Design and Development of Automatic Position Software for Single Phase Grounding Fault in Electric Power Distribution Network

针对目前单相接地故障自动定位技术存在的不足,基于信号注入的基本原理,以单相接地故障自动选线和定位单元为基础,设计并开发了单相接地故障自动定位软件系统,该系统以VS.NET为开发平台、基于SQL数据库的数据共享编程和面向对象的C#开发语言实现。在煤矿供电系统发生单相接地故障后,通过获取选线结果和分散安装的故障定位单元的判断结果,能够自动判断出故障所在区段,有助于快速、准确排除故障,恢复煤矿系统供电。

According to the shortage of the present research on the automatic positioning technology of the single phase grounding fault,based on the basic principle of the signal injection,the automatic selected line and positioning element of the single phase grounding fault as the base was applied to design and develop the automatic positioning software system of the single phase fault.The system was achieved taking the VS.NET as the development platform and based on the data joint sharing programming of the SQL database and the C# development language of the objected-oriented.When the single phase grounding fault occurred in the mine electric power supply system,the selected line results and the judgment results of the separated installation fault position element obtained could automatically judge the section of the fault occurred and would be favorable to rapidly and accurately shoot the faults and recover the mine power supply system.
