摘要
针对单相接地故障给配电网带来的危害,结合当前主流的单相接地故障定位方法,提出一种基于C型的行波故障测距法。同时为了提高对不同区段行波测距故障定位的准确性,引入了SVM算法对信号进行分类。最后通过仿真试验验证了该方案的可行性。
In view of the harm of single-phase grounding fault to the distribution network,a traveling wave fault location method based on C-type is proposed in combination with the current mainstream single-phase grounding fault location method.At the same time,in order to improve the accuracy of fault location for traveling wave location in different sections,the SVM algorithm is introduced to classify the signals.Finally,the feasibility of the scheme is verified by simulation tests.
