Provided is a control device of a gas turbine including a compressor, a combustor, and a turbine. The control device executes load control of allowing an operation control point for operation control of a gas turbine to vary in response to a load of the gas turbine. The operation of the gas turbine is controlled on the basis of a rated temperature adjustment line for temperature adjustment control of a flue gas temperature at a predetermined load to a rated flue gas temperature at which performance of the gas turbine becomes rated performance, a preceding setting line for setting of the flue gas temperature at the predetermined load to a preceding flue gas temperature that becomes lower in precedence to the rated flue gas temperature, and a limit temperature adjustment line for temperature adjustment control.

Control device, system, control method, power control device, gas turbine, and power control method

A control device is configured to control a gas turbine that is configured to compress a suctioned air with a compressor to obtain compressed air, mix a fuel supplied from a combustor with the compressed air to burn the fuel and the compressed air to generate a combustion gas, operate a turbine with the combustion gas to rotate a rotor, and discharge the combustion gas that has operated the turbine as a flue gas. The compressor includes an inlet guide vane which is capable of adjusting a degree of opening and is on an air-suction side, and the control device is configured to execute temperature adjustment control to control the degree of opening of the inlet guide vane along a temperature adjustment line indicating an upper limit temperature of a flue gas temperature defined according to a load of the gas turbine.
