Abstract (en)
Controlling surging in a compressor by monitoring the high frequency (40 - 500 Hz) fluctuations in a parameter such as the delivery pressure. As surging conditions are approached the amplitude of these fluctuations, generally at a frequency characteristic of the system, progressively increase. When the amplitude reaches a predetermined value, for example about twice the amplitude of the fluctuations at the design maximum compressor throughput, a bypass or vent valve is opened to increase the throughput through the compressor.
