摘要
提出一种振荡过程中进行故障测距的新方案，即运用模糊模式识别的方法，自动搜索线路两端电源电势夹角δ＝０°的时刻，并在这一时刻附近进行故障测距，经使用电磁暂态程序ＥＭＴＰ进行仿真计算，证明该方法是有效的。
A new algorithm about the fault location during the power swing is present.This algorithm can automatically search the time When the power sources at two ends nearly have the same phase with the method of fuzzy pattern recognition, and the fault lacation is calculated at this the. The digital sedation with EMTP shows that this method is valid.
