GAS TURBINE CONTROL DEVICE, GAS TURBINE CONTROL METHOD, AND GAS TURBINE CONTROL PROGRAM

WIPO Patent Application WO/2023/204096

A1

A gas turbine control device of the present disclosure controls a gas turbine in which a combustor is configured in a state where a plurality of fuel supply nozzles for supplying fuel are separated into a first group and a second group. This device, on the basis of the operating state of the gas turbine, calculates a control parameter base index relating to the ratio of the amount of fuel supplied by the second group to the amount of fuel supplied by the first group. The base index is corrected using a correction value calculated on the basis of the operating state of the gas turbine. The amounts of fuel supplied by the first group and the second group are each controlled on the basis of a control parameter obtained by correcting the base index using the correction value. This correction value is calculated so that the absolute value thereof decreases to zero after the gas turbine has been started up and a prescribed length of time has passed since load addition to the gas turbine.
