A gas turbine control device is for controlling a gas turbine which includes a combustor capable of co-firing a first fuel and a second fuel with a lower heating value per unit volume than the first fuel. The gas turbine control device includes a processor for determining a supply state of the second fuel to the combustor, controlling a pilot fuel ratio which is a ratio of fuel distributed to a pilot fuel injection nozzle among a plurality of fuel injection nozzles of the combustor, and controlling the pilot fuel ratio to temporarily increase when the supply state is determined to be a shut-off state.
A gas turbine control device for controlling a gas turbine which includes a combustor capable of co-firing a first fuel supplied through a first fuel supply line and a second fuel with a lower heating value per unit volume than the first fuel and supplied through a second fuel supply line joined with the first fuel supply line at a confluence point on a downstream side of the first fuel supply line and the second fuel supply line, the gas turbine control device comprising:
