Abstract
A steam turbine monitoring and control system for a steam turbine having a base, a cover and interfacing plant piping system with plural feed water heaters and fluid tanks, includes a plurality of water detectors located in the interfacing plant piping system, for detecting the presence of water or cool fluid, a plurality of heater blankets covering the steam turbine, temperature detector means, coupled to the base and cover of the steam turbine, for detecting temperature differentials between the base and the cover, a water detector controller coupled to the plurality of water detectors and the temperature detector means; and monitor/alarm means, coupled to the water blanket power source, the plurality of heater blankets, the temperature detector means, and the plurality of water detectors, for indicating a condition of potential water induction when water or cool fluid is detected at any one of the plurality of water detectors, and for switching on the heater blankets to maintain absolute and relative temperatures between the cover and base within prescribed limits when the turbine is off-line.
