Abstract (en)
A method of surge protection for a dynamic compressor (12) that has a corresponding compressor map (32). A control system continually calculates an equivalent polytropic head parameter heq in order to define a surge limit line (38). The system then calculates a control parameter and determines the distance of the control parameter from the surge limit line wherein the control parameter is dynamic to changes in compressor load and invariant to changes in suction conditions and gas compressibility. As a result of the distance of the control parameter to the surge limit line, a surge valve (20) of the dynamic compressor is actuated to prevent surge.
