摘　　要：分析了风电接入配电网对电流保护的影响,提出了自适应电流速断保护方案,并对其实现过程中的关键点进行了论述。RTDS试验结果表明,对于风电接入的配电网,自适应电流速断保护能适应系统运行方式和故障类型的变化,保护范围稳定,具有很好的适用性。The influence of wind power access distribution powernetwork on current protection was analyzed.Ascheme of an adaptive current quick-break protectionwasproposed. Then, the three key points duringrealization the theorywas discuss. Finally, the result of RTDS test showed that the adaptive current quick-break protection couldnot only fit to the running mode of the system and the various fault typesbut alsohad a stableprotective range of line length, and it was good application in thedistribution power network.
