在配电网自动化系统中,故障的快速定位系统通过配网自动化的发展和应用,提出了一种新的故障定位方案,即故障自动定位系统。文中阐述了系统的工作原理,将故障指示器技术与其他领域的新技术或主流的技术相结合,通过故障指示器检测故障信号,并将信号传送给通信终端,传输给主站,并利用GIS技术,实现配电网故障快速自动定位。分别对架空线路和电缆线路的故障自动定位系统进行了分析,有效地指导配电网故障自动定位系统的建设实施,为提高配电网的供电可靠性具有重要意义。
In the distribution network automation system, the rapid fault location system put forward a new fault location scheme through the development and application of distribution network automation, namely the fault automatic positioning system. This paper describes the working principle of the system, the fault indicator technology and other areas of new technology or mainstream technology combined with the fault indicator through the detection of fault signals, and the signal sent to the communication terminal, transmitted to the main station and the use of GIS Technology to achieve rapid automatic distribution network fault location. The automatic fault location system for overhead lines and cable lines are respectively analyzed to effectively guide the construction and implementation of automatic fault location system for power distribution network, which is of great significance to improve the power supply reliability of the distribution network.
