Inventor: KANN MENG JENG
IPC: F04D27/02
Filed: 1997-05-22
Abstract: PURPOSE: A method controlling surge is provided to electrically detect the occurrence of surge in the centrifugal force. CONSTITUTION: A centrifugal compressor includes an inlet valve and at least one controller for flowing fluid through the inlet valve. The method for detecting the occurrence of surge consists of the step; calculating the time rate of change of first and second compressor operating parameters; comparing the calculated time rates of change of the first and second compressor operating parameters with acceptable set points for the first and second compressor operating parameters, changing the flow of fluid through the inlet valve to avoid the surge condition if both calculated rates of change are greater than or equal to the respective set point rates of change. The discharge pressure (56) and change in current (60) drawn by the prime mover (18) are calculated and compared with reference set points to determine if the surge condition is present. The presence of a surge condition is determined by calculating and comparing discharge pressure (56) and discharge temperature (58) with reference set points.
