Method and apparatus for continuous prediction, monitoring and control of compressor health via detection of precursors to rotating stall and surge

摘要

An apparatus for monitoring the health of a compressor (14) having at least one sensor (30) operatively coupled to the compressor for monitoring at least one compressor parameter, a processor system (36) embodying a stall precursor detection algorithm, the processor system operatively coupled to the at least one sensor, the processor system computing stall precursors. A comparator (40) is provided to compare the stall precursors with predetermined baseline data, and a controller (42) operatively coupled to the comparator initiates corrective actions to prevent a compressor surge and stall if the stall precursors deviate from the baseline data, the baseline data representing predetermined level of compressor operability.
