摘要： 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.

摘要： A method for starting a gas and steam turbine system which includes a gas turbine system which includes at least one gas turbine, in addition to at least one steam turbine system which includes at least one steam turbine and at least one steam system is provided. Heat produced by the working fluid and which is released in the gas turbine is guided to the steam system in order to produce steam which drives the steam turbine. During starting, the gas turbine is started prior to the steam turbine and the steam turbine is started in the presence of the first steam in the system and is impinged upon by said steam.

摘要： A method for starting a steam turbine system having a steam generator, a steam turbine which is connected to the steam generator and includes at least two turbine stages that, at the time of starting the steam turbine system, have different outlet temperatures, a condenser connected to the steam turbine and a consumer driven by the steam turbine, in which the steam generated in the steam generator is used to start the steam turbine, wherein, until the steam generated in the steam generator reaches a predetermined temperature that at least corresponds to the temperature requirement of the turbine stage with the higher outlet temperature, only the turbine stage with the lower outlet temperature is operated, and in that the turbine stage with the higher outlet temperature is brought on-line only once the predetermined temperature has been reached.
