The problem of optimizing pumping units for oil transportation

Abstract

During pipeline transportation of oil through main oil pipelines, the greater part of the energy consumed is spent on the operation of main and booster pumping units at oil pumping stations. In this regard, the determination of the optimal operating modes of pumping units is an urgent problem for energy saving. The article is devoted to the optimization of the operation of pumping units for energy saving of oil pipeline transport. The operation of pumping units is regulated using removable rotors with different diameters of impellers or a frequency-controlled drive. An optimization criterion has been formulated to minimize the operating costs of pumping units. A technique for determining the energy consumption of pumping units with different diameters of impellers and a frequency-controlled drive is presented. An algorithm for finding the optimal operating mode of pumping units is presented, which was built using the definitions of graph theory and dynamic programming.
