The principles of pumping station control, providing the most efficient modes of operation are discussed in the article. To perform calculations of energy-efficient operation modes, a mathematical description of the system has been proposed. It is shown that the increase of energy efficiency in the system is achieved by choosing a power circuit, splitting up sections of the pumping station, selecting the appropriate operation algorithms for each of the sections. An electrical equivalent circuit of the control object is proposed. Comparison of the energy consumption of the pumping station was carried out for the following cases: in the first, the cascade did not work, and in the second, the flow was controlled in a cascade over the entire range of flow variation. It is established that the proposed control algorithms can significantly reduce energy consumption from the mains supply by about 30%.
