design of pumped water storage scheme for abandoned reservoirs

Solved In a pumped-storage scheme, water is supplied to a

In a pumped - storage scheme, water is supplied to a single turbine through a 2 0 0 m long, 2 m diameter penstock line. The power plant uses two centrifugal pumps to pump water back to the upper reservoir ( headrace or the dam), using the same penstock pipeline. Basic data are as follows: Pumps two in number, rated capacity 6 M W ...

A New Approach to Pumped Storage Hydropower

Pumped-storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power (discharge) as water moves down through a turbine; this draws power as it pumps water (recharge) to the upper reservoir. PSH capabilities can be characterized …
