Abstract
A gas turbine control device including: a fuel flow rate calculation unit that calculates a fuel flow rate indicating an amount of fuel entering a combustor; an air flow rate calculation unit that calculates an air flow rate; a turbine inlet temperature calculation unit that calculates a turbine inlet temperature, on the basis of the fuel flow rate, the air flow rate, and a physical model formula for thermal energy balance about the combustor; a heat balance computation unit that performs computation to satisfy the heat balance of the gas turbine; a state detection unit that detects the state of the gas turbine; and a correction processing unit that, on the basis of the computation result output by the heat balance computation unit, corrects one or both of the fuel flow rate and the air flow rate, and gives the corrected flow rate to the turbine inlet temperature calculation unit.
