1. A gas turbine control device configured to control a gas turbine including
a combustor configured to combust fuel by mixing the fuel with compressed air;
a heater configured to heat the fuel to a set temperature;
a compressor configured to generate the compressed air; and
an inlet guide vane configured to adjust an amount of intake air of the compressor,
the gas turbine control device comprising:
a fuel temperature detection unit configured to detect a temperature of the fuel at an outlet section of the heater; and
an inlet guide vane control unit configured to control an opening degree of the inlet guide vane based on an output of the gas turbine,
wherein when a deviation between the temperature of the fuel detected by the fuel temperature detection unit and the set temperature exceeds a threshold value, the inlet guide vane control unit controls the opening degree of the inlet guide vane to become larger than the opening degree when the deviation is equal to or smaller than the threshold value.
