ABSTRACT:
In an electric power generating system comprising an air compressor having inlet variable stationary blades, a fuel burner supplied with compressed air from the compressor, a gas turbine driven by combustion gas from the fuel burner, a waste heat recovery boiler for generating steam, a steam turbine driven by the steam and an electric generator driven by the gas turbine, there is provided a control system including a detector for detecting actual load of the gas turbine, a first comparator for comparing detected actual load with a load instruction for producing a difference signal, a speed/load control circuit responsive to difference between the difference signal and a signal representing a number of revolutions of the gas turbine for controlling fuel supplied to the burner, a second comparator for comparing with each other the difference signal, a signal representing temperature of gas discharged from the gas turbine and a temperature set signal, and a control circuit inputted with the output of the second comparator for controlling degree of opening of the inlet variable stationary blade. In a modification the generator is driven by both the gas turbine and steam turbine.
