SDH技术在电力通信接入网中的应用

Application of SDH technology in the electric power communication access network

根据电力系统通信业务的特点 ,分析目前电力通信网中业务传输存在的问题。文中还论述了将类似于ABB公司FOX5 15 / 5 12开发思路的SDH用户接入设备 ,综合应用于电力系统通信的接入网 ,不但保证了通信的高可靠性、高可用性 ,还降低了造价 ,以及设备配置简洁、运行管理也简单方便。并且 2 2 0kV的线路保护信号 ,在线路自身不具备OPGW的条件下 ,也能利用SDH自愈网实现可靠传输。

According to the communication characteristics in electric power communication system and the analysis on the problems occurred in power communication system,this paper presents that integration of the design idea of such a SDH access equipment as ABB's FOX515/512 into the electric power communication access network will not only guarantee the high dependability and high usability in communication but also reduce the costs and simlify the equipment configuration and make operation management easy as well.Using the SDH's self-healing network can also realize the reliable transmission of the line protective signals on 220 kV even without OPGW equipped for the line.
