Reservoir impoundment power generation device and impoundment method thereof

Abstract

The invention provides a reservoir impoundment power generation device and an impoundment method thereof. The reservoir impoundment power generation device comprises a reservoir, an impoundment unit and a power supply unit. The impoundment unit comprises a plurality of layers of impoundment tanks which are arranged at different heights, and each impoundment tank is provided with a drainage valve controlling drainage of the impoundment tank. A water injecting pipeline is arranged between the reservoir and the impoundment unit and communicates with the interior of each impoundment tank, and a water inlet valve is arranged in the position, corresponding to each impoundment tank, of the water injecting pipeline. The power supply unit is used for conveying water into each impoundment tank. According to the reservoir impoundment power generation device and the impoundment method thereof, the impoundment unit is of a hierarchical structure, and compared with a traditional impoundment device, when the impoundment unit is equally divided into ten impoundment tanks, under the condition of the same volume and height, work of the power supply unit is reduced by 45%, and energy consumption in the pumped storage process is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of pumped storage power generation, in particular to a water storage power generation device and a water storage method. Background technique [0002] my country began to introduce foreign "pumped storage power generation" technology and equipment in 2003, and then made further digestion and absorption to gradually implement localization. Pumped storage power generation can store water for flood control, store water in rainy seasons for use in water-scarce seasons, and can be used to adjust the load of the power grid to achieve peak shaving and valley filling. [0003] The existing pumped storage power generation device generally uses a water pump to pump water into a high reservoir at night, and discharges the water in the reservoir during the day, thereby driving a hydroelectric generator to generate electricity. Since the reservoir has a certain depth, and the water inlet pipe of the reservoir is general...

AI Technical Summary

Problems solved by technology

Since the reservoir has a certain depth, and the water inlet pipe of the reservoir is generally set above it, during the water storage process, the water pump needs to pump the water to the inlet pipe above the reservoir, and then the water body falls under the action of gravity To the bottom of the reservoir, the potential energy of the water body is correspondingly reduced, resulting in a waste of energy, and the greater the depth of the reservoir, the more energy is wasted
