摘要

小电流接地系统的单相接地故障类型识别对提升配网运行的安全性和可靠性具有重要意义。首先，根据故障的稳态和暂态特征，对单相接地故障进行了多层次递进式分类和定义；其次，提取不同类型故障的电气量特征，建立小电流接地故障类型识别模型；最后，以现场的录波数据对文中提出的故障类型识别模型进行验证。验证结果表明，所提方法能够有效地识别接地故障类型，有利于提高小电流接地故障处理的针对性。

Abstract

The identification of single-phase earth fault in non-solidly earthed network is of great significance for improving the safety and reliability of distribution network operation. Firstly

based on the steady and transient characteristics of recorded fault data

a multilevel hierarchical classification is made of single-phase earth fault and the definitions of different faults are made. Secondly

the electrical characteristics of different types of fault are extracted and a single-phase earth fault type recognition model is established. Finally

the proposed fault type recognition model is verified by the recorded data on the scene. The test results show that the proposed method can effectively identify earth fault type

which is beneficial to improve the pertinence of fault handling in non-solidly earthed network.
