ABSTRACT:
Values such as a pressure for supplying fuel gas to a gas turbine, a pressure in a combustor casing of the gas turbine, an output of a generator connected to the gas turbine, and a controlled output for a flow rate control valve are detected by sensors. The detected values are input into a control device. A differential pressure across the flow rate control valve and a target value of the differential pressure are also input into the control device. The control device performs a desired arithmetic operation based on these input values to output a lift instruction for a pressure control valve.
