Load Sharing Method And Apparatus For Controlling A Main Gas Parameter Of A Compressor Station With Multiple Dynamic Compressors

US Patent:
5347467, Sep 13, 1994
Filed:
Jun 22, 1992
Appl. No.:
7/902006
Inventors:
Naum Staroselsky - West Des Moines IA
Saul Mirsky - West Des Moines IA
Paul A. Reinke - Elkhart IN
Paul M. Negley - Urbandale IA
Robert J. Sibthorp - Ankeny IA
Assignee:
Compressor Controls Corporation - Des Moines IA
International Classification:
F04D 2702
G04B 1302
US Classification:
364510
Abstract:
A method and apparatus for maintaining a main process gas parameter such as suction pressure discharge pressure, discharge flow, etc. of a compressor station with multiple dynamic compressors, which enables a station controller controlling the main process gas parameter to increase or decrease the total station performance to restore the main process gas parameter to a required level, first by simultaneous change of performances of all individual compressors, for example, by decreasing their speeds, and then after operating points of all machines reach their respective surge control lines, by simultaneous opening of individual antisurge valves. In the proposed load-sharing scheme, one compressor is automatically selected as a leading machine. For parallel operation, the compressor which is selected as the leader is the one having the largest distance to its surge control line. For series operation, the leader has the lowest criterion "R" value representing both the distance to its surge control line and the equivalent mass flow rate through the compressor.
