摘　　要：基于SDH的第3代MSTP技术正在快速发展,它不但继承了SDH技术的高可靠性与强大的网络生存能力,还为RPR over SDH等数据业务提供灵活的接入方式和可靠的传输保障。建设MSTP网来传输电力生产信息与部分数据业务信息,是未来电力系统通信网发展的趋势。文章根据电力系统业务的特殊性与通信设备特点,探讨采用MSTP技术组建骨干网的几种组网方案,通过技术上的充分比较,选择出了最优方案,并对该方案的保护方式、节点设置、设备配置等方面进行研究。The SDH based third generation MSTP technology is quickly developing. Not only it has the advantages of network securi- ty and powerful viability inherited from SDH technology, but also it provides flexible access mode and stability transmission for data service, such as RPR over SDH. Constructing MSTP network to transmit electric power information and data service information is a trend for electric power communication development in the future. Based on the particularity of services in electric power system and characteristics of communication equipment, this paper discusses several schemes of constructing backbone network based on MSTP technology, and via the comparison in technique an optimum scheme is given out, the protecting manner, node setting and equipment configuration are discussed.
