Description
Technical Field
The invention belongs to the technical field of water supply systems of pumped storage power stations, and particularly relates to an automatic water supply system without consuming electric energy and a water supply system structure capable of saving electricity.
Background
At present, in a pumped storage power station, electric power in a power grid at a load valley is utilized, water is pumped from a lower reservoir to an upper reservoir for storage, and water is discharged to return to the lower reservoir for power generation when the power grid is loaded at a peak. The pumped storage power station can convert redundant electric energy when the load of a power grid is low into high-value electric energy during the peak period of the power grid, but the phenomenon of resource waste exists, according to theoretical calculation, the pumped storage power station needs to consume four degrees of electricity at least every three-degree electricity generation, and if the loss of a power transmission line is added, the electric energy of 1/3 is actually wasted. The existing hydropower station utilizes the fall of the concentrated natural water flow of the building to form a water head, collects the flow of the natural water flow and converts the concentrated water energy into electric energy. The hydropower station of the reservoir considers the safety problem of hydraulic buildings, the water level difference for generating electricity is constant, and the generating capacity is limited by the water level difference.
