Abstract
(EN)
In a method for operating a multi-shaft combined cycle plant, a low load mode for adjusting the output of the multi-shaft combined cycle plant by adjusting only the output of a gas turbine, and a high load mode in which the output of the multi-shaft combined cycle plant can be adjusted by adjusting the output of both the gas turbine and a steam turbine, are switched according to the required load (S15). In the low load mode, the steam turbine is supplied with steam at a standby flow rate amount at which the steam turbine can maintain a predetermined initial load, and the initial load is imposed on the steam turbine (S21 to 23).
(FR)
L'invention concerne un procédé pour faire fonctionner une installation à cycle combiné à plusieurs arbres, qui, selon la charge requise (S15), fait commuter l'installation entre un mode faible charge pour régler la sortie de l'installation à cycle combiné à plusieurs arbres en réglant uniquement la sortie d'une turbine à gaz, et un mode charge élevée dans lequel la sortie de l'installation à cycle combiné à plusieurs arbres peut être réglée en réglant l'une et l'autre sorties de la turbine à gaz et d'une turbine à vapeur. Dans le mode faible charge, la turbine à vapeur est alimentée en vapeur à un débit d'attente pour lequel la turbine à vapeur peut conserver une charge initiale prédéterminée, et la charge initiale est imposée à la turbine à vapeur (S21 à 23).

多軸コンバインドサイクルプラントの運転方法では、ガスタービンの出力調節のみで多軸コンバインドサイクルプラントの出力を調節する低負荷モードと、ガスタービンの出力調節及び蒸気タービンの出力調節で多軸コンバインドサイクルプラントの出力を調節できる高負荷モードとを、要求負荷に応じて切り替る(S15)。低負荷モードでは、蒸気タービンが予め定められている初負荷を維持できる待機流量の蒸気を蒸気タービンに供給し、蒸気タービンに初負荷をかける(S21~23)。
