COMPRESSOR SHOP PROCESS CONTROL METHOD Russian patent published in 2003 - IPC

FIELD: gas industry. SUBSTANCE: invention relates to control of technological processes in compressor stations of main gas lines. Proposed method includes control of operating conditions of compressor shop by stabilizing value of one of parameters P_out, Q_out, or ε,, control of speed of rotation and antisurge control of each gas transfer set, including control of distance of working point of centrifugal blower from border of recirculation and control of antisurge valve of blower, cyclic redistribution of load between separate gas transfer sets at preservation of stability of operation of compressor shop by increasing power of gas transfer set with minimum value sensitivity factor characterizing increment of summary flow rate of fuel gas of compressor shop relative to increment of power put out by compressor shop into gas line at change of power output of i-th gas transfer set and reduction of power of gas transfer set featuring maximum sensitivity factor. EFFECT: improved efficiency of operation by provision of minimum summary flow rate of fuel gas in compressor shop at preservation of stability of chosen parameter (P_out, Q_out or ε). 3 cl, 5 dwg
