摘　　要：以往馈线自动化技术中的监控终端,在判定故障线路时极易引发非故障线路断电,为此,引入GPRS(General packet radio service,通用分组无线服务)技术研发出一种配电网馈线自动化故障定位技术。根据无方向性馈线故障定位算法,结合表征各单元间邻接关系的单元邻接表,定位出馈线故障所属区段,采用GPRS通信模式实现信息传输与共享,基于GPRS通信模式与馈线监控终端的联邦式架构建立GPRS通信模块的协同故障防护策略,通过GPRS监控终端模块,实现故障定位自动化。以某县乡级配电网模拟故障发生,验证得出GPRS通信在实现自动化方面更具可行性,且该项技术有效性与适用性较强。In the past,the monitoring terminal in the feeder automation technology is very easy to cause the power failure of the non-faulty line when determining the faulty line.For this reason,the GPRS technology is introduced to develop a feeder automation fault location technology for the distribution network.According to the non-directional feeder fault location algorithm,combined with the unit adjacency table that characterizes the adjacency relationship between the units,the section of the feeder fault is located,and the GPRS communication mode is used to realize information transmission and sharing,based on the federation of the GPRS communication mode and the feeder monitoring terminal.The architecture establishes a collaborative fault protection strategy for the GPRS communication module,and realizes the automation of fault location through the GPRS monitoring terminal module.Using a county and township-level distribution network to simulate the occurrence of a fault,it is verified that GPRS communication is more feasible in realizing automation,and the technology is more effective and applicable.
