Abstract
A gas turbine includes a purge gas supply system for supplying a purge gas to a fuel oil injection nozzle for injecting a fuel oil to a combustion chamber. A gas turbine control device is configured to set a supply pressure target value of the purge gas, based on an operating state of the gas turbine, and control a purge gas supply pressure adjustment device so that a supply pressure of the purge gas becomes the supply pressure target value. The gas turbine control device is further configured to limit an increase rate of the supply pressure target value to be less than or equal to an increase rate upper limit, and correct the increase rate upper limit so that the increase rate upper limit is raised if correction of the increase rate upper limit is determined to be necessary based on the operating state of the gas turbine.
