基于无线自组织网络的配电网单相接地故障分段定位法的研究.pdf

摘 要

在 10KV 配电网单向接地故障检测方面，传统的方法是向故障线路注入某种电流
信号进行检测，由于线路分支较多，网络结构非常复杂，往往浪费了大量的人力物力。
本文提出基于无线自组织网的监控网络，通过在配电网上分布无线节点的方法实现对线
路的监控。无线节点将配电线路划分成若干个区域，称为段。分段定位法就是用无线节
点获取某一段的故障信息，如此大大减小了故障搜索的范围。论文分析了无线自组网的
关键技术，并通过采用单片机和无线模块完成了无线节点的构建。此方法能够很方便地
实现预期功能，具有广阔的应用前景。

ABSTRACT

For the single-phase ground fault examination of 10KV distribution, conventional
practice is to pour some kind of electric current signal into the faulty line and thus to carry on
the examination. However，massive manpower and resources are wasted because of multiple
line branches and complicated network architecture. The wireless monitoring network this
article proposed, which is based on Ad hoc net, implement the line's monitoring through the
wireless nodes distributed on the distribution networks. The distribution wire will be divided
into several regions by Wireless nodes, named as section. The subsection location method is
meaning of getting the fault information of particular section by wireless nodes, so the fault
search scope will be reduced greatly. The thesis analyzed the key technology of Ad Hoc net,
and accomplished the wireless node by MCU and wireless module。The anticipated function
could be implemented conveniently by this method, and there is a broad application prospect
of the system.
