Abstract
A method for controlling a steam power plant is provided. The method includes the steps of providing a first signal showing a reduction of the current power level of the generator, generating a second signal showing a short circuit interruption as a function of the first signal, resetting the second signal after a predetermined time period and blocking the second signal for a predetermined period of time, stopping and subsequently starting the turbine as a function of the second signal, generating a third signal showing a load rejection as a function of the first signal, and permanently stopping the turbine as a function of the third signal. A device for controlling a steam power plant is also provided.
