MSTP(基于SDH的多业务传送平台)设备作为电力通信网的现行主力传输设备，承载着电网远程监视和控制的关键数据。笔者利用SDH原理实现了异种光传输设备间各种业务的互联互通，通过以太网通道解决了主站网管监控站端独立网元的问题，并总结了SDH基本传输原理、SDH互联互通条件，以最低成本成功实现了不同光传输设备网络的融合，有效提升了电力通信网络的安全运行水平。

As the current main transmission equipment of the electric power communication network, MSTP (multi-service transport platform based on SDH) equipment is carrying the key data for remote monitoring and controlling power grid. SDH principle was used to achieve the interconnection and interworking of various communication services between different kinds of optical transmission equipment, the problem of distal independent element’s remote monitor and controlling in central station was solved through Ethernet channel, the basic transmission principle of SDH and the condition of interconnection and interworking were summarized, and the fusion of different optical transmission equipment networks was realized with the lowest cost. The safety level of power communication network was improved effectively.
