摘要
随着电力业务的发展和网络规模的扩大，现有传送网络组织结构越来越复杂。在以环网组织结构为主的省内、本地传送网申，多环间互连互通的情况已经非常普遍。文章将围绕如何在SDH环间互通结构下进行业务组织并满足业务和用户的要求进行论述，最后结合电网保护业务所做的互通实验结果进行讨论，提出SDH环间互通结构具有很好的优势，能够满足电网业务的需求。
Nowadays, with the development of service and the extension of network scale, the structure of transmission network becomes more and more complex. In provincial and local transmission network which uses ring network as ita main structure, it is common that several rings need to communicate with each other. The main problem that we are concerned is how to deal with operation in SDH ring structure . This article will circumfuse this problem, and discuss the results of experiment about protection operation of power gird, and propose the advantage of the connection of SDH rings which can satisfy the need of power grid.
