摘要
针对小电流接地系统单相接地故障选线的研究现状,提出了基于非故障相暂态电流的单相接地故障选线的方法。该方法利用小波变换分析非故障相暂态电流,通过对暂态电流模极大值数值的比较来实现故障线路的选择。ATP仿真分析的结果表明,该方法准确可靠。
Aiming at the condition of fault location for feeder single-phase-to-grounded in non-effective grounding distribution systems, a new method using the transient current component of non-fault-phase in faulty feeder to realize fault location is presented. The possibility from the angle of singularity detection is tested. The results of ATP simulation prove that this method is correct.
