| 摘 要： | 目前在电力传输网络中普遍存在共享光纤虚拟保护环的情况,以实现完全保护,达到组网灵活、简单的目的.文章介绍了几种针对虚拟共享保护环的组网方案,并对其进行理论和应用效果的分析比较,提出了当复用段通过双节点带通道环,且两环在双节点间共用一对光纤时,建议采用虚拟通道SNCP保护,方法简单,组网灵活,能够实现断纤及节点失效保护,为电力传输网提供了较为简单、实用、安全的组网方式.

| Abstract: | Virtual sharing fiber protection ring is prevalent in current power transmission networks,which can achieve full protection,flexible and easy networking.This paper introduces several virtual sharing protection ring network schemes,as well as campares and analyzes their theoretical and application effects.We demonstrate that when the multiplex section brings channel ring through two-node and the two rings between the two-node share a pair of optical fibers,virtual channel SNCP protection is recommended.This method is simple and flexible for networking.It can realize broken fiber and node failure protection for power transmission network,providing a simple,practical and safe networking mode. |
