摘　　要：提出了风力机直接耦合压缩空气储能系统(wind drove compressed air energy storage,W-CAES),其优点是可以减少因风能的波动性和随机性而造成的风能浪费,采用风力机直驱压缩机的工作方式摆脱了压缩机对输入电能的依赖,更适应离网发电系统。建立了W-CAES系统模型,设计了风力机直驱的压缩空气储能系统参数,分析了风速、环境温度以及空气湿度对系统效率的影响。结果表明:在储气体积相同情况下,充气时间随风速的降低而增加,当风速为14、6 m/s时,充气时间分别为0.71、1.64 h;系统效率随环境温度和空气湿度的升高而略有降低;当环境温度分别为-30、40℃时,对应的系统效率分别为52.97%和52.08%;当空气的相对湿度分别为0和1时,对应的系统效率分别为52.27%和52.14%。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.
