摘要
随着配电网规模的逐渐扩大,线路数量与分支逐渐增多,接线方式更加复杂,造成接地故障定位复杂,为了快速准确实现配电网接地故障定位,尽快恢复电网正常运行,设计并实现一种高精度配电网接地故障定位系统,该系统主要由处理模块、无线收发模块、海量存储模块、GPRS模块等构成,分析了所设计配电网接地故障定位系统的运行原理,通过Visual C++中API函数与数据库开发了配电网故障定位系统的三个功能层,给出后台软件控制流程,设计配电网接地故障定位系统软件,给出配电网接地故障定位系统中的部分C语言代码。实验结果表明,所设计配电网接地故障定位系统具有很强的实用性和可靠性。
With the gradual expanding of power distribution network scale,the number of power line and branches are increased gradually,and the wire connection mode becomes more complex,which make the earth fault location complex. To quickly locate the earth fault of the power grid and recover the normal operation,a high-precision earth fault location system for power distribution network was designed and realized,which is mainly composed of processing module,wireless transceiving module,mass storage module,GPRS module,etc. The operation principle of this system is analyzed. The three functional layers of this system were developed with database and API function in Visual C＋＋. The software of this system was designed. The backstage software control process and part C language codes of this system are given. The experimental results show that the designed earth fault location system for power distribution network has strong practicability and reliability.
