Abstract
A gas turbine includes a compressor for producing compressed air, a combustor for burning fuel with the compressed air, and a turbine driven by combustion gas generated by burning the fuel in the combustor, and is switchable between a normal operation mode which is an operation mode where a motor generator is driven by the turbine and a reverse power operation mode where the motor generator provides rotational power to the gas turbine. A fuel control device includes: a first valve for regulating pressure of fuel supplied to the combustor within a range of a first lower limit value and a first upper limit value; and a second valve for regulating pressure of the fuel supplied to the combustor within a flow rate range of a second lower limit value larger than the first lower limit value and a second upper limit value larger than the first upper limit value.
