Kind Code:
A1
Abstract:
A device for controlling gas turbine equipment comprises: a combustion load command generator that determines a combustion load command value, which is a parameter having a positive correlation with an inlet temperature, which is the temperature of combustion gas at an inlet of a turbine; a flow rate ratio calculator that determines a flow rate ratio of fuel supplied to each of a plurality of types of nozzles of a combustor in accordance with the combustion load command value; and a valve opening degree calculator that determines the valve opening degree of a fuel valve for each of the plurality of types of nozzles on the basis of the flow rate ratio of the fuel supplied to each of the plurality of types of nozzles. The combustion load command generator has: a first load command calculation unit that determines the combustion load command value for a first fuel, which is a fuel type indicated by a fuel type command; and a second load command calculation unit that determines the combustion load command value for a second fuel, which is a fuel type indicated by a fuel type command.
