摘要/Abstract

摘要：

针对现有配电网单相接地故障定位技术存在的不足,借助于边缘计算和广域同步测量技术,提出一种新的故障定位方法。首先,依据单相接地特征论述了广域同步录波和配电网母线边缘计算两项关键技术的原理和装置设计要求。然后,通过相似性度量算法建立余弦相似度和Tonimoto系数算法模型,提出了实现新型故障区段定位的办法。最后,介绍单相接地智能定位系统工程应用情况,验证了此定位方法在实际配电网运行中真实可行,且精确度高。

关键词: 边缘计算, 广域同步测量, 故障定位, 相似性度量

Abstract:

Aiming at the shortcomings of the existing single phase ground fault location technology in the distribution network, a new fault location method is proposed with the help of edge computing and wide-area synchronous measurement technology. First, based on the characteristics of single phase grounding, the two key technical principles and device design requirements of wide area synchronous wave recording and distribution network bus edge calculation are discussed. Then, a cosine similarity and Tonimoto coefficient algorithm model is established by the similarity measurement algorithm, and a new method for locating fault sections is proposed. Finally, based on the engineering application of the single phase grounding intelligent positioning system, it is verified that the positioning method is realistic and feasible in actual distribution network operation with high accuracy.

Key words: Edge computing, wide area synchronous measurement, fault location, similarity measure
