Abstract
System and methods for detecting surge conditions in a compressor system are presented. In some embodiments, a method for detecting surge conditions may include receiving a plurality of flow measurements relating to a flow rate through the compressor system. Amplitude calculations may be performed based on at least one of the plurality of flow measurements to identify a possible surge condition. Frequency calculations may also be performed to identify a possible surge condition. A surge condition may be detected based on the results of the amplitude calculation and the frequency calculation and, in response, a surge detection control signal may be generated.
