The invention discloses a compressed air energy storage method. The compressed air energy storage method comprises the following steps: wind in a certain wind speed range blows a vertical impeller ofa wind power air compressor to rotate, and the vertical impeller drives a planetary piston compressor with a plurality of cylinders to operate through a transmission shaft; air pressure in a compressed air storage tank is lower than rated working air pressure, a pressure relief valve of the planetary piston compressor is closed, and gas is pumped into the compressed air storage tank; and air pressure in the compressed air storage tank reaches the rated working air pressure, the pressure relief valve of the planetary piston compressor is opened, and air pumping into the compressed air storage tank is stopped. The invention also discloses the wind power air compressor. According to the compressed air energy storage method and the wind power air compressor, energy storage of compressed air isrealized through a mechanical direct transmission mode; and the structure is simple, the cost is easy to control, and the maintenance and the maintenance are convenient.
Description
technical field [0001] The invention relates to the field of power systems, in particular to a compressed air energy storage method and a wind-powered air compressor. Background technique [0002] Wind power is a clean renewable energy source, mostly used for power generation, but large-scale storage of electric energy is a big problem and the cost is high. [0003] Compressed air energy storage is a relatively advanced energy storage method, which uses the compressibility of air to store energy. However, the existing compressed air energy storage equipment mostly uses electric compressors for gas compression, and the energy conversion efficiency is low. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a compressed air energy storage method and a wind-powered air compressor, which realize the energy storage of compressed air through mechanical direct transmission; the structure is simplified, the cost is easy to c...
