AI Technical Summary
In conventional pumped storage facilities, the construction and maintenance costs of the underground power chamber are high, especially for small-scale installations. Furthermore, the existing reversible pump turbines require deep excavation and are too costly to construct, resulting in very few small-scale pumped storage facilities.
The reversible pump-turbine is positioned low enough below the tailrace height using wellbore diameters of 1 to 3 meters to suppress cavitation. A simple and inexpensive wellbore configuration is used, combined with a submersible electric generator and removable manifold, reducing reliance on an underground power chamber. Standard hydraulic design and multi-stage machine stacking are used to accommodate different head conditions.
It reduced the construction cost of the equipment, improved efficiency, allowed for the installation of small pumped storage facilities in more sites, and increased the number of projects through the use of standard components, reducing the need for underground power rooms.
