摘要： A blade vibration monitor backpressure limiting system (BVMBLS), that in addition to direct blade vibration and condenser backpressure monitoring utilizes other plural types of other parallel, real time monitored power plant operation state (OS) information that influences blade vibration. The system references previously stored information in an information storage device that associates respective types of monitored OS information with blade vibration. The BVMBLS determines in real time a likelihood of whether any of the monitored operation states, alone or in combination with other types of monitored operation states, is indicative of a turbine blade vibration safe operation (SO). The BVMBLS determination is utilized to increase or reduce power generation load incrementally so that power efficiency and maximum load is enhanced while turbine blade vibration is maintained in a safe operation state. The previously stored information is updated to new association information.

摘要： A system for providing a demand signal to control the boiler inputs in a boiler-turbine combination operating in a sliding pressure mode with the throttle valve being controlled to maintain the desired generator output. The demand signal for the boiler inputs is obtained by multiplying the ratio of first stage turbine pressure to throttle pressure by the throttle pressure set point and the throttle pressure set point is controlled so as to maintain the ratio at a preset value. The demand signal is modified to trim the boiler inputs to maintain the throttle pressure at its set point.
