Research On The Subsection Location Method About Single-phase Ground Fault Of Distribution Network Based On Ad Hoc Net

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.
