Abstract
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.
