METHOD AND APPARATUS FOR COMPRESSOR CONTROL AND OPERATION IN INDUSTRIAL GAS TURBINES USING STALL PRECURSORS

An apparatus for monitoring the health of a compressor including at least one sensor operatively coupled to measure the dynamic pressure of gases flowing through the compressor, a processing system coupled to at least one sensor, the processor system recording and processing the measurements made by at least one sensor. The apparatus further includes a comparator that compares the sensor measurements with predetermined baseline values, and a real-time controller coupled to the comparator, the controller initiating corrective actions to prevent a compressor surge if the sensor measurements deviate from the predetermined baseline values.
