FIELD: engine building.
SUBSTANCE: invention relates to gas turbine engine building and can be used in automatic control systems of gas turbine engines used in gas turbine units for electric generators drive. In the known method of control of the turbine generator, which consists in the fact that the specified rotor speed of the turbine generator is generated, the turbine generator rotor rpm is measured, maintaining specified value of rotor speed of turbine generator by changing mechanical power of turbine and measuring current electric power of generator, according to the present invention, depending on the speed of the turbo generator rotor rpm controller, a threshold is selected based on the rate of change of electric power of the generator and the time interval required to compensation the change in electric power of the generator, generating the generator electric power variation speed signal and if the said signal is exceeded by the absolute value of the selected threshold, the speed of the rotor speed controller of the turbine generator is increased during the selected time interval. Proposed control method allows reducing rotation speed deviation from rated value approximately by 1.5 times and reducing time of transient process by two or more times.
EFFECT: higher accuracy of turbo generator rotor speed regulation in transient modes.
