METHOD FOR CONTROLLING A STEAM TURBINE WITH STEAM TAKING, CONTROL DEVICE FOR A STEAM TURBINE WITH STEAM TAKING AND STEAM TURBINE WITH STEAM TAKING

摘要

A method for controlling a steam turbine with a steam bleed for various operational tasks is provided. The operational tasks are each characterized by the type of the controlled variables used for controlling the steam turbine. A control structure is used for deriving actuating signals for actuating elements for valves. The actuating signals are derived from control signals of the regulators which are used. Only a single control structure is used for all the operational tasks. As a result, the configuration of the control is simplified, the control signals are decoupled, and a smooth changeover between the operational tasks is achieved. A device for controlling a steam turbine is also provided.
