压缩空气储能系统节流效应研究
Research on Throttling Effect of Compressed Air Energy Storage System
摘要
Abstract
In order to solve the variable conditions of the compressed air energy storage system during the release process,a throttling regulator valve device is proposed to be provided at the outlet of the gas storage to ensure efficient operation of the air expander under the design conditions. The thermodynamic model for the throttling process was built to research the influence law of the physical properties of the real air on the effect of the throttle valve with focus on the influence law of the throttling regulator valve on the energy conversion efficiency of the system. The research results show that addition of the throttling regulator valve in the compressed air energy storage system will bring additional irreversible loss,but can solve the problem of its operating conditions,can improve the efficiency of the air turbo expander,and has very small influence on energy conversion efficiency of the original system. The research results have certain guiding significance for engineering application of the compressed air energy storage system.关键词
