配网单相接地故障模拟试验平台的研究与实现

摘要

By software simulation and distribution network simulated experiment, this paper studys and builds a single-phase to ground fault simulated experiment platform,which consists of different kinds of equivalent length distribution lines based on lumped parameters of PI type circuit model and different kinds of neutral grounding modes. The platform provides a realistic test and detection methods of dis⁃tribution network for accurate traveling wave fault location research and related product development.%通过仿真试验和配网模拟试验，研究并实现以线路集中参数元件π型电路模型为基础，搭建不同类型等值长度的配电线路，结合不同的中性点接地方式，组成配电网络单相接地故障模拟平台，为行波精确故障定位研究和相关产品开发提供了接近实际配电网的试验和检测手段。
