摘　　要：介绍了风电并网所引起的电压闪变及其产生机理,指出了风速、塔影效应等因素对电压闪变的影响,风电并网点选择需考虑SCR和R/X对电压闪变的影响。依靠补偿、储能设备可以抑制电压闪变,总结了6种抑制电压闪变的储能补偿设备的工作特性、性价比、优缺点及使用状况。The voltage flicker caused by wind power grid and its creation mechanism were introduced,and the factors such as wind speed,tower shadow effect on the voltage flicker were pointed out.The wind power site selection should consider the influence of SCR and R/X on the voltage flicker which provided reference for wind farm site design.The compensation,energy storage equipment could inhibit the voltage flicker,six energy storage and compensation equipment and their operating characteristics,price-pertormance ratio,advantages and disadvantages and use condition were summarized.The prospect for the treatment of voltage flicker follow-up work was also presented.
