A method for protection of compressor against surge relates to transportation of gas, in particular to system for control and adjustment of operation of superchargers of centrifugal type on gas pumping units of gas-turbine type. It can be used on compressor stations of underground gas holder as well. The method includes measurement of speed power turbine of gas turbine drive and supercharger, horizontal vibratory displacement of rear support of the supercharger, vertical vibratory displacement of rear support of the supercharger, horizontal vibratory displacement of front support of the supercharger, determination of coordinate of working point of compressor by it, its deviation from set value and change in proportion to it of state of compressor control elements. |
