Anti-surge valve control method of Multi gas Compressor Systems

摘要

The present invention relates to a method for controlling an anti-surge valve of a parallel gas compressor system, and more specifically, an anti-surge of a parallel gas compressor system capable of efficiently controlling an anti-surge valve to prevent a surge phenomenon of the parallel gas compressor. It relates to a valve control method. To this end, a method for controlling an anti-surge valve of a parallel gas compressor system composed of a plurality of gas compressors, the method comprising: a load signal receiving step of receiving information on a volume flow rate of a gas required by a customer; A signal 1 signal generation step of generating a signal for controlling the anti-surge valve using the volume flow rate information of the gas received in the load signal reception step; A volume flow rate sensing step of sensing the volume flow rate of the gas sent to the compressor; A signal 2 signal generation step of generating a signal for controlling the anti-surge valve using the information detected in the volume flow detection step; A final signal generation step of generating a final signal based on the signal 1 signal and the signal 2 signal generated in the signal 1 signal generation step and the signal 2 signal generation step; It provides an anti-surge valve control method of a parallel gas compressor system comprising a; anti-surge valve control step of finally controlling the anti-surge valve through the final signal generated in the final signal generation step.
