Abstract
In one embodiment, a plant control apparatus controls a power plant, which includes a gas turbine, a generator driven by the gas turbine, an exhaust heat recovering boiler to generate first steam using heat of exhaust gas from the gas turbine, a steam turbine driven by the first steam, and a clutch to connect a first shaft connected to the gas turbine and generator with a second shaft connected to the steam turbine. The apparatus includes a starting module to start the gas turbine and generator while holding the steam turbine in a stop state, when the clutch is in a released state. The apparatus further includes a warming module to warm the steam turbine by supplying second steam from equipment different from the boiler to the steam turbine in parallel with the starting of the gas turbine and generator, when the clutch is in a released state.
