PROBLEM TO BE SOLVED: To provide a combined cycle power generation plant capable of conducting operation which is excellent in followability to demand output and efficiency.SOLUTION: A combined cycle power generation plant includes: a gas turbine 1; an auxiliary burner 8 which burns a fuel to heat an exhaust gas in the gas turbine; a steam turbine 6 driven by steam generated by recovering heat of the exhaust gas in the gas turbine; and a power generation output control device 10 which controls power generation output (MW) generated by the gas turbine 1 and the steam turbine 6 on the basis of the demand output (MWD). The power generation output control device 10 controls the output of the auxiliary burner 8 on the basis of the demand output and controls the output of the gas turbine 1 on the basis of a difference between the demand output and the power generation output. |
