Problems solved by technology
However, batteries usually have low charging and discharging efficiency, fast attenuation, short service life, small storage power, and extremely strict requirements for storage and adjustment of batteries, resulting in high costs
Moreover, the disposal of waste batteries has a great impact on the environment
[0006] In addition, some energy, such as heat or cold, will be generated during the process of generating electricity by wind turbines, but these energy sources are not currently recycled, resulting in a waste of resources

Embodiment Construction
[0052] The specific implementation manner and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0053] to combine figure 1 It can be seen that an air energy storage power generation system based on wind kinetic energy includes a tower 1 and a wind wheel 3 arranged on the top of the tower 1, and a wind cabin 2 is also arranged on the top of the tower 1. In the wind cabin 2. There is a screw compressor 4 inside. The wind wheel shaft 31 of the wind wheel 3 penetrates into the inside of the fan cabin 2 and drives the screw compressor 4. The screw compressor 4 delivers compressed air to the high-pressure gas storage device 5. The compressed air output by the high-pressure gas storage device 5 drives the turbo expander 7, and the turbo expander 7 drives the rotor generator 6 to generate electricity. The AC input terminal is connected, the DC output terminal of the AC-DC conversion module 13 is conne...

The invention discloses an air energy storage power generation system based on wind power kinetic energy. The system comprises a tower, a wind wheel, a fan cabin, a heat energy recovery mechanism, a cold energy recovery mechanism and a controller. The wind wheel and the fan cabin are arranged on the top of the tower; a screw compressor is arranged in the fan cabin; a wind wheel shaft of the wind wheel penetrates through the inner part of the fan cabin to drive the screw compressor to convey compressed air to a high pressure air storage device; the high pressure air storage device outputs air to drive a turbo expander to drive a rotor generator to generate power; electric energy output by the rotor generator passes through an AC-DC conversion module and a DC-AC conversion module and is merged into a power grid; the heat energy recovery mechanism is used for collecting heat energy generated by the compressed gas; the cold energy recovery mechanism is used for collecting cold energy generated by power generation; the controller is used for controlling gas compression and gas power generation. The system provided by the invention has the beneficial effects that the system generates power in real time as required; the whole gas compression and gas emission system is simple and compact in structure, easy to maintain, long in service life, low in cost and environmental-friendly and pollution-free.
Description
technical field [0001] The invention relates to the technical field of wind storage power generation, in particular to an air energy storage power generation system based on wind kinetic energy. Background technique [0002] A wind turbine is an electrical device that converts the kinetic energy of wind into electrical energy. Wind energy belongs to clean energy, and there is no pollution to the natural environment in the process of converting wind energy into electrical energy. Therefore, with the gradual improvement of energy conservation and environmental protection requirements in our country, wind power generation has been more and more widely used, especially in the north and high regions of our country. Altitude areas are rich in wind resources, and wind power generation has been vigorously promoted and applied in these areas. [0003] However, wind power generation also has obvious shortcomings. Among them, the most prominent one is the unstable wind speed. During t...
