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.

Steam turbine control

A turbine control unit and method for controlling a turbine, in particular for controlling the start-up of a turbine, the unit being designed as a cascade controller having a master controller and an inner controller, the master controller being a thermal stress controller for the components subjected to thermal stress.

A quick acting control valve for a steam turbine is provided. The quick acting control valve includes a valve box and a control valve cone which is arranged in the valve box so as to be displaceable along its center axis, whereby the control valve cone may be brought into an open position in which the control valve cone, with its control valve cone surface is lifted off the valve box and into a closed position in which the control valve cone rests against the valve box with its control valve cone surface, and a quick acting valve piston which is arranged in the valve box so as to face the back of the control valve cone facing away from the control valve cone surface, the quick acting control valve piston, on its outer peripheral edge, always resting on the valve box in a steam-tight manner.
