Forecasting rational working modes of long-operated gas-transport systems under conditions of their incomplete loading

Prolonged operation of the gas-transport system in conditions partial loading involves frequent changes volume gas transportation, which necessitates prompt forecasting operation. When modes transport system, main criterion optimality implies maximum pumping. After all, this case, largest profit company is achieved under condition full provision consumers with energy. In incomplete caused by a shortage supply, criteria change significantly. First, equipment operated ranges far from nominal ones leads to growth energy consumption. Secondly, performance cause high-amplitude pressure fluctuations at outlet compressor stations. Based on mathematical modeling nonstationary processes, amplitude and frequency stations can pipeline overload have been established. To prevent this, it was proposed reduce initial relative one. Calculated dependence obtained connects characteristics process. Reduction consumption for transportation due shutdown individual (CS). Mathematical has made possible establish regularities reduction productivity duration process depending location station route. With an increase number compression stations, degree decrease nonstationarity reduces The established patterns solutions will improve reliability preventing cost selecting running numbers known productivity.
