Compressed air energy storage system and offshore converter platform with compressed air energy storage function

Abstract

The invention relates to a compressed air energy storage system and an offshore converter platform with a compressed air energy storage function. The invention aims to overcome the problems of high randomness and insufficient stability of large-capacity wind power output caused by the fact that large-scale wind power is sent out through a converter station. According to the technical scheme, the compressed air energy storage system is provided with an air storage tank, a plurality of air compressors, a plurality of gas turbines and a power generator / motor which can drive the air compressors towork and can be driven by the gas turbines to generate power; the air compressors are sequentially connected in series, and air outlets of the air compressors connected in series are in pipeline connection with the air storage tank sequentially through an air compressor air outlet pipe valve, a cooler and an air storage tank air inlet pipe valve; the gas storage tank is sequentially connected with a plurality of gas turbines sequentially connected in series through a combustion chamber gas inlet pipe valve, a combustion chamber and a gas turbine gas inlet pipe valve pipeline. The invention isapplicable to the technical fields of green energy power generation technology and marine resource comprehensive application, and is particularly applicable to the fields of new energy such as offshore wind energy and the like and marine ranch aquaculture.

Description

technical field [0001] The invention relates to a compressed air energy storage system and an offshore converter platform with the compressed air energy storage function. It is suitable for the fields of green energy power generation technology and comprehensive application technology of marine resources, especially for new energy fields such as offshore wind energy and the field of marine pasture aquaculture and aquatic products. Background technique [0002] In recent years, marine new energy technologies such as offshore wind power generation have developed rapidly in my country. In addition to the rapid construction of offshore wind farms, COSCO wind farms are also gradually under construction. As offshore wind farms become farther and farther away from the shore, due to the limitations of transmission distance, capacity and economy, the traditional power transmission method suitable for offshore wind farms, which is suitable for offshore wind farms, is no longer able to...
