Analysis of the main layout and arrangement of basic hydropower equipment of the Zagorskaya hydroaccumulating electric power (HAEP) plant

Design options are analysed to select a principal electric circuit and to define the arrangement of main electrical and hydromechanical equipment of the Zagorskaya HAEP plant. This analysis was made to provide reliability and optimization of energy parameters of this plant. Several problems associated with the arrangement and composition of equipment at the HAEP plant are considered. Several recommendations are made. In particular, it is discussed to what degree it is expedient to install a near-turbine gate from the side of the upper pool at HAEP plants to be constructed.
