How to increase water head variation in pumped storage power station?
In order to increase the variation of water head in the design of a pumped storage power station, a pumped storage power station using a virtual constant pressure tank is proposed in this paper. The limitation of the range of water head change can result in wasted reservoir capacity and limit daily power generation.
What is the structure of a power station?
The structure of a pumped storage power plant includes an upper reservoir and a lower reservoir, which form the first potential energy. The virtual constant pressure pool and the low-pressure pool constitute the second potential energy. The hydraulic transmission mechanism is composed of a number of components, including a turbine, a generator, and a pump.
