This article addresses the issue of improving the energy efficiency of gas transportation equipment in main gas pipelines. To ensure the operation of gas compressor units (GCUs), transported gas is used, and as a result, compressor stations (CSs) consume a significant amount of fuel gas for their own needs. Therefore, increasing the length of main gas pipelines requires a high degree of fuel gas utilization efficiency. The article demonstrates the principles of using GCUs for gas transportation and the operating modes of GCUs. An analysis of methods for assessing the efficiency of GCU operation is conducted. To obtain a forecast of GCU operating modes, a mathematical model for evaluating the efficiency of GCU operating modes is proposed based on real statistical data of equipment operating mode parameters during industrial operation of GCUs in main gas pipelines. The regression model for GCU operating efficiency obtained from calculating the dependency of fuel gas consumption on pressure drop and transported gas flow inadequately reflected the GCU operating mode. To improve accuracy, a regression model for assessing the efficiency of GCU operating modes is developed based on quadratic dependencies on pressure drop, transported gas flow, and gas temperature at the inlet, satisfying the dispatcher control of GCU efficiency.
