Abstract
A gas turbine includes a purge gas supply system for supplying purge gas to a fuel oil injection nozzle for injecting fuel oil to a combustion chamber. A gas turbine control device sets a supply pressure target value of purge gas, based on the operating state acquired from the gas turbine, and controls a purge gas supply pressure adjustment part so that supply pressure of purge gas becomes the supply pressure target value. The increase rate of the supply pressure target value is limited to be less than or equal to an increase rate upper limit. The increase rate upper limit is corrected so that the increase rate upper limit is increased when it is determined that the correction is necessary based on the operating state.
