Abstract

The invention provides a wind-driven water pumping energy storage system. The energy storage system comprises a fan head, wherein the cabin of the fan head is internally provided with a change gear set, which is used for transferring power to a transmission rod component, and the transmission rod component extends into the interior of a tower barrel; the tower barrel is internally provided with water tanks, a fan foundation is internally provided with a tower bottom pool and a water suction pump, and the water suction pump is used for pumping water to a first water tank group through the transmission between the water tanks; through a support transmission water level control water pumping system of the uppermost water tank of the first water tank group, the water in the first water tank group is pumped into the a second water tank group, and the above operation of the structure is repeated until the water in the second water tank group is pumped into the first water tank group througha support transmission water level control water pumping system of the uppermost water tank of the reciprocal second water tank group; each water tank is connected with a main water outlet pipe, and acontrol valve is arranged on each water outlet pipe; the water outlet pipes are connected with the water inlet of a water wheel generator to generate power; and through the connection of the water outlet pipes with the water inlet of a reverse osmosis seawater desalination system, the potential energy of the water in the tower barrel can be used for performing seawater desalination. By adopting wind-driven water pumping energy storage system, the energy storage technology can be applied to a wind power generation system and a seawater desalination system.

Description

technical field [0001] The invention relates to the technical field of wind energy utilization, in particular to a wind power water pumping energy storage system. Background technique [0002] Wind power generation has been greatly developed all over the world. However, due to the fluctuation and intermittency of the output power of wind power generation due to changes in weather conditions, it is difficult to connect a large area to the power grid. In recent years, large-scale " Wind curtailment has seriously affected the development of wind power. In order to enhance the stability of the wind power generation system and ensure continuous power supply to the load, it is becoming more and more important to use wind power generation energy storage technology. [0003] The pumped energy storage in the prior art is a form in which electric energy is converted into gravitational potential energy and stored when water is pumped from the lower reservoir to the upper reservoir dur...
