Abstract
A method of correcting surge control parameters that includes providing a dynamic compressor having a compressor, driver, surge valve, and control system. The control system establishes surge control parameters such as surge detection lines, surge limit lines, and then detects the onset of a surge in the dynamic compressor. When the surge is detected the control system measures variables of the dynamic compressor such as fluid pressure, fluid speed, power, speed and valve position and based on these variables the control system automatically corrects the surge control parameters based on these variables at the time of the onset of the surge is detected. Advisory information is provided by control system to user for corrective actions to prevent surge.
