Abstract: A method for operating a steam turbine where steam turbine has at least two sub-turbines, wherein the steam turbine is paired with a steam turbine controller which has a sub-turbine controller for each of the sub-turbines, and each sub-turbine controller compares respective target values with respective actual values of the respective sub-turbine during operation in order to determine a respective control deviation for each sub-turbine.

Abstract: 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.

Abstract: A method for coupling a rotating device, in particular a steam turbine, and a shaft device, in particular a gas turbine, having the following steps: detecting a differential angle between the shaft device and the rotating device; detecting a differential speed between the shaft device and the rotating device; predicting a coupling angle at which the rotating device and the shaft device would be coupled if the rotating device were accelerated with a known acceleration up to the start of the coupling-in; comparing the predicted coupling angle with a target coupling angle, and calculating therefrom a setpoint acceleration such that the predicted coupling angle matches the target coupling angle.
