Pump-Turbines |
 |
Since pumped storage power stations were constructed as a powerful and economical measure for the storage of electric power, various efforts have been undertaken to improve the economy and the reliability of these power stations.
Recent technology concerning single-stage pump-turbines has been explored and developed toward realization of higher head and larger machines.
Figure in the next page shows "Progress in Pumping Head of Pump-Turbines".
TOSHIBA's typical examples of the single-stage pump-turbines towards higher heads are;
