Intake of the Zagorsk and Kaisiadorys pumped-storage stations
Conclusions 1. For the Zagorsk PSS a new design of the intake-offtake with an extended portal was developed, which is characterized by stable hydraulics of the flow, high energy characteristics in the turbine regime, and improved characteristics in the pump regime. Further improvement of the shape of the offtake (in a pump regime) is possible by greater compression of the outlet diverging duct (to 8–12°) and elliptical shaping of the upper boundary of the portal. 2. The elimination of the trash rack of the intake in the upper reservoir, the water area of which is confined and has special preparation of the bed and facing of the upper part of the slopes, is a progressive decision making it possible to reduce head losses and to increase the efficiency of operating the equipment of the PSS.
