About the works of modeling and designing a pump-turbine system in pumped-storage power plants (review)

The paper presents an overview of research in the world on the design and creation of pumped hydroelectric energy storage with hydraulic machines having optimal characteristics according to the principle of operation of reversible pump turbines, optimization of their flow part. Special attention was paid to the work on the study of the operation of the hydraulic machine in pumping and turbine modes. As the study of publications has shown, active research is being conducted abroad on the design and creation of hydroelectric power plants with hydraulic machines having optimal characteristics. When designing hydraulic machines, various mathematical modeling systems are used. As international experience shows, the study of hydraulic machines and, in particular, the pump-turbine, using computational fluid dynamics tools, for example, CFD modeling is becoming increasingly widespread.
