  • Method and device for controlling a steam power plant
    Patent number: 8624414
    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.
    Type: Grant

  • Clutch engagement process in which the target angle is controlled
    Patent number: 8137240
    Abstract: A method for engaging a drive shaft of a turbo engine with an output shaft by means of a clutch is provided. The turbo engine is run up to a rotational speed that is subsynchronous to the speed of the output shaft and is maintained at the steady speed before a signal is set or before starting the engagement process.

  • Method for regulating a steam turbine, and corresponding steam turbine
    Publication number: 20040101396
    Abstract: The invention relates to a method for regulating a steam turbine (1), according to which steam is fed to the steam turbine (1) via at least three valves, whereby one of the valves is regulated as a regulating valve (9, 11), and at least two valves are controlled as control valves (13, 15).
