摘　　要：对广域方向纵联保护算法进行深入研究,得到一种广域继电保护算法,该算法的原理是对正序故障方向进行比较:利用智能电子设备IED(Intelligent Electric Device,IED)的定位,将线路、母线组成IED关联域。在这个系统出现故障时,通过IED在关联域内对故障信息的采集和共享,结合文中定义的故障判别原则,可以得出发生故障的位置。通过IED设定的相应策略,快速排除故障。To deeply research direction longitudinal wide-area protection algorithm, get a wide-area relay protection algorithm, the principle of the algorithm is of positive sequence fault direction, use of intelligent electronic devices positioning, will line, busbar lED correlation domain. In the system failure, through the IED in correlation domain of failure information collection and sharing, combined with the definition of fault principle, you can find the fault location. By setting up corresponding strategy of IED, quick troubleshooting.
