the busbars of the main switchboard base plate; and in the absence of this voltage is connected to the excitation winding of the synchronous generator according to the signals of the control unit of the Executive bodies of self-synchronization to the automatic regulator of excitation of the generator by means of the damping device of the magnetic field and to the source of the bias - through device bias excited synchronous generator through its excitation regulator, measure the sensor voltage diesel generator voltage at its terminals when the voltage is increased up to 85% of the rated include generating the switch via the signal control unit Executive bodies of self-synchronization; and when the presence of voltage at the busbars of the main switchboard base plate; the signals generated by the control unit of the Executive bodies of self-synchronization, include simultaneously unexcited synchronous generator to the tires of the main raspedita via auxiliary contactor and limiting reactor, the excitation winding of the generator is connected to the automatic field controller through device damping of the magnetic field generator and simultaneously connect the to the same busbar, main switchboard base plate; a condenser battery via a contactless switch, produce a force excitation current of the synchronous generator through a current transformer its excitation regulator, after a time delay of about 0.5 seconds condensing battery off via its contactless switch, and after 0.5 s send control unit Executive bodies of self-synchronization enable signal generator switch simultaneously with the repeated signal connection to the tires of the main switchboard base plate; capacitor Bank through the same contactless switch, after closure of the generator breaker to signal its block contact coming into the control unit of the Executive bodies of self-synchronization, unlock auxiliary contactor in the value of the bounding reactor, and after a time delay 0.5 s off and the capacitor battery.

Economically and operational justified this embodiment of the method in which the measurement of the average load of one synchronous diesel generator in parallel operation produced by the subunit medium loading unit of parallel work, a comparison by Comparators average load with settings at 40%, 50% and 60% of nominal, which vzaimoosmotrov so that operation of the comparator greater load turns off the comparator minority is her download, in this case, if the average load on each generator will be equal to 40% of nominal or less, its uneven distribution between synchronous diesel generators in respect of 60% to 20% accuracy in both directions up to 20% of rated power produced by rahimullah electronic SOPS controls the flow of fuel and air by the fact that in specifying the inputs specified SOPS controllers send different sets of signals generated at the output of the integrator signal and adjusting the adjustable resistor setting unit parallel operation by means of an intermediate relay Comparators average load; if the average load on the generator will be equal to 50% of nominal, its distribution perform in the same way and similar funds in the ratio of 70% to 30% with accuracy in both directions up to 10% of rated power, and if the average load of the generator will be equal to 60% of nominal, relative load is distributed between synchronous diesel generators equally with accuracy in both directions up to 15% of rated power in accordance with the requirements of Russian Maritime register of shipping: the proportion of the distribution of loads between synchronous DISL generators periodically change through time relay included and switched off via the same intermediate relays, and given the e values of the accuracy of distribution regulate software-automatically by means of the adjusting resistors, installed on the input bias voltage amplifiers rahimullah electronic SOPS controls the flow of fuel and air, and the same intermediate relay unit of parallel work; and by reducing the average download two parallel working synchronous diesel generators to the minimum allowable value equal to 35% of rated power, the comparator average load in 35% of the nominal form the signal output from the parallel operation of one of the synchronous diesel generators, which is sent to the control subsystem top level and run it the program output this synchronous diesel generator, and after turning off its power switch subunit low boot block parallel block work through the block contact of this switch, also block comparator average load in 35% of the nominal and when the level of the average load to 40% of the nominal and up through intermediate relays this Comparer.

Technically justified this embodiment of the method in which, if the technical condition of one of the synchronous diesel generators worse than another, it is fixed through the switch condition, the relay technical condition and the auxiliary relay on the unit of parallel work, after which the load between them randomly distribute the exploits of the unit of parallel work and trichinoscope e-SOPS-regulator fuel and air intact synchronous diesel generator so less serviceable unit is transferred to the static regulatory feature by disabling it trichinoscope electronic SOPS control by a servo motor optical mekhanogidravlicheskijj centrifugal regulator angular velocity and load it manually so far as he is able to develop power at a given frequency current, and the rest of the load is transferred to the working unit specifying signal generated at the output of the differentiating device and sent via changeover contact auxiliary relay and integrator of signals for specifying the input trichinoscope e-SOPS-regulator fuel and air intact synchronous diesel generator.

Technically feasible, when you increase the static load on the power plant, the maximum signal power PMac apprin particular, equal to 80% of the nominal form by means of the comparator ultimate load trichinoscope e-SOPS-regulator at the output "V", which is sent to the control subsystem top level for commissioning of additional synchronous diesel generator.

Operational safer this embodiment of the method, when a sudden power outlet in the process of running two backup synchronous diesel generators, one of which is "on duty", pre-maloprodaja unprepared synchronous diesel generator hung produce oil Sipper pump "on duty" synchronous diesel generator after its dispersal pneumatical starter to intermediate angular velocity ω1what if this angular velocity managed open the isolation valves on the oil pipeline from unprepared synchronous diesel generator, and after overclocking it pneumatical starter to the same angular velocity ω1moving to his maloprodaja its own hinged oil Sipper pump, closing specified controlled shut-off valves than provide redundant independent power group electric oil Sipper pump.

Restrictive and distinguishing features of the claimed invention to provide, in aggregate, the solution of the problem to obtain the following results: a significant reduction (3-6 times) total cont is italinate input "on duty" (prepared) SDG in action the efficiency (degree of readiness and efficiency of operations in the "duty" of readiness, improving the reliability of running a diesel engine on the first try by increasing the probability of ignition at the first injection of the reinforced portions of the fuel and eliminate due to this detonation explosions during launch, improving efficiency and environmental performance of work SDG in static mode of low load and transient conditions surge/load shedding, improved dynamic characteristics SDG turbo, and hence the quality of electricity produced by them when a sudden vibration of the load, increasing efficiency of the unit in mode loads above 50% of the nominal, addressing modes surging of the turbocharger pressurization in the manipulation of his air damper and its rotation without lubrication period stop SDG, and reduce fire risk and effort on maintenance SDG.

1. So, due to the fact that: (a) "...in maintenance mode "on duty" ready to start command subsystem remote automated control of lubrication diesel "on duty" synchronous diesel-generator produce continuously heated oil through the oil system directly working synchronous diesel generator through its controlled shut-off and butterfly valves and Tr is Borovoy, equipped her for this..." (instead of periodic pumping oil at the expense of independent, Autonomous EMPN); b) in the same mode "...while additionally produce periodic cranking its crankshaft through pnevmostartery on low pressure compressed air and periodic draining pustovojtenko pipeline and cylinder diesel from condensing moisture through the starting system of compressed air and blow-off valve..." (in the prototype, these operations were performed in the period pre-start and start-up algorithms); C) exclude from known pre-private algorithm operation...advanced pump diesel through independent power Autonomous electric oil Sipper pump..." and starting from known private algorithm - operation...podmagnichivaniem synchronous generator through the device bias..." (as the generator include in the network, under voltage, unexcited); d) accelerate and enhance the reliability of ignition of the first portions of the injected fuel due to the fact that "...check the air temperature in the engine compartment,...when the air temperature in the engine compartment less valid continuum the air cooler charge air its diesel by-pass valve..." and that "...odnovremenno with the first enable pnevmostartery at the normal operating pressure at the start of the unexcited synchronous diesel generator produce acceleration and its turbocharger boost through its reversible synchronous the electric machine in the mode of a drive motor without interruption of its work during a possible starter pauses in the air, at the same time, the rotational speed of the turbocharger boost is set such that the value of the coefficient of excess air in the combustion chambers are launching a diesel corresponded to starting the supply of enriched fuel-air mixture..."; d) "...after the transition diesel fuel boost its flow, and in the period of forced software overclocking unexcited synchronous diesel generator fuel from the angular velocityώminto podsyhanii angular velocityώpwith aregulate and the excess air factor of the adaptive fuel mass injected by the synchronous change of the rotational speed of the turbocharger boost through its reversible synchronous electric machine and its static semiconductor Converter, controlled by signals sent to the control system static semiconductor transducer potentiometer monopulse mekhanogidravlicheskijj centrifugal regulator angular velocity, kinematically connected with the fuel rail given the CSOs centrifugal regulator angular velocity..."; e) "...increase the signal subsystem remote automated control of the angular velocity of the synchronous diesel generator to oversinging values ofώwith awith aby means of the servo motor optical mekhanogidravlicheskijj centrifugal regulator angular velocity, then perform routine self-synchronization of the generator is running synchronous diesel generator through the control unit of the Executive bodies of self-synchronization, after which connect the synchronous generator to the grid by the generator breaker..." (instead of the longer before switching routines precise synchronization of the prototype), - all this allows to reduce the start time of the backup SDG when you start on the first attempt from 30 s to 5 s, i.e. six times, and if diesel is started from the second or third attempt, this time is reduced to 8 and 11 with, i.e. almost four and three times.

Therefore, due to the fact that: 1) replace in the famous private algorithm "duty" willingness operation periodic pumping lubricating oil from independent power Autonomous ANN on continuous pumping of heated oil from NNN work through SDG managed Zapovednik is hydrated and the throttle valve; 2) move in this particular algorithm operation periodic cranking diesel and periodic draining pustovojtenko pipeline and cylinder diesel from moisture; 3) exclude from pre-private algorithm operation additional continuous pumping of oil from independent power ANN, and from known starting private algorithm operation the bias generator; 4) accelerate the delivery and improve the reliability of ignition of the first reinforced portions of fuel to be injected, 5) increase the force software overclocking diesel fuel to podchinenni angular velocity ωPSwhile maintaining the optimal value of the air excess factor, 6) substitute the known routine precise synchronization of the excited generator routine reactor-condensational self-synchronization of non-excited generator, reduce the total duration of the input backup SDG in (3-6) times.

1. These distinguishing features of the claimed invention: (a) "...in maintenance mode "on duty" ready to start command subsystem remote automated control of lubrication diesel "on duty" synchronous diesel-generator produce continuously heated oil through the oil system directly working synchronous di is spruce generator through its controlled shut-off and butterfly valves and piping, equipped her for this..." (instead of periodic pumping from independent power EMPN) - this operation level and raise to a higher level is pre-pressure lubricating oil than contribute to filling them and its penetration into all the gaps of friction pairs of diesel engine, and increase the efficiency, and hence the degree of readiness of the lubrication system; and due to the fact that the oil is pumped through NNN working SDG already heated, eliminates the necessity of heating in makepathsrelative and saves energy costs for this operation; simultaneously, it eliminates the need for cooling hot oil worker SDG in its regular cooler, because it is mixed with cold oil "on duty" SDG than the saving of energy costs in the oil cooling of the working SDG; b) "...in addition produce periodic cranking its crankshaft through pnevmostartery at reduced pressure compressed air..." - this operation creates and maintains the oil film between those surfaces of friction pairs, where the flow of oil from stationary diesel is difficult, and operation "...while additionally produce ...periodic draining pustovojtenko pipeline and cylinder diesel from condensed moisture is through the launch of the compressed air system and the purge valve..." prevent water hammer in the time of the filing of the pneumatical starter inrush of air, make sure the system running and reliable (no gaps) ignition first, not diluted by moisture servings injected into the combustion chamber fuel is thereby provide and maintain a high degree of system availability start and the diesel for immediate start-up without the need for any additional training after receipt of the command to run. Thus, increasing the overall reliability of the start on the first attempt than saving the total air flow to run and energy on its completion.

Therefore, the claimed distinctive signs "maintain duty alert" ("hot standby"), consisting in the fact that "...the grease diesel "on duty" synchronous diesel-generator produce continuously heated oil through the oil system directly working synchronous diesel generator..."and "...periodically crank the crankshaft of diesel engine ...and periodically drain posovszky piping and cylinders diesel from moisture...", increase the effectiveness of training and readiness diesel, increases the probability of starting at the first attempt and save the energy consumption for heating oil "on duty" SDG, oil cooling working SDG and maintaining the pressure of compressed air in its cylinders.

3. As is known, the reliability of ignition of the first parti is injected enriched fuel-air mixture is determined by many factors, including: the degree of training of the combustion chamber (initial temperature of its walls), initial temperature (viscosity) of the lubricating oil, the temperature of the charge air mass mixing ratio of fuel-to-air during injection of the first portions of the fuel, the quality of mixing. The last factor determined by the shape of the combustion chamber and the angular velocity ωmin. In the prototype, and the invention they are the same. However, the previous factors are different.

In the invention due to:

a) distinguishing features - 1) grease SDG "...in maintenance mode "on duty" ready to start command subsystem remote automated control of lubrication diesel "on duty" synchronous diesel-generator produce continuously heated oil through the oil system directly working synchronous diesel generator through its controlled shut-off and butterfly valves and piping, fitted on it ...and 2) "...and the temperature of the pumped lubricating oil and fresh water through their thermostats produced in accordance with software-defined subsystem remote automated control values calculated it based on measurements of environmental parameters environment..." - in anticipation of the launch backup SDG initial mn of the treatment temperature of its lubricating oil and the walls of the combustion chambers support optimal the relevant parameters of the ambient air in the absence of a load unit;

b) a distinctive feature - "...while additionally produce ...periodic draining pustovojtenko pipeline and cylinder diesel from condensing moisture through the starting system of compressed air and blow-off valve..." - from the combustion chamber promptly remove condensing and accumulating moisture, the presence of which in the period of starting the diesel engine can cause water hammer and the failure of the first attempt of launch;

C) the distinguishing sign "...check ...the temperature in the engine compartment, ...when the air temperature in the engine compartment less valid continuum the air cooler charge air its diesel by-pass valve..." - in the cold season could prevent overcooling of the first portions of inlet air and to increase the probability of ignition of the combustible mixture;

g) a distinctive feature - "...and at the same time with the first enable pnevmostartery at the normal operating pressure at the start of the unexcited synchronous diesel generator produce acceleration and its turbocharger boost through its reversible synchronous electric machine in the mode of a drive motor without interruption of its work during a possible starter who's pauses in the air, in this case, the rotational speed of the turbocharger boost is set such that the value of the coefficient of excess air in the combustion chambers are launching a diesel corresponded to starting the supply of enriched fuel-air mixture..." - the component ratio of the combustible mixture "fuel-air" at the time of fuel injection set optimal, causing it to reliably ignites and burns (oxidizes) all without a trace.

Therefore, the set of distinctive features: continuous pumping of lubricating oil "on duty" by SDG NNN work through SDG controlled shut-off and butterfly valves, the formation of the set values of the initial temperature of the coolant and lubricating oil "on duty" SDG in function of the current environmental parameters in the engine compartment (MO), periodic draining of the air pipes and cylinders "on duty" SDG from condensed moisture, the bypass air cooler charge air to the start time of SDG at low temperature in MO, commissioning TKN simultaneously with the first working attempt to start the diesel engine due to the inclusion of OEM mode drive motor and setting the rotational speed of the turbocharger, the appropriate starting value of the coefficient of excess air have resulted in the increase reliable the STI ignition and complete combustion of the first reinforced portions of the injected fuel, consequently, the probability of starting the diesel engine at the first attempt.

4. In the analogues and the prototype, as seen above, uses a turbocharger with a free turbo, i.e. overclocking and rotate only the exhaust gases of the diesel engine. Such TKN when a sudden load increase of fuel supply is not accompanied by adequate surge pressure charge air. Recent increases smoothly and slowed by the inertia of TKN and, therefore, lags in phase. The coefficient of excess air in the combustion chamber is low throughout the transition period, while TKN will not reach a new steady state. Due to lack of oxygen, the fuel is burned (oxidized) not completely, is smoky exhaust clogging up the fire soot collector, turbine TKN and exhaust tract, and release into the environment nedouchivshihsya products of combustion of harmful gases: NOx, CO, SOxCxHx, aldehydes, etc. The same is observed in static modes DG bulk load for the reason that due to the reduced speed TKN in these modes, the performance is insufficient to provide optimal coefficient of excess air in the combustion chambers. As a result, the efficiency and environmental performance of SDG in these modes are reduced.

In the present izaberete the AI TKN equipped additionally osem. Therefore, when the load, including the injection during the launch of the first portions of the enriched fuel-air mixture such distinctive features as: a) "...and at the same time with the first enable pnevmostartery at the normal operating pressure at the start of the unexcited synchronous diesel generator produce acceleration and its turbocharger boost through its reversible synchronous electric machine in the mode of a drive motor without interruption of its work during a possible starter pauses in the air, at the same time, the rotational speed of the turbocharger boost is set such that the value of the coefficient of excess air in the combustion chambers are launching a diesel corresponded to starting the supply of enriched fuel air mixture..."; b) "...when running synchronous diesel generator in the range of static active loads less than 50% of the nominal and sudden surge of significant power is measured by trichinoscope e-SOPS-regulator fuel and air signals static and dynamic increment of this power, coherent and synchronous boost these signals, the supply of fuel and the pressure of the charge air by that act a static signal to the servo motor optical mekhanogidravlicheskijj centrifugal regulator angular / min net and, and dynamic control system static semiconductor Converter, increasing the tension of the last and torque electromagnetic torque reversible synchronous electric machine, operating the driving motor...provide in the run mode, transition mode and static modes incomplete load SDG optimum mixing ratio of fuel-to-air, ensuring complete combustion (oxidation) of individual hydrocarbon vapor mixture without the formation of soot and harmful (nedouchivshihsya) products of combustion. The same purpose is achieved and when performing the operation "...after the transition diesel fuel close the bypass valve of the air cooler (give effect to the cooler charge air)...". It is known that lowering the temperature in the combustion chamber contributes to the decrease in the proportion of harmful gases NOxincreases the specific weight of the air.

The following distinctive features - "...in the operating mode of the diesel generator is measured by the respective sensors of temperature, pressure and humidity, as well as the current load synchronous diesel generator is determined from the measured values, by means of its subsystems remote automated control of the calculated optimum temperature of the unit and form a new set meant what I temperature of cooling water and oil, refer to the appropriate sets the input temperature of cooling water and lubricating oil and regulate these thermostats are set temperatures..." - ensures the optimal values of the temperatures of the combustion chamber walls and settings lubricating oil, in which the efficiency of the diesel engine and environmental performance of its work under the current conditions the best.

Thus, the characteristics group a) and b) of this clause provides, in aggregate, more full (economic) combustion and improve environmental performance SDG on all modes due to more complete oxidation of the exhaust gases. Cost SDG increases further and also due to sign in): "...when a static resistive load synchronous diesel generator above 50% of rated reversible synchronous electric machine is transferred to the generator mode by inverting the static semiconductor Converter on the sensor signal idle this car, fixing the moment of its transition to the idle mode, in this case, electrical energy is reversible synchronous electric machine, produced in the generator mode, refer to the electrical network through the chain of her power...". This feature allows you to dispose of that part of the exhaust gases of a diesel engine, in which the analogues and p is ototype are directed into the exhaust pipe, to prevent these modes excessive performance TKN with a free turbo.

Therefore, using a combo drive TKN (through gas turbine and Osam), as well as descontrolada cooler on the run is complete SDG, as well as the regulation of the set values of the temperature of cooling water and lubricating oil in the function of current values of load, temperature, pressure and humidity increase the economic and environmental performance SDG in static modes in the whole range of loads and transient conditions associated with a sharp surge/load shedding.

5. As noted in paragraph 4, TKN with a free turbo, which is applied in the prototype, when a sudden load increase of fuel supply is not immediately followed by a corresponding increase in the pressure of inlet air due to the inertia of the high speed TKN. The delay variation of the pressure charge air forces to reduce the degree of force fuel and torque of the diesel engine, in order to avoid or at least reduce the smoke emitted in transient conditions. Recovery time, speed - time reception of the load increases. The quality of produced electric energy is deteriorating. The same is true when d is a minimum load shedding SDG.

In the invention distinguishing characteristics: a) "...when running synchronous diesel generator in the range of static active loads less than 50% of the nominal and sudden surge of significant power is measured by trichinoscope e-SOPS-regulator fuel and air signals static and dynamic increment of this power, coherent and synchronous boost these signals, the supply of fuel and the pressure of the charge air by that act a static signal to the servo motor optical mekhanogidravlicheskijj centrifugal regulator angular velocity, and dynamic control system static semiconductor Converter, increasing the tension of the last and torque electromagnetic torque reversible synchronous electric machine working drive engine, and with a sharp discharge of significant power in this range of static loads measured in the same trichinosis e-SOPS-regulator fuel and air signals static and dynamic reduction of this capacity, which consistently and synchronously deviceroot fuel supply and pressure charge air diesel by that act on the servo optical mekhanogidravlicheskijj centrifugal regulator coal is howling and speed control system static semiconductor Converter, than reduce the tension of the last and torque electromagnetic torque reversible synchronous electric machine..."and b) "...when the synchronous operation of the diesel generator in the range of static active loads above 50% of the nominal and sudden surge of significant power is measured in the same way the signals static and dynamic increment of this power, coherent and synchronous boost these signals, the supply of fuel and the pressure of the charge air by the fact that the static signal affect the servo optical mekhanogidravlicheskijj centrifugal regulator angular velocity and increase the flow of fuel and dynamic control system static semiconductor Converter, lower than the current last and brake electromagnetic torque reversible synchronous electric machine working as a generator, and when a sudden discharge of significant power in this range of static loads fuel and boost pressure diesel in the same way and by the same means, simultaneously and consistently deviceroot...", - ensure synchronicity forces (or deportirovat) fuel supply and pressure of inlet air. Therefore, the level of these forces may be increased. This will lead to more rapid change in torque is the isel and reduce time transients - receiving load. The electrical energy parameters in dynamic modes SDG thus improved.

Therefore, distinguishing features (a) and (b) the claimed invention, referred to in paragraph 5, improve dynamic characteristics SDG combined with turbocharging with a sharp vibration of the load, and hence the quality of the electricity produced by them.

6. In the prototype the load range SDG above 50% of its nominal TKN develops excess capacity, resulting in excess excess factor charge air in the combustion chamber, lowering the temperature and pressure of the exhaust gas and the deterioration of environmental performance exhaust gases group COxand CH. To avoid this part of the exhaust gas perepuskat, bypassing the turbine of the turbocharger in the exhaust pipe. That is, this part of the exhaust gas SDG in the prototype is not utilized and does not bring advantage.

In the invention distinguishing characteristics: "...in the operating mode with increased static active load on a synchronous diesel generator as its reception and, accordingly, the continuous increase of the torque developed by the turbine of the turbocharger boost, torque electromagnetic torque reversible synchronous electric machine, the servant of the melting of the driving motor, adequately reduced by reducing the voltage of the static semiconductor transducer signal generated trichinosis e-SOPS-regulator fuel and air, when the static resistive load synchronous diesel generator above 50% of rated reversible synchronous electric machine is transferred to the generator mode by inverting the static semiconductor Converter on the sensor signal idle this car, fixing the moment of its transition to the idle mode, in this case, electrical energy is reversible synchronous electric machine, produced in the generator mode, refer to the electrical network through the chain of her power..." - eliminates the need for bypass part of the exhaust gas in the exhaust pipe, disposing of their energy into electrical energy. The efficiency of a diesel generator in this mode increases.

Therefore, by distinguishing characteristic is "Under load DG above 50% of rated ...reversible synchronous electric machine is transferred to the generator mode by inverting the static semiconductor Converter on the sensor signal idle this car, fixing the moment of its transition to idle mode..." - the efficiency of the unit in mode loads above 50% of the nominal increases.

7. In the prototype the chronic is the first lag of the change of pressure charging air from changes in fuel in transient conditions and low excess air coefficient in the static modes SDG bulk loads (less than 50% of nominal) causes incomplete combustion of fuel and clogging of the combustion chambers of the diesel engine, its collector blades and internal cavities of the gas turbine, as well as the entire exhaust line of fire soot. When this heat-exchange processes and thermal regime of the diesel engine, TKN and exhaust tract change, and the resistance of the latter increases, which eventually leads to the lowering of the efficiency of a diesel generator. To avoid these consequences, it is necessary as often as possible to spend motocade diesel, it TKN and nodes exhaust tract: spark arrestor and noise reduction. Work on the service LDH increase, their cost also.

In the invention a number of distinctive features in conjunction associated with a combo drive TKN and software running his osem and CAF in the starting, transient conditions SDG and static modes with a load of less than 50% and more than 50% of the nominal, such as, and) "...and at the same time with the first enable pnevmostartery at the normal operating pressure at the start of the unexcited synchronous diesel generator produce acceleration and its turbocharger boost through its reversible synchronous electric machine in the mode of a drive motor without interruption of its work during a possible starter pauses in the air, at the same time, the rotational speed of the turbocharger boost set such that the value is their coefficient of excess air in the combustion chambers are launching a diesel corresponded to starting the supply of enriched fuel-air mixture, ...in the period of forced software overclocking unexcited synchronous diesel generator fuel from the angular velocityώminto podsyhanii angular velocityώpwith aregulate and the excess air factor of the adaptive fuel mass injected by the synchronous change of the rotational speed of the turbocharger boost through its reversible synchronous electric machine and its static semiconductor Converter, controlled by signals sent to the control system static semiconductor transducer potentiometer centrifugal regulator angular velocity, kinematically connected with the fuel rail, this centrifugal speed regulator..."; b) "...in the operating mode with increased static active load on a synchronous diesel generator as its reception and, accordingly, the continuous increase of the torque developed by the turbine of the turbocharger boost, torque electromagnetic torque reversible synchronous electric machine working drive engine adequately reduced by reducing the voltage of the static p the semiconductor transducer signal, generated trichinosis e-SOPS-regulator fuel and air..."; "...when running synchronous diesel generator in the range of static active loads less than 50% of the nominal and sudden surge of significant power is measured by trichinoscope e-SOPS-regulator fuel and air signals static and dynamic increment of this power, coherent and synchronous boost these signals, the supply of fuel and the pressure of the charge air by that act a static signal to the servo motor optical mekhanogidravlicheskijj centrifugal regulator angular velocity, and dynamic control system static semiconductor Converter, increasing the tension of the last and torque electromagnetic torque reversible synchronous electric machines, operating motor drive..."; d) "...when the synchronous operation of the diesel generator in the range of static active loads above 50% of the nominal and sudden surge of significant power is measured in the same way the signals static and dynamic increment of this power, coherent and synchronous boost these signals, the supply of fuel and the pressure of the charge air by the fact that the static signal affect the servo motor toimpose mekhanogidravlicheskijj centrifugal regulator angular velocity and increase the flow of fuel, and dynamic control system static semiconductor Converter, lower than the current last and brake electromagnetic torque reversible synchronous electric machine working as a generator...", - contribute in aggregate optimization in the specified modes of air excess factor, more complete fuel combustion and a reduction in the combustion products carbon ingredients. This, in turn, reduces the number of masochistic diesel, TKN and components of the exhaust tract and reduces the fire risk SDG in General.

Therefore, the total effect of the distinguishing characteristics a), b), C) and d) reduces the degree of clogging of the combustion chambers of the diesel engine and the turbine and the exhaust duct through which exhaust gases, solid products of combustion soot and reduces the number of masochistic, with the consequence of reducing the complexity of the service SDG and its fire hazards, i.e. leads to the achievement of sverhsummarny effect.

The same result is aimed and the following characteristics: e) "...with the economic criteria control the number of running generators imposed at the rate of their load about 80% of the rated based on the best efficiency units, and with greater loading trigger signal trichinoscope electronic SOPS control the flow of fuel and air through the subsystem management is placed top-level and subsystem remote automated control of the emergency diesel generator optional generator they expect average download one by DG unit parallel operation and, if the average load on the generator will be 40% of the nominal, it is distributed through rahimullah e-SOPS-regulators unevenly in relation to 60% to 20% accuracy in both directions up to 20% of rated power one SDG, with an average loading of SDG 50% of the par in the ratio of 70% to 30% with accuracy in both directions up to 10%, with an average loading of SDG 60% and above - distribute the load equally with accuracy in both directions up to 15% of the nominal moreover, the change of ratio, proportion and accuracy produce software automatically signal the current value of the average load on one synchronous diesel generator formed by the unit of parallel work; the proportion of the distribution of loads between synchronous DISL generators periodically change, in particular through time relay included and switched off via the same intermediate relay, and the values the accuracy of the distribution governing the program-automatically, in particular by adjusting resistors installed on the input bias voltage amplifiers rahimullah electronic SOPS controls the flow of fuel and air, and the same intermediate relay block parallel operation...".

The goal pursued the priest the temporal loading parallel SDG shorter, the more power, is that in the period SDG with a load of 60% or more is self-cleaning combustion chambers of the diesel engines and their exhaust tracts of soot due to its burnout when increasing the temperature of exhaust gases. When informed this software automatically changes the accuracy of the distribution of loads at different specified proportions aims to achieve a sufficient reduction in the frequency of impacts of electronic SOPS controllers for servo motors DRS - the most intense level of automated SDG and prolong their service life by saving their resource.

8. Distinguishing features of the claimed invention - "...at the conclusion of one of the generators of parallel operation due to low loading, unloaded and disconnected from the power supply unit to stop after a short idling on podsyhanii angular velocityώpwith a,in addition to the stop operation stop the flow of fuel through the stop device monopulse mekhanogidravlicheskijj centrifugal regulator angular velocity and also due to the same-mango stop the flow of air from the turbocharger boost by transferring the skimmed milk is my synchronous electric machine via the control system static poluprovodnikov Converter in the mode of forced electric braking..." - eliminates rotation TKN free run after stopping the diesel engine and its NMPN, thanks to forced electric brake OEM. Consequently, these signs protect bearings TKN from dry friction than extending the resource.

9. The characteristics of the claimed invention - "...with the arrival of the subsystem remote automated control of the working of synchronous diesel generator critical failure signal, in addition to off without prior discharge its generator breaker by subsystem remote automated control and stop the diesel engine by the stop-optical device mekhanogidravlicheskijj centrifugal speed regulator, blocking the supply of fuel, and perform rapid electric braking turbocharger boost through reversible synchronous electric machine, stopping the flow of air and, in the exercise of blocking podgram run..." - nullifies the likelihood of surging operating modes of the turbocharger, as the closing of the damper is accompanied by a forced stop TKN.

Consequently, the use of electric braking of osem when closing the intake tract TKN air baffle prevents it surge

It is essential that a significant proportion of the kinetic energy stored in the rapidly rotating TKN, not lost useless for heating bearings (as in free run), and is converted into electrical energy with her recovery in the electrical network.

Partial recovery of electricity is also observed and the following characteristics of the invention: "...when the synchronous operation of the diesel generator in the range of static active loads above 50% of the nominal and sharp ...reset considerable power in this range of static loads fuel and boost pressure diesel in the same way and by the same means, simultaneously and consistently deviceroot..."than increase brake electromagnetic torque of osem and accordingly energy recovery.

Therefore, entered the sign generator (regenerative) braking TKN at sharp discharges the load on the SDG and full stop TKN due to OEM under normal and emergency modes SDG - enhance the efficiency of the generator set.

Thus, we achieve the goal of the project.

Figure 5 shows another, namely a special case of the use of the method, a sample implementation and use of joint lubrication system synchronous diesel generators. It differs from the first example, as the General case (figure 1), the fact that the crankshaft of each SDG hinged, two hinged oil Sipper pump (NNN), which produced pumps 5.1 (5.2) are regular (core), and pumps 89.1 (89.2) - auxiliary, designed for continuous pumping lubrication system "on duty" SDG due to the energy working SDG. Between the drive shafts of the regular and auxiliary pumps in this case installed releasing the clutch 90.1 (90.2). Before suction cavities both NNN are auxiliary heat exchangers 91.1 (91.2)used for cooling hot oil working SDG and at the same time for the disposal of its heat by preheating cold oil "the duty of the SDG. Accordingly, the input connections (not shown) of the auxiliary heat exchanger is connected with a piping hot oil working SDG and piping cold oil "on duty" SDG, and output it to the nozzles (not shown) with suction cavities of both pumps. For control of flow of the heated lubricating oil "on duty" SDG is controlled shutoff valve 92.1 (92.2) and the throttle valve 8. Because pre-pressure in the lubrication system "on duty" SDG lower than the working pressure of the working SDG, auxiliary NNN 89.1 (89.2) can be set lower productivity.

Moreover, the unit of parallel work 41 (figure 2) in the particular case of execution of the method also includes the sub output from SDG parallel operation when load is low. It consists of a comparator 93 a low boot that is configured on the setpoint of 35% of rated power adjusting resistor 94. In the output circuit of the comparator is connected in series trailing block contacts generator circuit breakers 4.1 and 4.2. The unit 41 parallel operation also included the Executive relay 95 high reliability and relay 96 maximum reliability of power supply of the object. They are powered by switch 47 criteria for the management of power plant in the formulation of its second and third positions matched with the public.

The method of automated control Sdgm in the automated plant is as follows. Full cycle SDG divided into four modes: mode of maintaining the status of "duty" ready to start, and the adoption load ("hot standby", "stand by"), the input mode is in effect, the operating mode stand-alone (single) operation and operating mode of parallel operation. Accordingly, and process management SDG divided into four subprocesses. Management SDG alternately in each of these subprocesses separately carried out in the following order.

1. Management of synchronous diesel generator maintenance mode "duty" of readiness ("hot standby", "stand by")

For example, the current load of the power plant provides the working of synchronous diesel generator SDG (figure 1): 1.1 (not shown) is 2.1, and the "duty" is synchronous diesel generator SDG2: 1.2-2.2. Standby mode synchronous diesel generator, located in the reserve, set switch sequence (not shown)installed on the operator console 44. Through subsystem 34.2 DAU "standard" synchronous diesel generator 1.2-2.2 recent support in the ready state, which perform the preparatory operation: pump diesel 2.2 through the respective thermostats - fresh water (not shown) and oil 28.2 - on retime lubricating oil and fresh water, periodically blow compressed air posovszky piping and cylinders diesel from condensing moisture, occasionally crank it crank and keep the generator 1.2 razvodnym.

This pumping "on duty" SDG2 lubricating oil is produced using hinged produced pump, for example, 5.1 working diesel 2.1. For this purpose, the signal sent by the subsystem 34.2 DAU, open controlled shut-off valves 6 and 7, take the oil through the pump 5.1 working diesel generator SDG from the crankcase 9.2 "on duty" SDG2 and served through the throttle valve 8 and thermostat 28.2 in the lubrication system "on duty" SDG2. To the suction hung produced pump 5.1 two-flow lubricating oil is hot from working SDG and cold of a "duty" SDG2 mix, cooling the first and second fueling the flow of lubricating oil, so that further cooling the first stream in its regular oil cooler (not shown), the pumped sea water, and heating the second stream is not required. For this reason, receive savings of energy consumption for these two operations. Energy save more and due to the fact that they did not use day pumping "on duty" SDG2 independent power group ANN 10. This saves another resource that ANN. Pre-start oil pressure is SDG2 support below the operating pressure in SDG, what warmed oil after maloprodaja maintaining pump 5.1 pass through the throttle valve 8. Pumping "on duty" SDG2 perform continuously, resulting in a pressure of lubricating oil in it constant support, without pulsations. When in this mode of lubrication all the gaps between the friction á filled with oil, eliminating the possibility of dry friction with a sudden start "on duty" SDG2.

The disadvantage of this method of lubrication "on duty" SDG is the necessity of mixing the oils work and "regular" units, and the possibility of migration of contaminants from the crankcase of one SDG in the lubrication system of the other. More cost effective resource is the second example of the same method of pumping that serves as a particular case of the method, which does not have this drawback (figure 5). It is that in the "hot standby" grease diesel 2.2 "duty" SDG2 produce continuously through open through subsystem 34.2 DAU operated shut-off valves 6.2, 7, 92.2 and the throttle valve 8 heated oil from the other included coupling 90.1 (auxiliary) NNN 89.1 diesel 2.1 working of a diesel generator SDG that take away from the crankcase 9.2 "on duty" diesel 2.2, miss cold oil through the coil of the auxiliary heat exchanger 91.1 working diesel engine 2.7, through the casing of which the first (main) NNN 5.1 pumped hot oil is working diesel 2.1, taken from Carter 9.1 working diesel 2.1, disposed of due to this heat hot lubricating oil working diesel 2.1 and cool the flow of cold oil "on duty" diesel 2.2, and the direction of flow of hot and cold oil in the auxiliary heat exchanger 91.1 choose counter. Additional cooling of the working oil diesel 2.1 in its regular oil cooler (not shown), the staff of the pumped sea water, is not required. And, there's no additional heating oil "on duty" diesel 2.2 in its regular makepathsrelative (not shown). Moreover, this method of pumping is used only when a backup SDG in the "Hot standby" ("stand by", "duty"). In the absence of necessary in the production of the "duty" of one of the SDG in the current mode of the power plant and necessary in the work of subsidiary NNN 89 on the desktop SDG, it is removed from the work by releasing the clutch 90, and valves for oil pipelines closed.

The temperature of the oil "on duty" diesel 2.2 in both cases maintain its readiness regulate thermostat 28.2 (figure 1, figure 5) corresponding to the idling mode of the unit, as well as temperature, pressure and humidity of the environment. This temperature Tass mset subsystem 34.2 DAU duty SDG2 (after signal processing e what about the corresponding sensors not shown) and compared with the actual oil temperature Td mcrankcase 9.2 through comparator 29.2

Along with masoprocol have a "duty" SDG2 is heated and pumped in a similar fashion and for similar circuit (not shown) zerobalance space cooling fresh water working diesel generator SDG.

In addition to these operations periodically crank the crankshaft of the diesel 2.2 and maintain an oil film on those of the rubbing surfaces, where penetration of oil from a fixed "on duty" diesel is difficult. For this purpose, a specified program intervals by signals generated by the subsystem 34.2 DAU, served starting air through controlled shutoff valve 16.2 and pressure reducing valve 18.2 pneumatic engine 15,2 (figure 1). Due to the low angular velocity of the engine is obtained by lowering the air pressure, produce 1-2 slow turnover.

To prevent condensation in the pipes starting air (not labeled) and cylinders (not labeled) of the non-working diesel 2.2, the signals generated by the software subsystem 34.2 DAU duty SDG2, they are periodically rinsed in a known manner by compressed air on the same system through the purge valve (not shown).

Throughout a "duty" mode SDG2 it is the excitation winding 27.2 (1, 4) hold a closed-circuited through the device 26.2 damping of the magnetic field generator. This razvorujut broken synchronous generator 1.2 and support its unexcited during start-up to connect to the tire 3 MSB under tension.

2. Management SDG input mode in action

When you receive the command to run, for example, by pressing 35.2 remote start (figure 1), or, in the particular case, the signal "load 80% rated" (figure 2)generated at the output "V" trichinoscope (combined) e-SOPS-regulator 39.1 working SDG and sent the arrow "b" in the control subsystem 43 top level, going straight (under conditions that pre-pressure of lubricating oil in normal and generator 1.2 is not excited, certainely respectively, a pressure sensor (not shown) and the sensor voltage generator to 46.2 first attempt at overclocking "on duty" diesel 2.2 pneumatical starter 15.2. For this purpose on the "start" command subsystem 34.2 DAU open controlled shut-16.2 and bypass 17.2 valves and serves on the pneumatical starter 15.2 within 2-3 with compressed air normal operating pressure. Synchronously with this through her open bypass valve 25.2 on the cooler 24.2 (in cold weather, if the ambient temperature in the engine compartment below army) and acting subsystem 34.2 DAU system 23.2 control static semiconductor Converter 22.2 include OEM 21.2 mode of a drive motor. Diesel 1.2 and turbocharger boost 20.2 dispersed: the first is through pnevmostartery 15.2 to the minimum angular velocity ωminwhere possible steady his work on the fuel, and the second through OEM 21.2 to the angular speed at which the optimum excess air coefficient to the time of injection of the first portion of fuel into the combustion chambers of the diesel 2.2 for education enriched fuel-air mixture.

If this attempt is unsuccessful, make a break in pnevmostartery 2-3 with what command subsystem 34.2 DAU valves 16.2 and 17.2 closed without interrupting the operation of the turbocharger 20.2 charge and without closing the bypass valve 25.2. Then produce in the same sequence a second attempt dispersal pneumatical starter 15.2, and in case of its failure, then after the second pause, and the third a similar attempt. In the event of a run on the third attempt subsystem 34.2 DAU, which control the number of times you run, include a known manner the fault and give effect to the routine protection against faults. Such development is possible, but unlikely.

Usually prepared in advance "duty is the" SDG2 in a well-organized process run (steady acceleration to ω minoptimally matched initial temperature of lubricating oil and cooling fresh water, as well as the necessary optimally chosen ratio of the first portion of the mixture "fuel-air") is guaranteed with probability close to one, start on the first attempt. After sustained ignition of the combustible mixture (i.e. after accelerating to the intermediate angular velocity ω=ω1by subsystem 34.2 DAU on SDG2 close synchronously operated shut-off and bypass valves 16.2 and 17.2 (off the starter 15.2), close the bypass valve 25.2 (include in the circuit charge air cooler 24.2), close controlled shut-off valves 6 and 7 (or 6.2, 7 and 92.2 figure 6) on oil pipelines NNN 5.1 (1) working diesel 2.1, since moving to the pumping of lubricating oil through its NNN 5.2 input SDG2, dispersing its diesel 2.2-known way to podsyhanii angular velocity ωPSdue to accelerated software forces the fuel with subsequent deceleration via monopulse mekhanogidravlicheskijj centrifugal regulator 30.2 angular velocity and change synchronously-in concert with the fuel ratio of the excess charge air due to the impact on the speed of OEM 21.2 turbocharger 20.2 static poluprovodnikovogo 22.2 and its systems 23.2 control, which affect the signal produced by potentiometer 49.2 (figure 2), the movable contact of which is connected kinematically with the fuel rail 48.2.

After the release of SDG2 on the angular velocity ωPSmake time delay 2-4 with that all operating parameters SDG2 has become the norm. Along with this subsystem 34.2 DAU (figure 1) establishes a new, higher set-point temperature of lubricating oil Tass mthat is sent to the comparator 29.2 predetermined oil temperature thermostat 28.2. Similarly, changing the set-point temperature fresh water cooling Tassthat is sent to a comparator (not shown) of the set temperature of thermostat fresh water. Both support the new thermostat setpoints operating temperatures.

After the specified delay to the subsystem 34.2 DAU connect those sensors (not shown)which, at the time of Parking off to avoid false positives. From this moment begin to implement a known manner well-known private subroutine "Control of operating parameters and fault protection". This training SDG2 to the inclusion finish and start the routine inclusion in the grid.

To do this synchronously checked by a sensor 45 network voltage (figure 4) and the voltage value on the tires 3 MSB. Info is the information about the voltage sent to the input "b" block 40.2 control the Executive bodies of self-synchronization. However, the routine inclusion SDG2 in the grid may be, in the particular case, according to various algorithms, depending on the initial conditions. If there is no voltage in the power network based on the information of the sensor 45, an impact block 40.2 (figure 1, figure 4) management Executive bodies of self-synchronization (signal at the output "d") at device 26.2 damping of the magnetic field generator and connect them winding 27.2 excitation synchronous generator 1.2 to his automatic regulator 33.2 excitation and output signal "g" is connected to the same winding and to the source of pediatrician 88 (figure 4) through contactor 87.2 bias. Due to this, the generator 1.2 Pogranichnaya and then snowspeeders through its ARV 33.2. However, if you increase the voltage of the generator 1.2% to 85% of nominal, which is measured by the sensor 46.2 voltage generator includes a generator switch 4.2 signal generated at the output of "W" block 40.2 control the Executive bodies of self-synchronization. After closure of the switch 4.2 block contact (not shown) sends a signal zero input "C" block 40.2 control the Executive bodies of self-synchronization, which removes the power of this unit, and thereby unlock all control circuit (not shown).

If the data of the sensor 45 is constrained by what their tires 3 MSB is available, it is performed by block 40.2 control the Executive bodies of self-synchronization routine reactor-condenser self-synchronization and inclusion in this particular case in the following sequence. A single signal produced its output and affect the servo motor 31.2 and increase the angular velocity SDG2 to oversinging values of ωcc. After this individual output signals "C", "e" and "d" block 40.2 control the Executive bodies of self-synchronization respectively perform the following simultaneous steps: a) include an auxiliary contactor 83.2 to connect unexcited generator to the tires 3 MSB through limiting reactor 82; b) connected to the same busbar 3 MSB capacitor battery 84 through contactless thyristor switch 85 in the optimal phase voltage; a switch device 26.2 damping of the magnetic field generator 1.2 him winding 27.2 excitation on his automatic regulator 33.2 excitation. In the synchronizing circuit formed by the anchor windings of generators 1.1, 1.2 and limiting reactor 82, there is a surge surge current. The value of this current with inductive limit resistance limiting reactor 82 to valid values. Surge current generator 1. measure the current transformer 86.2 its ARV 33.2 and use it to send a forced current in the winding 27.2 excitation of the generator, providing rapid rise of the voltage generator 1.2. Thus on its shaft creates a forced synchronization electromagnetic torque, and through it draw the rotor (not shown) of the generator 1.2 in synchronous rotation with the rotor (not shown) of the generator 1.1 working SDG. The capacitor Bank 84, connected to the terminals of the running generator 1.1, compensate the capacitive current of the inductive surge current generator 1.1, lower than the value of the failure of the voltage at the terminals of the generator and the tire 3 MSB. With exposure time of about 0.5 s, the signal "zero"generated output "e" block 40.2 control the Executive bodies of self-synchronization, capacitor battery 84 is turned off. Even after 0.5 unit signals generated at the outputs of the "W" and "e" block 40.2 control the Executive bodies of self-synchronization, include generator switch 4.2 and re - condensing the battery 84. Is again an inductive surge surge current in the circuit synchronization, which at this point is excluded automatically limiting reactor 82, re-payment of this current capacitive current of the capacitor Bank 84 and repeated forcing of the excitation current of the generator 1.2 by current transformer 86.2. As a result, the rotor of the generator 1.2 is finally in synchronism about what to wear to the rotor working generator 1.1 SDK. Zero signal sent NC block contact (not shown) of the switch 4.2 input "C" block 40.2 control the Executive bodies of self-synchronization, remove power from the device, thereby unlock the auxiliary contact 83.2 circuit limiting reactor 82 off and re-condensing the battery 84. Routine connection of the generator to the tires 3 MSB on this end.

Then either load a single working SDG2: 1.2-2.2, either enter it in the mode of parallel operation with working SDG: 1.1-2.1.

3. Management of SDG in stand-alone (single) working mode

After you enable SDG2 to the de-energized bus of its load by alternately connecting the receivers of electric energy (not shown) to the tires 3 MSB. Growing workload measure, in particular, by a sensor 50.2 active current (figure 2) trichinoscope (combined) e-SOPS-regulator 39.2 fuel and air. In this case the changes of static and dynamic loads SDG2 the controller react automatically in different ways.

With a sudden surge capacity large receiver, called perturbation, form signals through such trichinoscope (combined) e-SOPS-regulator 39.2 fuel and air, which creates, in particular, high-speed signals nature is the communication load: U 1=f1(Δ) - at the output of its comparator 51.2 load, and U2=f2(dP/dt) is the output of its sensor 50.2 active current, which appear respectively at the outputs "I" and "II" of this EDP control. These signals act synchronously: the first signal to the servo motor 31.2 monopulse mekhanogidravlicheskijj centrifugal regulator 30.2 fuel supply, and the second signal on the system 23.2 control static semiconductor Converter 22.2 reversible synchronous electric machine 21.2. Increment load Δ defined as the difference of signals of a given capacity and the current load SDG2: Δ=Pass-P2. The signal Rassform in block 41 parallel operation, in particular, the integrator 58 as the sum of the average signal power Pcfthat measure, in particular, the sensor 55 average load, and signal Δf of the frequency deviation of the current network (it is obtained as the difference of values for a given frequency fassand the actual frequency fdcurrent network available at the output, in particular, the sensor 56 actual frequency), which is formed by the comparator 57 frequency current.

In this regard, servo 31.2 monopulse mekhanogidravlicheskijj centrifugal regulator 30.2 angular velocity, kinematically connected with the fuel rail 48.2 injection pump (not shown), force feeds the fuel. Fuel rail while moving the slider of the potentiometer 49.2, which repeteur signal derived dP/dt, previously came with the release of "II" on the system 23.2 control. Acting last on SPP 22.2 increase with some anticipation (due to the greater inertia TKN 20.2) the voltage at the terminals of OEM 27.2, its torque and the rotational speed of the turbocharger 20.2 boost. By improving the productivity of the latter, increase synchronously and consistently induced fuel pressure charge air. Get complete combustion without smoke exhaust and with a low content of harmful products of combustion. This consistency and synchronicity of these two operations make it possible to increase the degree of force fuel corresponding setting trichinoscope e-SOPS-controller. Due to the greater degree of force feeding a combustible mixture and better combustion (oxidation) of the fuel vapors receive greater increment torque diesel and more rapid response to the perturbation. The quality indicators power - failure frequency and time of recovery - due to this improve.

With increasing static load on SDG2 parameters of exhaust gases of diesel mass, temperature, pressure increase. Changing the composition e is their gas - the declining share of factions forming soot. Due to this increase the torque developed utilizing a gas turbine 19.2 turbocharger 20.2 boost. In these conditions not to overdose the supply of charging air into the combustion chamber, simultaneously reduce the torque produced by OEM 21.2 in the mode of its operation of the driving motor, inversely proportional to the increase in static load on SDG2. For this purpose the end of the transition period caused by the load and controlled, in particular, the delay elements 80.2, SOPS regulator 39.2 measure, in particular, the static component of the current capacity of the P2generator 1.2 by dutchie 50.2 active current of this trichinoscope e-SOPS-controller, determine its output "III" the value of the signal U3=f3(R2, influence them on the system 23.2 management WBS 22.2, lowering the voltage at the terminals of OEM 21.2 reduce due to this, its torque and set the value of the rotational speed of the turbocharger 20.2, which receive the optimum mixing ratio "fuel-air" for the current static load.

When static load SDG2 becomes equal to approximately 50% of nominal, the gas turbine 19.2 turbocharger 20.2 able to provide the demand of diesel in naduvath is m the air, and when you load SDG more than 50% of the nominal, its performance becomes excessive. To maintain the optimum ratio of the combustible mixture "fuel-air" and in this range of static loads SDG2, measure the load current of OEM 21.2 by a sensor (not shown) idle signal which is sent to the system 23.2 management WBS 22.2. When the current ASAM zero NGN switches in inverter mode, resulting in osem 21.2 transferred from the motor in the generator mode. From this moment, due to the change of sign of the magnetic moment of osem with the motor on the brake, the shaft of the turbocharger 20.2 boost slow down and set the desired performance from him. Electricity produced by OEM 21.2 in generator mode by utilizing an excess of exhaust gases of a diesel engine 2.2, refer to the electrical network on its staff the food chain, matching the frequency of the current, OEM 21.2 and the main generator 1.2 by SPP 22.2. Thanks to the utilization side heat exhaust gases into electrical energy increase efficiency SDG2.

With a sudden surge capacity large end user in the range of static loads SDG more than 50% of the nominal signal U2=f2(dP2/dt) dynamic increment of load effect with some pre-emption system 23.2 control staticscoordinating Converter 22.2 OEM 21.2. Another signal U1=f1(Δ) increments the static load generated, in particular, the comparator 51.2 load trichinoscope (combined) e-SOPS-regulator 39.2 and sent to the amplifier, in particular, 52.2 and further to the servo motor 31.2, which, by moving the fuel rail 48.2, increase the fuel supply. Simultaneously, the fuel rail is rotated through its slider of potentiometer 49.2, continues to affect the system 25.2 management WBS 22.2 in the same direction as the signal U2=f2(dP/dt) and coordinated simultaneously increase the pressure charge air due to the fact that this system reduces the current OEM 21.2 operating in generator mode, reducing its electromagnetic braking torque than the uplift of the rotational speed of the turbocharger 20.2 charge and its performance. At the end of the transition period taking load the main synchronous generator 1.2, signal increment its static load U3=f3(R2)formed trichinosis (combined) e-SOPS-regulator 39.2 output "III" and directed to the same Executive bodies of osem again increase the current generator load last and develop its capacity in excess of its value in the previous static mode. This is because after p is IEMA diesel generator 1.2-2.2 additional load weight, the temperature and pressure of his excess (waste energy) of the exhaust gas increases.

When static load SDG2 will be equal to 80% of nominal, in the particular case of the method, the comparator 79.2 load (figure 2)that is configured to actuate when the set point is 80% of rated power, trichinoscope (combined) e-SOPS-regulator 39.2 form at its output a "V" signal maximum permissible load Psupplementary makwhich is sent (arrow "b") in the subsystem 43 top-level management (figure 1). The latter forms known algorithm command on the commissioning of additional generating units, for example, SDG, which sends its subsystem 34.1 DAU. This subsystem shall enter into effect SDG in the sequence described above.

Figure 6 shows another example of a method of forming the same signal maximum permissible load Psupplementary makby means of the comparator 79 average load unit 41 parallel operation, is configured to actuate when the set point is 80% of rated power. When it is triggered, the signal is sent in the direction of arrow "b" in the same subsystem 43 top-level management. In this example, the total number of Comparators load setpoint 80% is reduced to one, as in the composition rahimullah (combined) electronic the electronic SOPS-regulators 39.1 and 39.2 they are no longer required.

A similar command on the commissioning of additional SDG send (regardless of the current load operating SDG) on such criteria control power, increased reliability of power supply of the object and the maximum reliability of its power supply. Management criteria set either by switch 47 (Fig 1) criteria control power on control panel 44, or modify the software automatically block parallel operation 41 in accordance with the current operating conditions of the power plant. The switch 47 has four positions, which correspond to the four criteria management: economic (position "1"), high reliability of power supply (position "2"), maximum reliability of power supply (position "3") and environmental (position "4").

4. Management of synchronous diesel generators in parallel operation under different management criteria

Upon completion of the reactor-condenser self-synchronization optional input SDG, for example SDH, proceed to the distribution of active load in accordance with a specified criterion control power while maintaining a given frequency (figure 2).

When economic criteria (switch 47 is in position "1") synchronous diesel generator is the ora operate at a minimum fuel consumption, the minimum emissions of carbon dioxide (greenhouse) gas and at least work on their service. For example, if the power supply is a vessel, this criterion prescribed for the course in the open sea under normal weather and navigation conditions. This criterion corresponds to the lowest under the current conditions, the number of working Sdhow that load on (75-80) % of rated power, when they work with the best efficiency. With increasing load SDG to Psupplementary makintroduce additional SDG using trichinosis (combined) EDP-encoder subsystem top level management and the DOW and the unit of parallel work. In particular, the sensor 55 medium loading unit 41 parallel operation determines the current average load on one SDG, which immediately after entering the additional unit will be about 40% of its rated capacity. Conditions of fuel combustion at such loading becomes even worse when combined boost. Therefore, the signal, in particular, comparator 60 load unit 41, configured to actuate at an average load of 40% of rated power, included, in particular, the intermediate relay 63, which translate trichinosis (combined) e-SOPS-regulators 39.1 (not shown) and 39.2 fuel and air respectively SDG and SDG2 on the criterion of control, aimed at minimization of carbon formation in the exhaust duct. This corresponds to a periodically changing the distribution of loads between the SDG in relation to 60% on 20% of their nominal capacity.

This operation is done at the expense of, in particular, a partial bypass of the adjusting resistors 77 and 78 of the settings in the block 41 parallel operation through contacts time relay 70 and 71 operating mode pulse-pairs, which starts when the intermediate relay 63. Thus the Comparators 51.1 and 51.2 load in rahimullah (combined) e-SOPS-regulators 39.1 and 39.2 send signals Rsad(60%) > Rsad(20%). After a predetermined time delay in the relay 70, for example, 30 minutes, the correlation between this distribution change on the back, and after another 30 minutes back to the old at the expense of time relay 71, after which the cycle is repeated. In this mode alternating levels of load Sdhow their combustion chambers are self-cleaning (burnout of soot) in the period when SDG loaded to 60% of its rated capacity. In this sub-criterion of concurrency control SDG minimizing the number of masochistic and cleansing gas turbines TKN, and also decreases the probability of ignition of soot in their exhaust tracts and burning.

When the average load on the potions generator will increase to 50% of the nominal proportion of the change in the ratio of 70% to 30% due in particular, the comparator 61 average load, intermediate relays 64 and time relay 72 and 73. When the comparator 60 average load of 40%, and the relay 63, 70 and 71 are turned off.

With the increase of the average load on the SDG to 60% of rated power, go to the office for the sub-criterion maximum dynamic stability of parallel operation Sdhow, which corresponds to a uniform distribution of the total load power between units. This operation is performed, in particular, the comparator 62 average load and intermediate relay 65, which shut down other Comparators 63 and 64 average load and fully continuum adjusting resistors 77 and 78 of the setpoint and therefore the Comparators 51.1 and 51.2 loads rahimullah (combined) EDP controls the flow of fuel and air to send the same signals Rsad=Psad.

For ship SDG tolerance in the accuracy of the distribution capacity in the range of average load of 40% Rnand less increase with ± 15% (the requirement of the Rules of the Russian Maritime register of shipping (RMRS) for objects of the marine infrastructure) up to ± 20% of rated power SDG, when Rcf≥ 50% Pnthe error is automatically reduced to ± 10% of rated power, and when Rcf≥ 60% Rnthe error is set equal to ± 15% of nominal, is it required by the Rules RMRS under uniform load distribution. Moreover, the transition to the regulation accuracy of 20% is dictated by the need to reduce tension work servomotors 31.1 and 31.2 monopulse mekhanogidravlicheskijj CRF and save their relatively small share in the interaction with trichinosis (combined) e-SOPS-regulators of fuel and air, and reduction of error up to 10% is intended to limit the number of additional runs SDG signal Radditional poppyduring their work with a load of 70% of rated power, than also save the resources of the latter. Program regulation tolerances perform intermediate relays 63, 64 and 65 which different continuum, in particular, the adjusting resistors 81.1 and 81.2 and change their bias voltages at the inputs of amplifiers 52.1 and 52.2 rahimullah (combined) e-SOPS-regulators 39.1 and 39.2 fuel and air.

When running parallel operation Sdhow, one of which is in the worst condition, by economic criterion of the more worn-out diesel generator load due to the block 41 parallel operation (and the interaction of the latter with trichinosis (combined) e-SOPS-regulators 39.1 and 39.2, respectively SDG and SDG2) such power that he can develop at a given frequency (angular velocity), and the steel current load power is transferred to the more technically serviceable unit. This routine is performed in the following sequence. In particular, the switch 66 technical condition of the synchronous diesel generators unit 41 parallel operation set in one of the end positions, pointing to a worn diesel generator, for example, for SDG - position "1". These include, in particular, the relay technical condition 67 and the auxiliary relay 69. Through normally closed relay contact 67 is disconnected from the worn SDG amplifier 52.1 (figure 2 it is not shown) by a servo motor 31.1 his monopulse mekhanogidravlicheskijj CRF 30.1. Thus SDG transferred to the static regulatory frequency response 7 (figure 3). One closing contact of the relay 67 (2) continuum fully adjusting resistor 78 settings, while others connect the output of the sensor 50.1 active current worn SDG through the auxiliary contact 42.1 (not shown) to the input, in particular, the differentiating unit 59 unit 41 parallel operation. Changeover contact auxiliary relay 69 entrance, in particular, the integrator 58 of the same block switch on the output of the differentiating device 59. Now in the integrator 58 signals summed signal UΔfthe frequency deviation of the current network signal calculated the difference between the total load of the whole plant, obtained by the adder 54 signals active power, and the current load and worn SDG. That is, at the output of the integrator 58 signal receive signal U58=UΔf+(U∑P-UP1)which is sent when shunted by the resistor 78 to the input of the comparator 51.2 working load generator SDG2 as Seagal specifies the power Pass. Thanks to provide healthy SDG2 on a static regulatory feature 2 (figure 3). Then hand the effect on the servo motor 31.1 (2) worn-out SDG provide an offset of the regulatory frequency characteristics 1 (figure 3) in the correct position for its potential load P1=const. From that moment on diesel generator SDG develops at a given frequency fnonly this power and the load power plants perceive operable unit SDG2:P21,P22,P23etc. If worn will be another unit - SDG2, the switch 66 of the technical condition of the block 41 parallel operation is switched to the position "2", giving food, in particular, the relay 68 technical condition and the auxiliary relay 69. They act the same way and through the relay 67 and 69, but only in relation to SDG2.

At lower average load parallel SDG, in the particular case, to 35% of rated power or less (under economic and environmental criteria control power) operation of generating units becomes uneconomical due to the high specific fuel consumption and wastage of life SDG, as well as environmentally unfriendly because of the incomplete combustion of the fuel. At this level develop power, in particular, the comparator 93 low load (2, 6) unit of parallel work 41 that is triggered when the load of 35% of the nominal switches to a position in which its output to form a single signal sent by the arrow "g" in the subsystem 43 top-level management (figure 1). This signal this subsystem actuates known program output one of the SDG of parallel operation, for example SDG2. After turning off the generator switch 4.2 (2, 6) generator 1.2 its normally open block contact 4.2 output circuit of the comparator 93 low boot is opened, thus excluding the possibility of withdrawal from a single working SDG in the case of reducing its load to 35% of the nominal. Adjusting resistor 94 this setpoint switching of the comparator 93 a low load can be changed. Also block the Communist the tor 93 average load with 35% of rated power during the period of parallel operation of SDG and when the level of the average load to 40% of the nominal and up through intermediate relay 63 of comparator 60 unit parallel operation 41.

Control parallel operation Sdhow criteria and increased the maximum reliability of power supply of the object produced by known algorithms. Criterion reliability - position "2" of the switch 47 criteria control plant (figure 1, figure 2, 6) is used to increase the degree of responsibility of the mode of the power plant (e.g., agile mode of the vessel), and the criterion of maximum reliability of power supply position "3" of the same switch is injected during an emergency at the facility, for example, in the struggle for its life (fire, grounding, the flow of water inside the hull and so on). The load between parallel SDG under these criteria control power is distributed in proportion to their rated capacity, in the particular case equally, if the nominal capacity SDG same. This load distribution ensures the highest dynamic stability of parallel operation of LDH, which is responsible for the content of these management criteria. In these positions of the switch 47 apply power to the Executive relay 95 high reliability of power supply (2, 6), make contact of which is immediately sent to the subsystem 43 top-level control signal to start additional backup SDG. The other two trailing to what naktomi the relay 95 continuum fully in block 41 of the parallel operation of the adjusting resistors 77 and 78 of the settings. Simultaneously, the normally open contact of the actuating relay 95 off (block) all Comparators average load, with the exception of the comparator maximum load 80% of nominal. With the increase in the average load in the modified quantitative composition of the working LDH up to 80% of the nominal send the signal to enter in the following program, backup SDG. However, due to the shutdown comparator minimum allowable low boot in 35% of the nominal, the subroutine output from the parallel operation of one of the two parallel SDG block. In position "3" of the switch 47 - criterion maximum reliability of power supply of the object further include actuating relay 96, closing contacts which are connected in parallel to the button "start" 35.1 and 35.2 on the operator console 44, send commands to run all backup SDG.

When the ship is approaching the area of sailing or port of call, with a particular environmental regime, management Sdge transferred through switch 47 management criteria (position "4") on the remote control 44 operator's environmental management criterion power plant (figure 1, figure 2, 6), providing a minimum air pollution and harmful unburned combustion products: NOx, COx, SOx, HC, soot, ash, and others with whom gnlu, generated by the subsystem 43 top-level management and sent to the control subsystem (not shown) fuel system (not shown), diesel generator(s) transferred by the well-known algorithm for light, low-sulfur fuel. Simultaneously, the same signal is sent to a known standard processing engine exhaust gases (not shown) and give effect to its means (not shown) purification of these gases from sulfur, nitrogen, carbon, aldehyde and other components of the emissions. In particular, one method of reducing nitrogen compounds lower the temperature in the combustion chambers of the diesel engines. To do this, at the specified signal to increase the flow of coolant through vozduhoohladiteli 24.1 (not shown) and 24.2 charge air by known methods, for example, increase the rotational speed of the cooling pump (not shown) or include booster cooling pump (not shown). In this case, the load distribution between parallel SDG produce as well as in economic management criteria.

During normal stop SDG, for example, when the output of one of the generators of the parallel operation of the signal peak - arrow "g" in figure 1, 2 and 6 is unloaded and disconnected from the mains command subsystem DAU unit, for example SDG2, stop (after a short is idling at podsyhanii angular velocity ω PSby stop the flow of fuel through the stop device 32.2 (1) single-pulse mekhanogidravlicheskijj CRF 30.2 while stopping the supply of air from TKN 20.2 by transfer subsystem DAU 34.2 reversible synchronous electric machine 21.2 mode forced electric braking: original regenerative transmission of energy to the grid, and then dynamic by absorption of energy in the braking resistor (not shown). The simultaneous supply of fuel and air increases the reliability and speeds up the process of stopping the diesel 2.2, and also eliminates long free run TKN 19.2-20.2 in the absence of pressure in the lubricating system stopped diesel and hung oil precachemodel pump 5.2. In this part of the kinetic energy of rotating mass that TKN and its Osam use useful in receivers outlet.

When receiving from a sensor (not shown) in the subsystem 34.2 DAU working SDG2 signal critical failure, for example, the spacing of the diesel generator circuit breakers 4.2 synchronous generator 2.2 send without time delay signal off the faulty generator without unloading, and then immediately send a stop device 32.2 monopulse mekhanogidravlicheskijj CRF 30.2 signal pre is the treatment of the fuel, and also the stop signal TKN forced by electric braking, OEM 21.2 through its management system 23.2 static semiconductor Converter 22.2. Simultaneously block the subroutine start subsystem DAU. If within 60 with angular velocity SDG2 is below ωminsubsystem 34.2 DAU send the bodies of the alarm (not shown), the signal "SDG does not stop". Simultaneously closed by the damper (not shown) an air path on the suction pipe of the turbocharger 20.2. A similar routine protection perform and when you click 36.2 remote emergency stop on the control panel 44 of the operator.

With a sudden and complete breakdown of the tire 3 MSB (mode, "black out"the signal "zero"appearing on the output of the sensor 45 voltage (figure 1) and coming (along arrow "a") for the subsystem 43 top-level management, form the last command to run for unemployed SDG independent power group ANN 10 and the opening of the controlled shut-off valves 11, 12, 13 and 14 on its suction and discharge nozzles. Independent group ANN 10, fed by voltage emergency source, such as rechargeable batteries, produce continuous pumping of two prescribed to start backup SDG, for example SDG and SDG2. Simultaneously with this the m subsystem 43 top-level control form teams run these SDG, sent subsystem 34.1 and 34.2 DAU these synchronous diesel generators. In this case, the subsystem DAU in SDG, which is "on duty", for example, at 34.2 SDG2, immediately perform routine pnevmaticheskogo start and acceleration TKN 20.2 through OEM 21.2 supplied from the emergency source (not shown). When this SDG2 will set the angular velocity ω=ω1and will come into effect NNN 5.2 operated shut-off valves 12 and 14 on the piping macroprolactin SDG2 from an independent group ANN 10 close and continue the acceleration of 2.2 diesel fuel through optical mekhanogidravlicheskijj CRF 30.2 to polisindromnoe angular velocity ωPS. When this angular velocity generator 1.2 excite through block 40.2 control the Executive bodies of self-synchronization (as described above), and also due to the device 26.2 damping of the magnetic field generator and, in particular, contactor 87.2 bias (figure 4). When the voltage of this generator, as measured by the sensor 46.2, to the value equal to 85% of nominal, include its generator breaker 4.2 and switch power independent group ANN 10, and OEM 27.2 on the main power source (not shown).

In cold SDG that is not "on duty"while maloprodaja independent group ANN 10 (IG) blow his posovszky piping and cylinders through a system of compressed air and blow-off valve (not shown), after raising the pressure of lubricating oil to the specified starting values start to execute the subsystem 34.1 DAU turning the crankshaft of the diesel engine is described by, followed immediately produce his first start working through pnev-Mostrar 15.1 (not shown) and the acceleration TKN 20.1 (not shown) through OEM 21.1 (not shown)as described above when it is powered tire 3 MSB. After increasing the angular velocity of 2.7 diesel SDG to intermediate values of ω=ω1in which it is being translated into NNN 5.1, independent group ANN 10 stop, shut-off and control valves 11 and 13 are closed. Next diesel 2.1 SDG dispersed on fuel due monopulse mekhanogidravlicheskijj CRF 30.1 (not shown) to podsyhanii angular velocity ωPSit is running for some time idling to warm up and enter operating parameters in norm. After setting the temperature fresh water cooling and lubricating oil specified values, the command subsystem 34.1 DAU sent in block 40.1 (4) control the Executive bodies of self-synchronization, perform the last program of the reactor-condenser self-synchronization, as shown above, which completes the connection of the generator 1.1 SDK to the mains via its generator breaker 4.1.

If in case of a tire 3 G Is O none of the units is not set to "on duty" SDG and the pressure of lubricating oil is not in the lubrication systems of all reserve units, the subsystem 43 top-level management also include for continuous operation independent of the power supply from the emergency source group ANN 10, open controlled shut-off valves 11, 12, 13 and 14 and raises the pressure of lubricating oil directly from the two reserve units, for example, SDG and SDG2. Simultaneously blow pulkovoalonya pipelines and cylinders of both engines due to the compressed air system and purge valves (not shown). The SDG, in which the pressure of lubricating oil will rise to a given starting values of the first, for example, SDG2, start by means of its subsystems 34.2 DAU operation turning the crankshaft and start the diesel 2.2 by pnevmostartery 15.2, and TKN 20.2 through OEM 21.2 supplied from the emergency source. When the angular velocity of this SDG2 after switching on fuel will increase to podsyhanii ωPShis excite through block 40.2 control the Executive bodies of self-synchronization, as described above. After restoring the voltage of this generator up to 85% of nominal, include its generator breaker 4.2 and switch power independent group ANN 10, and OEM 21.2 on the main power source (not shown).

Operation turning the crankshaft and start the diesel 2.1 through pnevmostartery 15.1 (not showing the other cold backup units SDG, and also to disperse his TKN 20.1 (not shown) through OEM 21.1 (not shown) from the emergency power source start immediately after dispersal SDG2 to an intermediate angular velocity ω=ω1and transfer it to the fuel. (Due to time-shift the phases of the compressed air on pnevmostartery 75.7 (not shown) and 15.2 run SDG and SDG2 saves compressed air consumption in the absence of power in the mains). After the successful launch of cold SDG up under synchronous angular velocity ωPShis warm up by idling, smokingrelated through block 40.1 (not shown) control the Executive bodies of self-synchronization and is connected to bus 3 MSB through the generator circuit breaker 4.1 (not shown), as described above.

If in the "black out" the work of the independent power group ANN 10 (1), osem is impossible (faulty ANN 10, refusal or absence of the emergency source (not shown), in the process of running two backup synchronous diesel generators, for example SDG and SDG2, one of which, for example SDG2 is "on duty", the start-prepared ("duty") SDG2 (2.2) and TKN 20.2 produce using traditional free turbocharging, i.e. without participation of OEM 21.2, and pre-maloprodaja unprepared synchronous diesel generator is ora SDG (2.7) hung produce oil Sipper pump 5.2 "on duty" synchronous diesel generator 2.2 after its dispersal pneumatical starter 15.2 to an intermediate angular velocity ω 1. With this purpose, the sensor signal (not shown) of the angular velocity SDG2 subsystem 43 top-level management managed open shut-off valves 6 and 7 and produce a pre-flow lubrication system unprepared diesel 2.1 by hung oil Sipper pump 5.2 running a "duty" synchronous diesel generator 2.2. After the angular velocity unprepared SDG 2.1 reaches intermediate values of ω1, pumping its oil is transferred automatically on its own oil Sipper pump 5.1 and operated shut-off valves 6 and 7 are closed. This allows program execution output power and mains supply from the de-energized state even without the use of an independent power group ANN 10, thus increasing the survivability of the system of automated control of SDG. The launch unprepared SDG 2.1 its pneumatical starter 15.1 (not shown) made in the mode of combined turbo, i.e. with the participation of its OEM 21.1 (not shown), as described above, since this point in time the power to the main switchboard of the 3 will be restored soon after you connect to a "duty" SDG2 (2.2).

If you want to run separate pumping systems lubrication of any backup diesel generator, for example SDG2: 1.2-2.2, by one not Anisimova nutrition group AMPN choose 10 through switch 37 ways lubrication Sdhow the regime of separate pumping SDG2 from independent power group ANN 10, then switch 38.2 remote control, available respectively at each SDG on the panel 44 of the operator, include for continuous operation independent power group ANN 10 and open simultaneously operated shut-off valves 12 and 14 from its suction and discharge pipes, respectively. Turn off independent power group ANN 10 the same switch 38.2 remote control or automatically by subsystem 34.2 DAU after commissioning of the hinged produced pump 5.2 of this SDG2.

The method of automated control of synchronous diesel generator, namely, that in maintenance mode "on duty" ready to start synchronous diesel generator is heated by diesel pumping heated fresh water through his zerobalance space and cooling thermostat fresh water and pumps the heated lubricating oil through the oil thermostat and oil system of diesel engine, and these operations are performed by the program signals subsystem remote automated control of "on duty" synchronous diesel generator, when receiving the starting command "on duty" synchronous diesel generator checks if the pressure of lubricating oil to the specified value, produce three working start the diesel engine by feeding on pneumatical starter inrush of air at normal pressure, alternating attempts to start pauses between them, increasing the angular speed of the diesel engine to the preset value ωminautomatically injected into the combustion chambers of the diesel fuel through optical mekhanogidravlicheskijj centrifugal regulator angular velocity and the fuel high-pressure pump and dispersed together on diesel fuel and pneumatical starter to set intermediate values of the angular velocity ω1at which time simultaneously off pneumatical starter and switch lubrication system on its hinged produced pump, then dispersed diesel fuel through its optical mekhanogidravlicheskijj centrifugal regulator angular velocity excited synchronous generator through its excitation regulator, and at the steady state angular velocity of the unit, equal podinkrasnim value ωPSmake a short exposure time, by entering operating parameters of the diesel engine to normal, when the voltage of the generator is equal to 85% of nominal, and the corresponding angular speed diesel perform routine synchronization excited generator is running synchronous generator include synchronous generator to the grid by the generator switch, automatically exp is univelt through excitation regulator relative to the reactive load generators, and relative active load diesel generators P1and R2by monopulse mekhanogidravlicheskijj centrifugal regulators angular velocity or translate active load fully entered synchronous diesel generator in case of replacement of units during the period of this change upon reduction of the active load on the output unit to the minimum allowable it is disconnected from the electrical network by the generator breaker, reduce the angular speed by the servo motor to podsinivanija values ofώpwith a,which is operated within the prescribed time, then stop the supply of fuel through the stop device monopulse mekhanogidravlicheskijj centrifugal regulator angular velocity, and when the parallel operation of diesel generators active load P1and R2support the specified distributed through the actions of their optical mekhanogidravlicheskijj centrifugal regulators angular velocity, the regulatory characteristics of which are respectively set, and upon receipt of a running diesel generator critical alarm has been shut down by subsystem remote is wow automated control without the prior unloading diesel generator, generator circuit breakers, stop by diesel stop-optical device mekhanogidravlicheskijj centrifugal regulator angular velocity and block routine run, and if the angular velocity of 60 seconds will not be belowώmin,include alarm system stop and block the air intake, turbocharger boost through the damper, and the sudden disappearance of voltage in the mains pumping lubricating oil before starting unprepared diesel generator shall be implemented by independent on nutrition Autonomous electric oil Sipper pump, characterized in that in maintenance mode "on duty" ready to start command subsystem remote automated control of lubrication diesel "on duty" synchronous diesel generator produces a continuous heated oil through the oil system directly working synchronous diesel generator through its controlled shut-off and butterfly valves and pipelines, equipped her for this, in addition produce periodic cranking its crankshaft through pnevmostartery at reduced pressure of the compressed air and eroticheskoe drainage pustovojtenko pipeline and cylinder diesel from condensing moisture through the starting system of compressed air and blow-off valve, razvorujut generator through the damping device of the magnetic field, and temperature of the pumped lubricating oil and fresh water through their thermostats produced in accordance with software-defined subsystem remote automated control values calculated it based on measurements of environmental parameters, while when there is absence of necessity in the production of the "duty" of one of the synchronous diesel generators in current mode controlled shutoff valves on the oil system working synchronous diesel generator from all reserve units close; when you receive the command to run, including by increasing the working load of the generator set to the specified limit, in addition to checking the pressure in the lubrication system "on duty" diesel generator, test the temperature of the air in the engine compartment and the absence of excitation of the running generator, when the air temperature in the engine compartment less valid continuum the air cooler charge air its diesel by-pass valve and simultaneously with the first enable pnevmostartery at the normal operating pressure at the start of the unexcited synchronous diesel generator produce acceleration and it is turbocharger boost through its reversible synchronous electric machine in the mode of a drive motor without interruption of its work during a possible starter pauses in the air, in this case, the rotational speed of the turbocharger boost is set such that the value of the coefficient of excess air in the combustion chambers are launching a diesel corresponded to starting the flow of injected enriched fuel-air mixture;

FIELD: electricity.

SUBSTANCE: invention is attributed to the field of electric engineering and can be used for improving dynamic stability of electric-power systems and for damping electromechanical vibrations of generator rotor. In the method for improving dynamic stability and vibrations damping, alternating current synchronous generator rotor speed is monitored and synchronous generator rotor speed is lowered after insertion disturbance into system up to the rotation rate of magnetic field by means of mechanical deceleration of mentioned generator rotor. Electromagnetic brake is mechanically linked with generator rotor and prime mover rotor via clutches, voltage on generator terminals and generator stator current is continuously measured by which parameters the generator electromagnetic power is determined. This power is compared with electromagnetic power value which existed before insertion of disturbance. When result of power comparison exceeds predefined value, control signal for electromagnetic brake switching on is generated. The value of decelerating torque is determined by difference between values of the measured electromagnetic power and the electromagnetic power which existed before disturbance insertion, and duration of decelerating torque application is determined by change in generator rotor speed. To do this the generator rotor speed after disturbance insertion is determined and compared with the value which existed before disturbance insertion. Electromagnetic brake is switched off when equality of current rotor speed and rotor speed in mode before disturbance is reached and when measured power is equal to the power which existed before disturbance insertion.

EFFECT: dynamic stability of electric-power system improvement and providing damping of electric-power system electromechanical vibrations.
