配电网单相接地故障零序全电流分析
摘要
通过对中性点不接地配电网单相接地故障时零序全电流的分析
得出了利用零序全电流的大小和方向进行故障选线的新方法。与传统的故障选线相比较
选线信号容易获得
并且是接地电流的全部信息。这对故障线路的识别、提高选线的准确率以及微机选线装置的开发是有利的。
Abstract
By analyzing the zero-sequence full current for single-phase grounding fault in isolated neutral distribution network
a new approach to determine the faulty transmission line is obtained. Compared with the conventional method based on the zero-sequence elementary frequency faulty current
it is available conveniently
being beneficial to the identification of faulty line and the development of micro-computer-based device of faulty line identification.
