PROBLEM TO BE SOLVED: To confirm an operation of a pressure regulation valve with a simple constitution in controlling under a constant load.SOLUTION: A gas turbine includes a combustor producing a combustion gas by burning a fuel, a pressure regulation valve for regulating a pressure of the fuel supplied to the combustor, a flow rate regulation valve for regulating a flow rate of the fuel supplied to the combustor, and a turbine driven by the combustion gas produced by the combustor. A control device 50 of the gas turbine includes a subtracting portion 70 for calculating the difference between a flow regulation valve pressure measurement value and a flow regulation valve pressure set value, a pressure regulation valve control portion 72 for controlling an opening of the pressure regulation valve on the basis of the difference calculated by the subtracting portion 70, and a bias generating portion 74 generating a bias value to be added to a set value of the pressure input to the subtracting portion 70, in confirming an operation of the pressure regulation valve. |
