摘要： A method of controlling a steam turbine, having a controller controlling at least the position of a steam inlet valve located in a steam conduit between a steam generator and the turbine to control mass flow into the turbine, includes selecting, before beginning startup, a predefined set of startup sequences of setpoints based on a turbine status at the beginning of startup and/or a startup mode chosen by the operator, the set of startup sequences of setpoints includes parameters controlled and not controlled by the controller; using the controller to control the parameters controlled by the controller so as to progress the turbine from setpoint to setpoint in accordance with predefined set of startup sequences until reaching a release point; and at the release point, delaying moving to the next setpoint until actual setpoint values agree with predefined release point setpoint values for parameters not controlled by the controller.

摘要： A steam turbine is provided having a relief groove which is arranged in the region of the equalizing piston and extends in the circumferential direction of the rotor. The relief groove, with regard to an inlet passage, is arranged in the axial upstream direction so that it is arranged on the rotor outside a region in which the steam flow enters the bladed flow path via the inlet passage. The relief groove, with regard to the first blade row, is arranged in a region in which the greatest thermal stresses can arise in the rotor. As an option, the relief groove has a cover for reducing vortex flows, and also devices for reducing heating of the groove or devices for active cooling. The steam turbine allows an increased number of risk-free running up and running down operations of the steam turbine with minimum detriment to the turbine performance.
