Abstract
A gas turbine fuel flow rate setting device includes a flow rate ratio computing unit and a flow rate computing unit. The flow rate ratio computing unit is configured to accept a parameter having a correlation with a gas turbine output, and use a predetermined flow rate ratio relationship between the parameter and a fuel flow rate ratio between a plurality of premixing nozzle groups to determine a fuel flow rate ratio corresponding to the parameter which has been accepted. The flow rate computing unit is configured to use the fuel flow rate ratio determined by the flow rate ratio computing unit to determine a flow rate of a fuel to be supplied to each of the plurality of premixing nozzle groups.
