GAS TURBINE CONTROL DEVICE, GAS TURBINE CONTROL METHOD, AND GAS TURBINE CONTROL PROGRAM
In order to control a gas turbine in a rated operation state on the basis of a maximum output command, this gas turbine control device calculates, for an inlet guide vane for adjusting the intake air flow rate of the gas turbine and on the basis of at least one of the atmospheric pressure and the intake air temperature of the gas turbine, the basic target opening degree corresponding to the maximum output command. The opening degree of the inlet guide vane of the gas turbine is controlled on the basis of a target opening degree obtained by using a bias correction value to correct the basic target opening degree. Calculation of the bias correction value is performed such that the target opening degree becomes smaller than the basic target opening degree if the combustion temperature of the gas turbine is lower than the temperature upper limit value corresponding to the maximum output command. If the output of the gas turbine is lower than the rated output value corresponding to the maximum output command, calculation of the bias correction value is performed such that the target opening degree becomes greater than the basic target opening degree.
