摘　　要：根据实际运行中电力光传输网的复杂性,针对随机并发多链路故障场景,在传统主动定位算法的基础上,提出一种基于主动监测业务的故障定位算法,即主动融合算法。该算法首先预处理业务的告警信息,简化告警表;然后利用主动监测器,发送检测业务,最终精确定位多链路故障的位置。与传统的被动定位算法相比,主动融合算法可以提高定位准确率10%以上;与传统的主动算法相比,主动融合算法可以进行多链路故障的定位。仿真结果表明,主动融合算法定位时长在9 ms以内,定位准确率达到70%以上,能够满足电力光传输网的正常运行需求。In view of the complexity in practical operation of electric power optical transport network （EP-OTN）, according to the scene of stochastic concurrent multi-link failure and on the basis of traditional active failure location algorithm a multi-link failure location algorithm based on active monitoring service, namely the active fusion algorithm, is proposed. Firstly the proposed algorithm preprocesses the alarm information included in the business and simplifies the alarm table; then the monitoring service is sent by the active monitor; finally the multi-link failure is located accurately. Using the proposed active fusion algorithm the failure location accuracy can be increased by more than 10 percent than using traditional passive location algorithm. Simulation results show that using the active fusion algorithm the failure location time is less than 9 ms and the accuracy of failure location is higher than 70 percent, therefore the proposed active monitoring service based multi-link failure location algorithm can be suitable to normal operation of EP-OTN.
