FIELD: gas industry. SUBSTANCE: invention relates to control of technological processes in gas industry and it can be used to protect compressors on compressor gas lines from surges. Efficiency of control over compressor station operation is improved owing to revealing situations at which surges can appear at changes of state or mode of operation of definite objects of gas dynamic system. Surge is precluded by delivering signal increasing distance settings of recirculation lines of said compressors from surge lines or supplying signal for partially opening of antisurge valves of said compressors into antisurge control subsystems of compressors in which surging is probable. EFFECT: enhanced efficiency of antisurge control. 1 dwg
