基于无线传输的电缆局部放电定位及监控技术研究

Based on the Wireless Transmission of Cable Partial Discharge Positioning and Monitoring System Research

随着我国电力行业的高速发展,交联聚乙烯绝缘电力电缆(XLPE电缆)成为了当前最流行的输电电缆,但电缆中的局部放电严重的威胁电缆运行安全。因为XLPE电缆局部放电检测定位技术的研究处于初级阶段,XLPE电缆的安全运行经常受到电缆中局部放电的严重威胁。因此本文针对XLPE电缆的局部放电检测定位问题进行研究,提出一种基于无线传输的电缆局部放电定位和监控技术(Wireless-PDLAM)。通过Wireless-PDLAM技术将各个终端检测点的局放量信息传输到协调器网关,协调器网关对采集到的所有数据进行处理获得定位信息并上传网络供监测人员分析。本研究采用多点无线方式采集局部放电信息达到定位效果;使用SocKet技术上传到网络服务器;监测人员远离放电电缆进行数据查看分析极大的减小电缆对人体的辐射。

With the rapid development of China＇s electric power industry,XLPE insulated power cables（XLPE cable）have become the most popular transmission cable.But since the research of XLPE cable partial discharge detection and location technology is at the primary stage,in the safe operation of XLPE cables is often subject to serious threat of cable partial discharge.Therefore,this paper studied the problem of partial discharge detection and location of XLPE cables,and proposed a cables partial discharge location and monitoring technology based on wireless transmission（Wireless-PDLAM）.Wireless-PDLAM technology will transmit information of partial discharge detected by each terminal point to the coordinator gateway,the coordinator gateway process all the data collected to obtain location information and upload to the network for monitoring staff to analysis.This study has several advantages as following：firstly it adopts a multi-point wireless to collect partial discharge and achieve results of location;second it uses Socket technology to upload data to a web server; third monitors are away from the discharge cables to analysis data so that it reduces the radiation on the human body greatly.
