Conclusions
-
1.
The energy-storage hydroelectric station (ESHES) can provide a 1.5–2-fold increase in peak capacity with a simultaneous threefold decrease in daily fluctuations of the water level in the lower pool.
-
2.
A decrease in the length of the concrete structures located in the river channel (especially the length) of the powerhouse) reduces the consumption of concrete for the ESHES in comparison with the HES, which compensates for the cost of constructing the additional structures of the ESHES.
-
3.
Unlike the HES, the ESHES operates in a sharp-peak regime and also during passage of flood waters.
-
4.
Contrarotating pump-turbines are best suited for an ESHES because of various combinations of heads on its turbine and pump parts.
-
5.
With increase in the speed of multistage hydraulic machines their placement depth decreases and the cost of the powerhouse is reduced.
