Abstract

The article substantiates the need to develop energy-saving regimes for hydropower facilities, including the construction of large hydroelectric power plants and irrigation pumping stations. The aim of the research is to improve the operational characteristics of hydropower installations of large hydroelectric power plants and pumping stations. The substantiation of technological, ecological factors is given. Given that large pumping stations are very energy-intensive facilities, recommendations are given for the modernization of water supply facilities, in particular, suction pipes and the flow part of pumps. Energy-saving modes are based on reducing hydraulic losses in the hydraulic unit and increasing the efficiency of the units. In order to increase the efficiency of pumps and reduce operating costs, it is necessary to ensure the introduction of hydraulic process control methods at pumping stations, primarily large ones, to establish reasonable volumes of water supply, provided by the technical condition of the equipment, taking into account the optimal level of its efficiency, and to carry out controlled operation.The article presents the results of a study of renewable energy installations and the determination of combination conditions and the choice of power for each type of power plant.
