Method and apparatus for load sharing to control a main process gas parameter of a compressor station with multiple dynamic compressors.

摘要

METHOD AND APPARATUS FOR MAINTAINING A main parameter DISCHARGE GAS WORK AS A discharge pressure suction pressure, discharge flow, ETC. A compressor station with multiple compressors DINAMICOS that allows a station controller CONTROL THE MAIN PARAMETERS DISCHARGE GAS WORK TO INCREASE OR DECREASE THE TOTAL PERFORMANCE OF THE STATION TO RESTORE THE MAIN PARAMETERS DISCHARGE GAS AT A LEVEL REQUIRED TO BASE OF CHANGE FIRST, simultaneously, the behavior of all individual compressors, REDUCING, FOR EXAMPLE, YOUR SPEEDS And then opening simultaneously rELIEF VALVES overpressure INDIVIDUAL after POINTS WORKING ALL MACHINES HAVE REACHED ITS CONTROL LINES RESPECTIVE overpressure. ACCORDING TO PLAN PROPOSED cargo compartment, a compressor is automatically selected as the main machine. FUNCIONAMIENTOEN FOR PARALLEL COMPRESSOR selected as the main IS THAT MORE IS YOUR LINE OUT OF CONTROL overpressure. TO OPERATE IN SERIES, main compressor has the value "R" LOWER STANDARD OF REPRESENTING BOTH THE DISTANCE CONTROL YOUR LINE overpressure AS EQUIVALENT mass flow rate through the compressor. THE MAIN COMPRESSOR followed THE REST OF THE EVENING COMPRESORES DISTANCES TO ITS CONTROL LINES overpressure RESPECTIVE criterias "R" REGARDING THE MAIN COMPRESSOR.
