Mathematical model of electricity consumption at oil pumping stations

One of the key tasks for improving the energy efficiency of oil pumping stations (OPS) in main oil pipelines is conducting a scientific and technical analysis of the electricity consumption structure across primary and auxiliary complexes and equipment systems. Based on the results of this analysis, a theoretical model of the electricity consumption structure should be developed, which is necessary for forecasting costs at existing and reconstructed OPS, taking into account changes in pumping technological regimes. There are several challenges in creating such models based on industry regulations, as they cannot fully account for significant changes occurring in the industry due to the evolving geopolitical situation and related processes affecting the energy consumption structure of pipeline transport facilities. The article presents the results of an analysis of electricity consumption using the example of a typical OPS of JSC "Transneft-Volga Region" for two characteristic periods: full and partial station load. Based on the analysis, data were obtained for a mathematical model linking electricity consumption with the main technological parameters of oil pumping. Verification of the theoretical assumptions was carried out by comparing the simulation results with actual electricity consumption data at the station. The comparison showed good agreement between the calculated and instrumentally recorded parameters.
