System to control mechanical plant of vessel

FIELD: transportation.

SUBSTANCE: system to control a mechanical plant of a vessel comprises two autonomous lines to control engines of the right and left boards accordingly. The autonomous control line comprises a setting control unit, a control unit, logical elements OR, AND and NOT, three amplifiers, main and auxiliary electrohydraulic converters of channels "more" and "less", accordingly, an actuating mechanism with a control lever, an end switch of idle run, an electromagnet of emergency engine shutdown, a feedback sensor connected in a certain manner.

EFFECT: emergency-free operation of vessel engines.

FIELD: power engineering.

SUBSTANCE: data on the state and IEPS parameters and that on screw propeller drive and other consumers and ship navigation conditions are processed to calculate forecast load variation. Starting including forestalling, outage and actuation for parallel operation of generators are controlled with die allowance for their required quantity sufficient for supporting of IEPS operation, ship motion control parameters and navigation conditions. Minor consumers ON/OFF control is executed to ensure the efficient operation of generator units and higher quality of supply voltage. Dynamics of acceleration and deceleration of screw propeller and its drive is controlled subject to ship motion, navigation conditions, current and forecast electric power and quality parameters. Dynamics of turn of steering house, if any, is controlled depending on generated and forecast power of generator units.

EFFECT: fuel savings, fast response and manoeuvrability, higher energy quality.

SUBSTANCE: invention relates to ship building, particularly, to control systems for propulsors including those with adjustable-pitch screw, jet propellers with reversing steering device consisting of rudders and rums, and vane propellers. Control system comprises setting device, comparator, two amplifiers, working fluid constant-flow rate slide valve and device to vary rate of working fluid feed into actuator. Besides, system additionally incorporates device to load turn angle variation rate.

EFFECT: reliable control over turn angle variation rate.

SUBSTANCE: power plant is controlled by preset travel speed and conditions setters. The latter generate signals on defining rated travel speed and power plant output in running along preset route. Parametres defining response of power plant to preset magnitudes of controlled parametres, serviceability, operating conditions and power plant actual state are estimated. Results of the analysis allows configuring power plant and calculating preset magnitudes of controlled parametres. Parametres are corrected with respect to actual vehicle speed. Then they are optimised allowing for response of power plant to preset magnitudes of controlled parametres, serviceability, operating conditions and power plant actual state. Aforesaid allowed for, optimum control effects are generated to control power plant and its actuators.

EFFECT: optimum, faultless and safe control over vehicle power plant.

SUBSTANCE: device contains magnetoelastic torque transducer consisting of two magnetoelastic converters located at opposite sides of propeller shaft and made with test coils. Transducer is capable of measuring mechanical stress caused by torsional oscillations and constant component of torque. There is compensation circuit of zero signal and automated remote control system for main engine of vessel's power plant. Apart from it, device has synchronous detector, lower frequencies filter, upper frequencies filter, and threshold devices.

EFFECT: increase of reliability and efficiency of vessel's power plant at expense of prevention of operation of diesel in sphere of mechanical stress from torsional oscillations exceeding preset value and its protection from overload.
