Zusammenfassung:	This invention provides a gas turbine power generation equipment adapted to prevent step out of an electric power generator due to a system trouble such as a momentary power failure in a local grid including intermittent renewable energy generation equipment and the gas turbine power generation equipment. The gas turbine power generation equipment 10 that supplies electric power in cooperation with the intermittent renewable energy generation equipment 30 in the local grid 50 interconnected to a power grid 7 includes: a fuel flow control valve 201 that controls a flow rate of fuel supplied to a combustor 2; a bleed valve 105 or inlet air flow control valve 100 that controls a flow rate of air compressed by a compressor 1 and supplied to the combustor 2; and a control unit 400 configured so that if voltage on the power grid decreases below a threshold V(t), the control unit outputs a control signal to at least one of the fuel flow control valve 201, the bleed valve 105, and the inlet air flow control valve 100. The control unit 400 thereby reduces instantaneously at least one of the fuel flow rate and the compressed air flow rate. After an elapse of a predetermined time, the control unit 400 instantaneously returns the reduced flow rate to its original level.
