风力机直接耦合压缩空气储能系统及其建模分析
Modeling and analysis of novel wind-drove compressed air energy storage system
摘要
Abstract
A wind-drove compressed air energy storage(W-CAES)system is proposed,its main advantage is that it can reduce the waste of wind energy caused by the fluctuation and randomness of wind energy.The direct-driven compressor of wind turbine gets rid of the dependence of compressor on the input electricity,which is more suitable for off-grid power generation system.The model of the W-CAES system is established,the parameters of the wind turbine direct-drive compressed air energy storage system are designed,and the effects of wind speed,ambient temperature,and air humidity on efficiency of the system are analyzed.The results show that,the filling time increases with the decrease of wind speed with the same storage volume,and the filling times are 0.71 h and 1.64 h when the wind speeds are 14 m/s and 6 m/s,respectively.The system efficiency decreases slightly with the increase of ambient temperature and air humidity.When the ambient temperatures are-30℃and 40℃,the corresponding system efficiencies are 52.97%and 52.08%,respectively.When the relative humidity of the air is 0 and 1,the corresponding system efficiencies are 52.27%and 52.14%,respectively.关键词
