FIELD: engines and pumps.
SUBSTANCE: invention may be used in gas turbine engine ACS electronic circuitry. Said gas turbine engines have free turbine and are operated integrated with gas turbine units to drive electric generators of gas turbine electric power stations. In response to signal of high-voltage switch actuation free turbine rpm is increased to 105% as well as fuel flow rate controlled by acceleration control unit unless measured free turbine rpm reaches 105%. Then, signal is generated to actuate said switch to reduce fuel flow rate unless free turbine measured rpm decreases to 100% and to keep up said rpm by appropriate fuel flow rate variation.
EFFECT: higher efficiency of electric power station thanks to higher quality of ACS operation.
