본 발명은 복합 사이클 발전소(1)를 작동하기 위한 방법에 관한 것으로서, 복합 사이클 발전소(1)는 가스 터빈(2) 및 증기 터빈(3)을 포함하고, 가스 터빈(2) 및 증기 터빈(3)을 운전 정지하기 위해, 가스 터빈(2) 및 가스 터빈 증기 터빈(3)은 가스 터빈(2)과 증기 터빈(3)이 실질적으로 동일한 시점(t1)에 릴리프되는 이러한 방식으로 작동된다. A method for operating a combined cycle power plant, wherein the combined cycle power plant has a gas turbine and a steam turbine and also a shutting-down device, and wherein, for shutting down the gas turbine and the steam turbine, the gas turbine and the steam turbine are operated within a time window that extends from the beginning of the shutting-down procedure at a first time to the falling of the steam temperature to a lower limit value at a second time by the shutting device in such a way that the gas turbine and the steam turbine are relieved substantially at the same time and the block power falls to zero, thermal energy that is stored in the combined cycle power plant preventing immediate falling of a steam temperature to operation below a minimum power output of the gas turbine within the time window.
