摘　　要：常用提高低电压穿越能力的技术中,存在控制策略法算法较复杂而且不够可靠,Crowbar电路法电阻选取要求高、控制易失效、不能提供无功支持等问题。首先对国内外低电压穿越技术标准进行了概述,分析了当前主要低电压穿越技术研究情况;然后对储能技术的特点及其在低电压穿越技术研究中的拓扑结构、特性等进行了探讨;最后对基于储能技术的低电压穿越技术应用前景进行了分析和展望。Among the common technologies for improving the LVRT （Low Voltage Ride Through） abmty,tne control strategy method is complex and unreliable,while the Crowbar circuit method suffers for the difficult resistance selection,control failure and impossible reactive-power support. The LVRT technology standards at home and abroad are summarized and the current research status of main LVRT technologies is analyzed. The characteristics of energy storage technology,as well as its topology and features in the applications of LVRT technology,are discussed. The development trend of LYRT technology based on energy storage technology is analyzed and prospected.
