  • Control device, control method, and program
    Patent number: 11828225
    Abstract: A control device for adjusting an amount of fuel to be supplied to a gas turbine based on a rotational speed of the gas turbine, such that a frequency of electric power output by a power generator that generates electric power using the gas turbine is within a given range, includes a load value acquisition unit configured to acquire a load value that is a value of a load applied to the power generator after cutoff of a part of the load applied to the power generator when the part of the load applied to the power generator is cut off, an arithmetic unit configured to calculate an adjusted value that is a value of the load different from the load value by carrying out an arithmetic operation on the load value and a bias, and a command unit configured to adjust the amount of fuel by outputting a first signal for causing the power generator to output electric power corresponding to the adjusted value.
