摘要
电力系统的发展乃至智能电网的建设,要求对现有电力传输网进行优化。简要介绍了作为电力传输网主要网络的电力同步数字体系(SDH)传输网的网络结构以及对其性能的要求。通过对目前电力SDH传输网的电力通信业务存在问题的分析,提出了电力SDH传输网的优化原则,优化流程和内容。
The development of power system and construction of smart grid require to optimize the current transmission network.The structure and function requirements of the synchronous digital hierachy（SDH） as main part of the transmission network are briefly introduced.Through the analysis on the existing problems in communication system of SDH transmission network,the optimizing principle,procedure and content of SDH transmission network are proposed.
