    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 method is provided for operating a combined cycle power plant. Flue gas of a gas turbine is used for producing steam for a steam turbine. A reliable and flexible black start network restoration is achieved by: a) in island mode, supplying internal consumers by the gas turbine, the operating point of which is selected so that a minimum steam temperature is achieved; b) in island mode, the steam turbine is synchronized and ramped up to an operating point where a maximum power increase is achieved, the resulting steam turbine load change is compensated by the gas turbine; c) consumer loads are connected blockwise; d) the increase in the demanded load being provided by the steam turbine; e) the load of the steam turbine is gradually reduced increasing its load-increasing capacity; and steps c)-e) are repeated until the power plant's base load is achieved.
