Claim 0:
1. An output corrector for a gas turbine including a compressor that compresses air to generate compressed air, a combustor that combusts fuel in the compressed air to generate combustion gas, and a turbine to be driven by the combustion gas, the output corrector comprising:
a correction coefficient creation unit that creates a correction coefficient to be used when a control output of the gas turbine is corrected;
an output correction unit that corrects the control output using the correction coefficient, and that outputs a corrected control output as a correction control output;
an output reception unit that receives at least an output from an output meter that detects an output of the gas turbine; and
an output storage unit that stores the output received by the output reception unit,
wherein the correction coefficient creation unit includes a first coefficient element calculation unit that calculates a first coefficient element, a second coefficient element calculation unit that calculates a second coefficient element, and a correction coefficient calculation unit that calculates the correction coefficient using the first coefficient element and the second coefficient element,
the output storage unit stores a reference output that is an output under a condition where the gas turbine outputs a maximum output at a reference time in the past, and an immediately preceding output that the output reception unit receives under a condition where the gas turbine outputs a maximum output in an immediately preceding time period closer to a current time than to the reference time,
the first coefficient element is a ratio of the immediately preceding output stored in the output storage unit to the reference output stored in the output storage unit, and
the second coefficient element is a ratio of a current output that the output reception unit receives under a condition where the gas turbine outputs a maximum output in a current time period between the immediately preceding time period and the current time, to the immediately preceding output stored in the output storage unit.
