Abstract:

Purpose. To improve the technology of prompt detection of a deviated gas compression process in a gas compressor station of underground gas storage from a normal gas process within the context of improving the efficiency of its practical application to prevent accidents caused by the phenomenon of surging in system – “centrifugal supercharger of compressor units – pipeline”.

Methodology. Basic methods of this study are general scientific and special methods, techniques and approaches of knowledge of processes and phenomena, namely systematic approach to the analysis of a gas compression process and phenomena of surging in centrifugal superchargers of gas compressor units in underground gas storage compressor stations, the position of modern control theory, informative and production technologies.

Findings. The informative technology of early detection of a deviated gas compression process from a normal gas compression process, in particular, surging phenomenon based on the analysis of phase portraits of controlled parameters is proposed.

Originality. Based on multidimensional measuring, methodological approach how to identify a deviated gas compression process from a normal gas process associated with the phenomenon of surging, accompanied by uncertainty, imbalance, the presence of phase transitions is first done. It allows detecting the phenomenon of surging in the system “centrifugal supercharger of compressor units – pipeline” in time.

Practical value. The proposed informative technology of early detection of a deviated gas compression process from a normal gas process can be used to activate alarms, which gives the operator a certain time to make a decision on how to act further.
