Title:
GAS TURBINE CONTROL DEVICE, GAS TURBINE CONTROL METHOD, AND GAS TURBINE CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/084922
Kind Code:
A1
Abstract:
This gas turbine control device controls a gas turbine comprising a combustor capable of generating combustion gas for driving the gas turbine by cofiring a first fuel and a second fuel. When it is determined that the supply of the second fuel to the combustor is being at least partly shut off, the present device calculates a shutoff-time fuel flow rate to be supplied to the combustor in accordance with a fuel cofiring ratio after the second fuel is at least partly shut off. Moreover, after the second fuel is at least partly shut off, the device outputs a fuel flow rate command value corresponding to the shutoff-time fuel flow rate, before reaching the fuel cofiring ratio.
