FIELD: engines and pumps.
SUBSTANCE: proposed method comprises measuring turbo compressor rotor rpm ntc and acceleration n°tc, measuring air temperature at turbo compressor inlet Tin* , calculating turbo compressor rotor rpm ntc rd reduced to turbo compressor inlet air temperature, shaping acceleration by two preset relationships for acceleration and throttling, respectively. Besides generator load cut-on signal is introduced. In case there is no generator load cut-on signal and there is acceleration signal 1=1, acceleration is shaped by preset relationship Fuel feed into combustion chamber is performed proceeding from said three relationships.
EFFECT: reduced possibility of compressor unstable operation and turbine overheating.
