Title: CONTROL DEVICE FOR GAS TURBINE AND CONTROL METHOD FOR GAS TURBINE
Abstract:
In the present invention, a combustion gas temperature estimation value is calculated with high calculation accuracy and high responsiveness is achieved. The control device has: a detection value acquisition unit (52) for acquiring a detection value (I1) of at least one of a fuel supply amount, a compressed air pressure, and electric power generated by a generator; an exhaust gas temperature acquisition unit (54) for acquiring an exhaust gas temperature detection value (O1); a combustion gas temperature estimation value calculation section (60) for calculating a combustion gas temperature estimation value (I2) on the basis of the detection value (I1); a correction term acquisition section (64) for calculating a correction term (X4) on the basis of a ratio between the combustion gas temperature estimation value (I2) and the exhaust gas temperature detection value (O1); a corrected combustion gas temperature estimation value calculation section (66) for calculating a corrected combustion gas temperature estimation value (I3) by correcting the combustion gas temperature estimation value (I2) with the correction term (X4); and a gas turbine control unit (58) for controlling the gas turbine on the basis of the corrected combustion gas temperature estimation value (I3).
