电力通信系统中的SDH自愈环组网及其应用探讨

Discussion about the construction and application of SDH self-healing ring in electric power communication system

SDH环形网络因其具有自愈能力的优点,常常用于电力系统中继网和重要的长途骨干网的建设,因而如何更好地解决环网的安全性问题则至关重要。文章简要介绍了基于SDH传输机制的自愈环保护系统,包括基本概念、工作原理、性能比较以及应用范围。具体阐述了SDH自愈环组网应用中存在的一些实际问题,并探讨了相应的技术措施和解决方法。

SDH ring network is always used in electric power system to construct the relay network and important long-haul network because of its advantage of self-healing, it is necessary to solve the safety problem. This issue introduced the protection mechanisms based on the self-healing ring, including the basic concept, working principle, comparison of functions and the scope of application. At last, this paper analyzed the actual problems in constructing the SDH self-healing ring, and then discussed the technique measure and solution schemes.
