Pumped hydro is one of more economic and reliable storage mechanisms for plants with higher capacities. To make the pumped storage system more effective, the best machine suited for this purpose must be used. Present paper deals with the comparison of various possible machines in pumped hydro systems. Synchronous machines, fixed and variable speed induction machines and doubly-fed induction machines were compared for pump and turbine applications. The possible configuration and basic characteristics of each machine are described for pumped hydro application.
