Description of the best embodiments of the present invention

In Fig.1, figs.2 and Fig.3 schematically automatically adjusts the hydraulic apparatus 30 that is designed to extract energy from wave movement / transformation of wave energy, which contains an axial hydraulic pump 31 having a housing 32 defining a chamber 33. Referred to the housing 32 includes a side wall 34 having an upper end, a closed top wall 35, and a lower end, a closed bottom wall 36. Mentioned bottom wall 36 is configured to attach to the base 37.

Inside the chamber 33 has a piston 38, which provides the separation chamber 33 on the rod or operating compartment 39 and a hollow compartment 40 and which is made with the possibility of sliding reciprocating movement in the chamber 33. Between the piston 38 and the side wall 34 to prevent leakage of fluid behind the piston 38 and her flowing between the working compartment 39 and a hollow compartment 40 is provided by piston seal (on the attached drawings not shown). In the ideal case due to perfect the seal between the moving piston 38 and the side wall 34 of the pump 31 operating compartment 39 and a hollow compartment 40 of the chamber 33 inside the pump 31 are not reported. As wear of the seal is allowed a flow of fluid between the two compartments of the chamber 33.

The piston 38 is attached mechanical damper 41 on the side of the working compartment 39, so that the mechanical damper 41 is located on the working compartment 39 of the chamber 33. In addition, the piston 38 is attached mechanical damper 42 on the side of the back cover 39, so that the mechanical damper 42 is located on the side of the back cover 39 to the measures 33.

From the piston 38 by passing through a hole in the upper wall 35 of the housing 32 extends the piston rod 43 mounted with the possibility of reciprocating motion of the piston 38 relative to the housing 32. In order to prevent leakage of fluid from the chamber 33 through the said hole is provided rod seal (on the attached drawings not shown).

With the upper end of the piston rod 43 is connected to the floating trigger element 44 with halyard 45.

In addition, the hydraulic apparatus 30 includes a hydraulic circuit 46 of the back cover, which includes a hollow compartment 40 of the chamber 33 and a hydraulic accumulator 47 on the side of the back compartment of the camera. Mentioned hydraulic circuit 46 of the back cover of the camera is closed, so that fluid can be exchanged between a hollow compartment 40 of the chamber 33 and a hydraulic accumulator 47 on the side of the back compartment of the camera. Mentioned hydraulic accumulator 47 on the side of the back cover of the camera is connected to a hollow compartment 40 of the chamber 33 through a flexible hose 48, so that the fluid is provided to flow between the hydraulic accumulator 47 on the side of the back compartment of the chamber and a hollow compartment 40 of the chamber 33. The hydraulic resistance of the battery 47 on the side of the back cover is the minimum always, except for a hidden zone, the cat heaven is overcome by blocking the channels of the pump using a piston snap ring.

Usually fluid in the hydraulic circuit 46 of the back cover of the camera contains a mixture of liquid and gas. A hydraulic accumulator is used simply as a reservoir and in the ideal case does not have a damping effect.

Perhaps such a solution, in which fluid in the hydraulic circuit 46 of the back compartment has a low viscosity. As in the case of many hydraulic piston accumulators, deaf compartment can be filled with a gas, such as nitrogen, to reduce hydrodynamic losses in comparison with the liquid. Another advantage of this solution is that it is economical and requires hydraulic accumulators smaller.

Perhaps such a solution, in which fluid in the hydraulic circuit 46 of the back cover has a high lubricating ability. At high lubricity fluid is provided by the extension of the service life of the piston seals. In addition, this fluid can be used to lubricate the rod seal through a capillary (on the attached drawings not shown). Lubricating fluid is required in a relatively small volume, so the associated additional costs are compensated by savings in maintenance costs and reducing downtime.

In addition, the hydraulic apparatus 30 also includes a discharge check valve 49, the connection is United with the working compartment 39 of the chamber 33 through the medium of the flexible hose 50, so for the fluid is provided by the possibility of leakage from the chamber 33 and through the mentioned exhaust check valve 49 in the direction indicated by the arrow "A". In parallel with the discharge check valve 49 and the flexible hose 50 is connected to inlet check valve 51, so that the fluid is able to flow through the aforementioned inlet check valve 51 and into the chamber 33 in the direction indicated by the arrow "B".

In parallel with the outlet non-return valve 49 is connected to a hydraulic accumulator 52 on the exit side. In parallel with the inlet check valve 51 is connected to a hydraulic accumulator 53 on the side of the entrance.

According to a variant implementation of the invention, schematically illustrated in Fig.1, a portion of the hydraulic apparatus 30 is off shore, in the water column 54 in the open sea or ocean, with the water surface 55 and the average level 56. The hydraulic pump 31 is attached to the base 37, which is installed on the seabed 57 under the water 54. Mentioned hydraulic pump 31 is attached to the base 37 for rotation relative to the base 37. In interfacing hydraulic node 58, which is also off shore, are check valves 49 and 51, as well as hydraulic accumulators 47, 52 and 53. The high output hydraulic pressure from raguseo node 58 through the high pressure pipeline is communicated with the inlet of a high pressure onshore facilities 59, and the entrance low pressure hydraulic interfacing node 58 through a low-pressure pipeline in communication with the outlet of the low pressure mentioned onshore installation.

Floating activating element 44 is in the water column 54, so that due to the wave motion of the water column and its positive buoyancy of the floating trigger element 44 follows the movement of the perturbed water, so that the floating trigger element 44 acts directed upward buoyancy force, and he, in turn, force acts on the halyard 45, which, in turn, affects in chamber 33, the piston 38, trying to pull it upwards, towards the upper wall 35 of the housing 32 of the pump. When the piston 38 moves upward, fluid in the working compartment 39 of the chamber 33 through a flexible hose 50 and the outlet check valve 49 is pushed out from the chamber 33 in the direction indicated by the letter "a" (see Fig.3).

Some of the energy of the fluid pumped through the outlet check valve 49 is stored in the hydraulic accumulator 52 on the output side, which works to reduce the fluid flow through a section of a high pressure hydraulic circuit with feedback, who are part of the exhaust check valve 49 and the hydraulic accumulator 52 on the exit side. Fluid flows through the other is part of the hydraulic circuit, and then through a separate branch of this hydraulic circuit is returned to the pump 31 in the direction indicated by the letter "b" (see Fig.3).

When the piston 38 within the chamber 33 moves upward, fluid in the hydraulic circuit 46 on the side of the deaf closed compartment through a flexible hose 48 flows from the hydraulic accumulator 47 on the side of the back cover of the camera in a remote compartment 40 of the chamber 33. Fluid in the hydraulic circuit 46 has a high lubricating capacity and low viscosity.

Mechanical damper 41 on the side of the working compartment of the camera has on the movement of the piston 38 of the damping action at the approach of the latter to the upper wall 35 of the housing 32 of the pump, thus preventing damage to the piston 38 and the housing 32 of the pump when the piston 38 upward. In particular, due to the presence of a mechanical damper 41 when the piston 38 upward reduces the shock load on the pump 31 and FAL 45.

When passing above the hydraulic unit 30 waves floating activating element 44 under the action of the weight of the piston 38 is lowered down, and the fluid is induced in a closed hydraulic circuit to the flow and is returned into the working compartment 39 of the chamber 33, passing through the inlet check valve 51 and a flexible hose 50 in the direction indicated by the letter "B". Some energy returning the fluid x is anicca in the hydraulic accumulator 53, working on smoothing the flow of fluid through a section of low pressure hydraulic circuit with feedback.

When the piston 38 within the chamber 33 is moved downward, having a high lubricating ability and low flowing fluid in the housing compartment 40 of the chamber 33 flows from the chamber 33 back into the hydraulic accumulator 47 on the side of the back compartment of the chamber through a flexible hose 48. In the ideal case, the hydraulic accumulator 47 on the side of the back cover of the camera does not have any hydraulic damping, and acts just like a tank.

Mechanical damper 42 on the side of the back cover of the camera has on the movement of the piston 38 of the damping action at the approach of the latter to the bottom wall 36 of the housing 32 of the pump, thus preventing damage to the piston 38 and the housing 32 of the pump when the piston 38 downward. In particular, due to the presence of a mechanical damper 42 when the piston 38 downward reduces the shock load on the pump 31 and FAL 45.

The cycle is repeated whenever above the hydraulic unit 30 passes the wave crest and trough of a wave.

As can be seen in Fig.2, the proposed hydraulic apparatus 30 can contain a set are arranged in a matrix of pumps 31 and floating activating elements 44 provided with mating hydraulic oslom.

In Fig.4 schematically shows a hydraulic apparatus 60 for extracting energy from wave movement / transformation of energy waves, similar to hydraulic apparatus 30. Therefore, similar elements of the hydraulic apparatus 60 and 30 have the same reference designations.

From the hydraulic apparatus 30 of the hydraulic apparatus 60 differs in that the hydraulic apparatus 60 further comprises a hydraulic accumulator 61 on the side of the working compartment, connected in parallel with the working compartment 39 of the chamber 33 through a flexible hose 50, so that a fluid medium, provided the possibility of leakage between the chamber 33 and a hydraulic accumulator 61 on the side of the working compartment of the cell.

In addition, the hydraulic apparatus 60 includes interfacing the hydraulic unit 62 includes a hydraulic accumulator 47 on the side of the back compartment of the chamber, the outlet check valve 49, the inlet check valve 51, a hydraulic accumulator 52 on the output side, a hydraulic accumulator 53 on the entrance side and a hydraulic accumulator 61 on the side of the working compartment of the cell.

Mentioned interfacing hydraulic unit 62 contains the outlet 63 and the inlet opening 64.

Operation of the hydraulic apparatus 60 is essentially identical to the operation of the hydraulic device 30, except that the hydraulic batte the tor 61 provides for piston rod 38 of the hydraulic damping during movement of the piston 38 upward, providing damping in addition to the damping effect of the mechanical damper 41 on the side of the working compartment of the cell.

Mentioned interfacing hydraulic unit 62 is located outside the shore together with the pump 31 and the floating trigger element 44 of a hydraulic apparatus 60.

In Fig.5 schematically shows a hydraulic apparatus 70 for extracting energy from wave movement / energy conversion waves containing axial hydraulic pump 71, having a housing 72 defining a chamber 73. Referred to the housing 72 has a side wall 74, which has an upper end, culminating in the top wall 75. The upper portion 76 of the side wall 74 thickness exceeds the lower portion 77 of the side wall 74 so that the upper portion 78 of chamber 73 is narrower than the lower portion 79 of the chamber 73. Referred to the upper portion 76 of the side wall 74 includes upper port 80 and the lower port 81.

Luggage 73 accommodates the piston 82, which provides the separation chamber 73 on the working compartment 83 and the hollow compartment 84 and is made with the possibility of sliding movement in both directions within the cavity 73 along it. The piston 82 has an upper section 85 and a wider lower portion 86. In contrast to the bottom portion 86 of the piston 82 of the upper section 85 of the piston 82 narrow enough to fit the top section 78 of the chamber 73, as it can be is about to see in Fig.5. On the upper periphery of the upper section 85 of the piston 82 is held in-depth edge 87. Mentioned in-depth edge 87 contains a vertical surface 88 and going downhill down the surface 89. Depth edge 87 is used to avoid complete overlap the upper port 80 of the piston 82.

Between the piston 82 and the side wall 74 is provided by the seal 90, preventing the ingress of fluid behind the piston 82 and between the working compartment 83 and a hollow compartment 84.

From the piston 82 extends the piston rod 91, which passes through a hole in the top wall 75 of the housing 72 of the pump, so that the mentioned piston rod 91 is provided to move in both directions together with the piston 82 relative to the housing 72. Also provides a seal 92 that is designed to prevent leakage of fluid from the chamber 73 through the opening in the top wall 75.

Hydraulic accumulator 93 on the side of the working compartment of the camera is connected to the top port 80 through a flexible hose 94,^that " the fluid is provided to flow in both direction between the working compartment 83 of the chamber 73 and a hydraulic accumulator 93 on the side of the working compartment of the cell.

With the lower port 81 is connected a flexible hose 95. For pressurised fluid medium, provided the conditions for exclusion from the chamber 73 through the bottom the first port 81 and a flexible hose 95 in the direction indicated by the arrow "A" (see Fig.5), and under a high pressure fluid medium, provided the conditions for admission into the chamber 73 through the lower port 81 and a flexible hose 95 in the direction indicated by the arrow "B" (see Fig.5).

Mentioned hydraulic load may include an electric generator (not shown) driven in rotation using the tangential turbine 101.

In addition, the composition of the hydraulic apparatus 100 is a hydraulic apparatus 60, which contains the hydraulic pump 31. The operation of this hydraulic pump 31 is pumping fluid through the hydraulic apparatus 100 in order to bring in the tangential movement of the turbine 101.

The composition of the hydraulic apparatus 100 also includes a hydraulic control device 102, is configured to control fluid medium pumped by pump 31 through the hydraulic apparatus 100. In particular, the aforementioned hydraulic control device 102 controls the pressure and flow of the fluid section and the high pressure is tion, section and low pressure hydraulic apparatus 100.

Hydraulic control device 102 has an inlet 103, which is communicated with the outlet 63 interfacing hydraulic node 62 through the high pressure pipeline 104. Hydraulic control device 102 has an outlet 105, which communicates with the inlet bore 106 tangential turbine 101 through the high pressure pipeline 107. The outlet 108 tangential turbine 101 is connected to the inlet hole 109 hydraulic control device 102 through a low-pressure pipeline 110. The outlet 111 of the hydraulic control device 102 is connected to the inlet hole 64 interfacing hydraulic node 62 through a low-pressure pipeline 112.

With automatically adjustable hydraulic apparatus, such as a hydraulic apparatus 100 schematically depicted in Fig.6, it can be a completely closed system of automatic control of the pump. The control algorithm is implemented to control the operation as a coastal management system, and at sea device 31 for extracting wave energy and interfacing of hydraulic node 62, the input signals of the force and the displacement of the pump, megatoplist inlet and outlet pressures of the pump to maximize output power (offset), as well as reduce shock impact while moving the pump piston up and down. This algorithm provides both increased power output of installation, and reduced wear and risk of damage to the pump 31. This approach also provides compensation tidal movements, provided that the stroke of the pump has a length sufficient to overlap the amplitude of the tide.

In response to tidal variations of the hydraulic apparatus 100 would have to keep a constant location relative to the average position of the floating activating element in the water column. This can be achieved using feedback control.

The control algorithm is adapted to the specific location and provides information about local wave mode and the tidal range and ensures optimum operation of the Converter wave energy in this place. For example, the energy Converter wave can be deployed off the coast of Western Australia, and Europe and some of the overseas territories of France. All of these places may have different amplitude tide and different statistics of wave movement. When using adapted to the specific location that was custom designed for the control algorithm provides the ability to deploy in each place the same setup and under the sea equipment in an optimal way.

In addition, this control algorithm provides the possibility of artificial control or pseudoproline buoyancy floating activating element. This can be achieved by controlling the inlet pressure of the pump for synthetic lowering physical buoyancy floating activating element 44. Thanks to this solution provides the advantage consisting in the fact that you can access (moving downwards) floating activating element 44 while smaller waves. The outlet pressure does not change the effective buoyancy of the floating activating element, but to ensure the work (moving upwards) can be controlled in a similar manner in a range of conditions excitement.

In addition, this control algorithm provides an introduction to the transfer function of the halyard some degree of hydraulic stretching". The required characteristics of the stiffness of the hydraulic apparatus 100 is usually not provided with only one mechanical tension of the halyard, and hydraulic "stretch" in order to achieve the required characteristics can be used present in the composition of the hydraulic circuit of the hydraulic accumulators.

Hydraulic apparatus 100 can provide the extraction of hidden power. To absorb some portion of the latent energy to the AI during the latent phase of the movement of the piston and delivery of this energy back into the system for subsequent absorption working agent can be used in hydraulic accumulators hydraulic apparatus 100.

Each of these signs may be attached to the hydraulic apparatus 100 individually or progressive.

In addition, each of these signs may be attached to the hydraulic apparatus or systems outside of the hydraulic apparatus for extracting energy from the motion of waves. For example, they can be attached to the hydraulic apparatus or systems outside when there are:

1) various forces acting on the hydraulic pump,

2) the possibility of damage due to limit movement of the hydraulic pump, and

3) long-term wear or leakage, which must be compensated in the system.

For example, if the turbine 148 causes the rotation of the electric generator, is connected to an electrical network, and in this electrical network failure, the hydraulic apparatus 120 can dissipate energy, and not to use it to bring in the rotation of the turbine 148. Energy can dissipate during operation of the hydraulic machine 120 to maintain a lower pressure in the chamber 123 of the pump, or through the use of the water column, in which resides the pump 31 as a heat sink and heat this water.

The controller 195 may be configured to control the operation of the outlet valve 176, inlet valve 180, pump 189 and/or valve pressure relief 186 so that the hydraulic device 160 about specials extract, the conversion or transfer of an optimal or near optimal amount of energy of motion of waves in the water column, in which resides the hydraulic apparatus 160.

The variation of the inlet and outlet pressures in the hydraulic circuit allows to provide some degree of control over the stroke. The ranges of the medium within the stroke range of the piston of the hydraulic apparatus, such as a hydraulic apparatus 160, relative to the / depending on the medium control pressure (Hsig=0.45 m, Tsig=3) / various differences between inlet and outlet pressures for a period of constant motion of the waves - see the diagrams in Fig.10. As can be seen in Fig.10, when reducing the maximum difference between inlet and outlet pressure increases the minimum value of the range of movement of the piston. These diagrams can be obtained also for other types of driving conditions of the waves.

The design of hydraulic systems / hydraulic apparatus 160 is that it is automatically adjustable hydraulic systems / hydraulic apparatus 160, which is able to supportpressure at inlet and outlet of the pump. When the pump in the hydraulic circuit puts a lot of pressure and flow rate of the fluid. The control pressure of the hydraulic circuit is carried out by two governors to what apanemi 176 and 180, one of which (namely, the exhaust valve 176 controls the outlet pressure of the pump 161 and the other (namely, the inlet valve 180 controls the pressure at the pump inlet 161. Both valve, exhaust valve 176 and the inlet valve 180 are two of the main "tools" in the hydraulic system / hydraulic apparatus 160. The management of the two control valves 176 and 180 is performed remotely with the purpose of variation of pressure for different modes of waves. In this design tangential turbine is replaced by two control valve and the heat exchanger 177 used as a means to dissipate energy generated by the pump 161. On the side of the back compartment 169 no transfer of fluid. When the expansion chamber of the pump creates a partial vacuum. If the internal leakage of fluid through the piston seals fluid is discharged through the drain hole, and through the check valve 171 is provided to prevent return of fluid back into the pump 161 when the piston 167 and the piston rod 178 in the direction of extension.

Configuration / rod hydraulic accumulator 172 on the side of the working compartment plays a key role in the optimization of hydraulic systems / hydraulic apparatus 160. By regulating the gas load and displacement hydraulic battery is atora 172 provides the ability to control power flow and dynamics of power flow. In addition, this feature automatically adjustable hydraulic systems / hydraulic apparatus 160 is that the dynamic effects similar to hydraulic shock, that is, the effects of the transfer time can be mitigated by careful control of the adjustment of the hydraulic accumulator 172 on the side of the working compartment and a hydraulic accumulator 174 on the output side and the hydraulic accumulator 182 on the inlet side. The cause of the effects of the transfer time can be rebound one or more check valves.

The pressure relief valve 186 is arranged to prevent excessive discharge pressure in the hydraulic system, a hydraulic accumulator 160.

Using check valves 171, 175, 179, 181 and 184 are provided in the correct direction (directions) flow of hydraulic fluid through the hydraulic circuit. In addition, the location of the configuration of the hydraulic accumulator just before the check valve 175 on the output side of the pump has the aim of setting of hydraulic systems / hydraulic apparatus 160 and optimization of the power output.

The flow of fluid through the hydraulic apparatus 160 can be varied between "soft" mode and "hard" mode. In "soft" mode, which corresponds to the lowest load on the pump 161, the pressure relief valve 186 is fully open, so that through the valve 186 is transferred a substantial part of the fluid. In "hard" mode, which corresponds to the highest load on the pump 161, the pressure relief valve 186 and the inlet valve 180 is fully closed and the outlet valve 176 fully.

Working power plant, which uses pumps / point wave energy Converter may be constructed from any number of blocks, number of blocks is determined by the total power output required for this power plant. Under point energy Converter wave is defined as any energy Converter wave that behaves as a single point energy absorber.

The above applies to various systems for controlling the device for extracting wave energy and optimize its operation. The above-mentioned device for extracting wave energy includes the energy Converter wave with the rise of hydraulic power, such as energy Converter wave technology SETO™, represent h the local case of the energy Converter wave. This energy Converter wave mode with feedback, i.e., is automatically adjustable. The outline of this feedback contains the output line from the device under higher pressure, and the inlet line of the fluid (the return line) under a substantially lower pressure.

Configures the mechanical stiffness by varying the volume of the hydraulic accumulator (opening/closing valves) Converter wave energy technology SETO™ WEC (short wave energy converter - energy Converter wave), including between the two extreme States of piston: squeezed and free. Under extreme squeezed state of the piston is such a position in which the piston has a minimum possibility of movement due to the fact that hydraulic fluid is restricted in movement in a hydraulic circuit to such an extent, which allows the adjustment of the hydraulic accumulator, and under extreme free condition of the piston C is followed by a session refers to the position where there was a free flow of fluid between the inlet and outlet circuits, and the piston is able to move under its own weight and the applied external force.

The above describes a system that contains a set are arranged in a matrix of wave energy Converter connected together in parallel to a common set of inlet and outlet piping, automatically forming reguliruyut is a feedback system, as explained above.

In a system containing a set are arranged in a matrix of wave energy Converter, the optimization of the algorithm And depends on the length of waves. Algorithms Andiand template Fεfundamentally different from the algorithms for the case of a single transducer wave energy. It should be noted that in the case of aggregate blocks, the difference in the algorithm in comparison with the case of a single block dominates in relation to the hydraulic interaction between the blocks.

Also described system according to the above-mentioned systems, in which algorithms Andiis generated in accordance with the approach of the optimal filter.

The response of a single point absorber - Converter wave energy, such as a unit Converter wave energy technology SETO™ can be described mathematically using power P(N,T,θ), which indicates that, in principle, the instantaneous power is a function of the instantaneous value of the wave height (H), the instantaneous values of the wave period (T) and the instantaneous angle of the length of the waves. In real sea you can have multiple lines of waves, waves from the wind, lifting waves, and possibly other components.

The function P is the instantaneous power value.

The generation of a response function R can be ostinato different ways, namely:

i) by bringing in an excited state mentioned a single transducer wave energy through a sequence of pulses of sinusoidal wave influences with a known period T and amplitude H and measuring the resulting instantaneous power P;

ii) by modeling the input signals for the power Converter waves in finite element models and/or dynamic model, which describes the output signal power as a function of these variables.

The above process can be described using three-dimensional graphs of the instantaneous power value depending on the instantaneous values of the wave period and the instantaneous wave height; this diagram is also called the "matrix of power". This matrix power describes the mechanical response of the system, which is subjected to the action of factors of the marine environment and control actions that can be applied, as described above. For a hypothetical sinusoidal wave action as a result of integrating the functions of R for time t is obtained the average value of the energy delivered at time t for a given value of the wave height and wave period.

Wave height and period real waves in the aquatic environment have temporal and spatial stochastic (bemporad cnie) variations. To characterize these variations, as well as correlations between them, are functions of the temporal and spatial distribution. The resulting distribution and the empirical models, such as the spectrum of the Pierson-Moskowitz, give the spectral distribution of wave height (wave height)2in the frequency interval in units of m2/Hz. The accuracy with which these distribution functions can describe and predict typical wave conditions in this place and at this time of year, depends on how wide the coverage can be in this place of registration of real or simulated data. The wider the coverage of observations or modeling in this place, the greater the level of statistical confidence in the predictive ability of the models derived from these data.

Statistically predicted performance in terms of output power of the Converter wave energy in this place and at this time of year is obtained from the convolution of the response of the machine (through the matrix power) and the wave model, that is, the convolution function. The total predicted energy output at time τ is obtained by integrating the function convolution in time.

If the convolution function is robust, that is, if it can be used to predict the output power with a high stat is statistical reliability, then this function can be used to optimize the response of the transducer wave energy (i.e., automatically adjusts with the feedback circuit of the hydraulic apparatus, such as a hydraulic apparatus 160, 200, 250) by applying it as an optimal filter. In the optimal filter uses knowledge of the system characteristics, and spectral characteristics of the disturbances that act on it, in this case the waves, to maximize output, in this case, the energy produced by the energy Converter of the waves.

The implementation of the optimal filter leads to the control algorithms Andiand associated control setpoints and ranges of the control specified by the function F, as described above. The technique of optimal filters allows you to create a control algorithm, which changes the controls of the energy Converter wave (described above), so that the energy output of the device over the time span t is maximized.

The method of generating optimal filter and derivative algorithms for a single location of the energy Converter wave is as follows.

i Define the matrix power P for the energy Converter wave using the method described above. Mentioned the matrix PR is dostavljati a function of the state variables of the system depending on time. Among the mentioned state variables are the pressure and flows in the output and return paths, and the pressure and volume of gas charging different hydraulic accumulators system.

ii Determine the most robust spectral model for sea state, applicable to the physical location of the transducer wave energy. Use the methods described above. It is highly likely that any location can be described using a fixed number of the prevailing sea state.

iii Produce a convolution of the spectral density of sea States using the matrix power. It should be borne in mind that there may be a natural correlation between the variables: wave height and wave period. The resulting transfer function relates produced by the facility to the state variable of the Converter wave energy, as well as to the parameters of the ocean. This function can be integrated over time to obtain the estimated mean value of the predicted output of the energy Converter wave energy at this time interval. This is an estimated value of energy is a function of the state variables of the Converter wave energy that runs the control algorithm, and the parameters of the model ocean, used to predict the spectrum of oceanic wasmus the deposits.

iv Perform multiparameter optimization of the energy function (state variables) by applying technologies vector calculus and find the local and global extrema using standard procedures such as Newton-Raphson. Experts in the field of numerical analysis and multidimensional optimization familiar with these technologies and so, under what mathematical conditions they can be applied.

v Determine the operating point and the region of stable operation in a vector space mentioned functions of energy Emax. This ensures the generation of standards F.

vi Used the control system transfer function to state variables with the purpose of generating a control algorithm A.

vii Run the model mentioned control algorithm in order to check accuracy and stability of the algorithm and sets the benchmark F.

viii is Repeated stages, starting with stage (ii), with different sea States with the goal of filling the space required control algorithms Andi. Repeat, starting from the stage (i), if this set also includes variations of the state machine.

An important feature of the development of this algorithm and its subsequent application to the energy Converter wave is that it can be done heuristic, that is, he has the ability to study: the during the lifetime of the energy Converter wave. The initial model evaluation statistics of waves in a given place can be relatively coarse, and the reliability of their predictions may be increased over time during operation of the drive wave energy, and can be built more detailed picture of the wave mode.

Referred to education is ensured by the transfer of this information back into the process of generating algorithm at stage (ii). Similarly, there is the opportunity for the heuristic process in the matrix of power, while information about the aging of the equipment going in for life and is fed back into the process of generating algorithm at stage (i). In both cases, the heuristic development leads to a more complete set of algorithms Andiand templates F to optimize energy output under all conditions encountered during the service life of the energy Converter wave.

The above reasoning and methodology applies equally to "wave farm" or a matrix of multiple wave energy Converter. The only difference is that in this scenario, you receive more state variables that are subject to regulation, because the installation is more complicated, as well as:

a) is the angular dependence, which in the matrix, the power is called protag is held,

b) the effect of the interaction between the individual wave energy Converter in the above-mentioned matrix, and

c) distribution of angles of arrival for sea States now will have to be included in the modeling of the waves.

In relation to the organization useful discussion. System optimization:

1) first, determine the matrix power;

2) then, using the matrix power and model of the waves, to design and optimize the system transfer function;

3) then, using robust spectral model for the physical location, optimize the transfer function for a particular location. Here come into play control algorithms.

This process is described by the following formula:

Waves, which actuate the hydraulic pump apparatus, are irregular input contributing factor, which means that the hydraulic pump apparatus is driven nonlinearly. Therefore, to ensure the maximization of the output power of the hydraulic system needs to be running. To control the hydraulic machine is used the optimal filter. The parameters of the hydraulic systems / hydraulic apparatus are set in accordance with the "recipe" provided by the mentioned optimal filter. This optimal filter usually will be different or modified in accordance with the location of the hydraulic apparatus, or depending on the time of year, for example, one summer, in winter the other. This optimal filter can be obtained when testing hydraulic systems / hydraulic apparatus using different parameters and/or using models. The hydraulic control apparatus in accordance with the optimal filter provides the ability to maximi the emission of energy as the area under the curve of the hydraulic power unit.
