System for detecting and correcting unwanted steam turbine operating modes has control unit processor that implements software commands to monitor sensors to detect whether operating parameters lie in range with unacceptable risk

摘要

The system has several sensors (130,160,165) that communicate with a control unit (125), at least one sensor being associated with at least one operating parameter of the high pressure turbine housing pressure and at least one with an intermediate pressure turbine housing pressure. The control unit has a processor that implements software commands to monitor the sensors to detect whether the operating parameters lie in a range with an unacceptable risk. An independent claim is also included for a method of detecting and correcting unwanted turbine operating modes.
