Embodiment Construction

[0014] The pumped storage power station includes a reversible pump-turbine (there are two working conditions, the pump working condition and the turbine working condition), an upper reservoir and a lower reservoir, the schematic diagram of which is attached figure 2 shown. During the low load period, the reversible pump turbine operates in the pump mode, using the excess electric energy to pump the water from the lower reservoir to the upper reservoir, and converts the electric energy into water energy for storage; during the peak load period, the reversible pump turbine operates on the turbine In the working condition, the water level difference between the upper and lower reservoirs is used to generate electricity, and the water energy is converted into electrical energy.

[0015] Seawater desalination adopts reverse osmosis membrane method, and the device diagram is attached image 3 shown. The device consists of a water intake system, a water feed pump, a multi-media fi...

Abstract

The invention discloses a wind-light supplementary power generating energy storing device which comprises a wind machine, a photovaltaic array, a controller and a storage battery, wherein the wind machine, the photovaltaic array and the storage battery are all connected with the controller; the controller is connected with a pumped storage power generation device which comprises a lower reservior, an upper reservior and a pipeline used for connecting the upper reservior with the lower reservior; the pipeline is provided with a reversiable water pump turbine; and the reversiable water pump turbine is provided with a first working condition that the water in the lower reservior is pumped into the upper reservior and a second working condition that the water in the upper reservior flows intothe lower reservior. Compared with the prior art, the energy storing device provided by the invention has the advantages that pumped storage can be used for partially replacing a storage battery for energy storing, the defects such as short service life, high cost, pollution and the like of the storage battery are overcome, simultaneously the reliability and stability of a system can be improved,and the device is environment-friendly.

Description

technical field [0001] The present invention relates to the technical fields of wind and solar complementary technology, wind power generation technology, solar power generation technology, pumped storage technology, seawater desalination technology, high-efficiency intelligent control technology, etc., and specifically relates to a power generation device combining wind power generation and solar power generation complementation and pumped storage . Background technique [0002] In many remote islands in my country, the power grid is difficult to reach. Most areas use diesel engines to generate electricity. With the shortage of oil and the rise of oil prices, the cost of power generation has risen rapidly. The shortage of electric energy has seriously restricted the economic development of these areas and the daily life of residents or garrisons. Life. And these areas are often rich in renewable energy, such as solar energy, wind energy, etc., which provide good innate con...
