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。
According to the complexity of power optical transmission network in actual operation, aiming at stochastic concurrent multi-link fault scenario, a fault location algorithm based on active monitoring service is proposed based on the traditional active positioning algorithm, ie active fusion algorithm. The algorithm firstly preprocesses the alarm information of the business and simplifies the alarm table. Then, it uses the active monitor to send the detection service and finally pinpointing the position of the multi-link fault. Compared with the traditional passive location algorithm, the active fusion algorithm can improve the positioning accuracy by more than 10%. Compared with the traditional active algorithm, the active fusion algorithm can locate the multi-link fault. The simulation results show that the active fusion algorithm has a positioning accuracy of less than 9 ms and a positioning accuracy of more than 70%, which can meet the normal operation requirements of power optical transmission network.
