Patent number: 11391184Abstract: In one embodiment, a plant control apparatus includes a first stop controller configured to, when stopping a plant, stop a steam turbine to start to drop rotating speed of a second shaft of the steam turbine from rated speed, and start to drop rotating speed of a first shaft of a gas turbine from the rated speed while continuing combustion of a combustor after the stop of the steam turbine. The apparatus further includes a second stop controller configured to shut off fuel of the combustor to stop the gas turbine when the rotating speed of the first shaft drops to first speed. The second stop controller stops the gas turbine such that the rotating speed of the first shaft catches up with the rotating speed of the second shaft at second speed that is equal to or lower than the first speed and a clutch is engaged.Type: GrantFiled: August 25, 2020Date of Patent: July 19, 2022Assignees: TOSHIBA ENERGY SYSTEMS & SOLUTIONS CORPORATION, TOSHIBA PLANT SYSTEMS & SERVICES CORPORATIONInventors: Mohammed Ameen Abbas Alzuraiqi, Masayuki Tobo, Yuta Iwata, Mizu Kajihara, Shinobu Chiba
