The method effects control upon engines, in particular to regulating power of a gas-turbine-generator system used in gas-turbine locomotives, hybrid locomotives, etc. A control signal for the fuel metering unit actuator is formed by an electronic engine control system on the basis of processing of a signal from a turbine rpm sensor and a design value of the generator active electric output power. The system power can be preset. A preset power value is compared to a real power calculated value which is obtained according to measured values of current and voltage. An obtained difference is taken as the basis for forming a control signal for the fuel metering unit actuator in order to provide a certain turbine rpm and a control signal for a current regulator supplying energy to the generator excitation winding in accordance with the load curve of the gas turbine-generator system.
