Abstract

A device for controlling gas turbine equipment includes: a combustion load command generator configured to determine a combustion load command value, which is a parameter having a positive correlation with an inlet temperature; a flow rate ratio calculator configured to determine 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 configured to determine a valve opening degree of a fuel valve for each of the nozzles based on the flow rate ratio of the fuel supplied to each of the nozzles. The combustion load command generator has: a first load command calculation unit configured to determine the combustion load command value for a first fuel; and a second load command calculation unit configured to determine the combustion load command value for a second fuel.
