POWER PLANT AUTOMATIC CONTROL SYSTEM Russian patent published in 2003 - IPC

FIELD: power engineering. SUBSTANCE: invention relates to automatic control of gas-turbine plants. Proposed automatic control system of power plant containing gas-turbine engine, power turbine, gas topping-up compressor turbine, gas topping-up compressor and synchronous generator with built-in automatic control system in furnished with first, second and third non-linear regulators and slave mechanism. Input of second non-linear regulator is connected with first output of gas-turbine engine, and output is connected with third input of first non-linear regulator whose first input is connected with power turbine rotor speed setter, and second input of first non-linear regulator is coupled with second output of power turbine. Output of first non-linear regulator is connected with first input of third non-linear regulator, second input of third non-linear regulator is connected with second output of gas-turbine engine, output of third non-linear regulator is connected with first input of slave mechanism, second input of slave mechanism is connected with output of gas topping-up compressor and output of slave mechanism is connected with input of gas-turbine engine. EFFECT: improved reliability of power plant in operation, provision of automatic control both at static and transient. 2 dwg
