摘　　要：山西电力主干通信网2.5 G系统四纤自愈环完成改造后,为验证基于四纤自愈环的通道参数是否满足继电保护技术要求,制定了在运行四纤环上开通继电保护通道并与继电保护装置进行互联试验的方案。通过试验,模拟了继电保护通道在收发时延不一致的情况及四纤环纤芯中断情况下继电保护通道时延变化情况,试验结果表明基于四纤自愈环的继电通道在切换过程中不存在收发时延不一致的情况,满足继电保护通道技术要求。With the completion of 4F MS-SPRing transformation in Shanxi electric power 2.5 G backbone communication network, this article put forward test scheme to open the relay protection channel and then test with protective device interconnection on the operation of 4F MS-SPRing, which was to verify if the 4F MS-SPRing channel parameters could meet the requirements of relay protection technology. Through several sets of experiments, we stimulated the relay protection channel with the transceiving delay inconsistency and 4F MS-SPRing fiber interruption of relay protection channel time delay changes. It showed that, based on the four fiber self-healing ring, relay channel switching did not exist in the course of transceiving delay inconsistency, which met the technical requirements of relay protection channel.
