Abstract

Provided for a device and a method for controlling a gas turbine, a gas turbine control program, and the gas turbine are: a first opening setting unit that sets a first IGV opening command value for an inlet guide vane based on factors excluding a surge limit of a compressor; a second opening setting unit that sets a second IGV opening command value for the inlet guide vane based on the surge limit of the compressor, and corrects the second IGV opening command value based on a pressure in the compressor; an opening selecting unit that selects a maximum opening as an IGV opening command value for the inlet guide vane among the first IGV opening command value and the second IGV opening command value; and an opening control unit that adjusts the opening of the inlet guide vane based on the IGV opening command value S selected by the opening selecting unit.
