摘　　要：随着电力光传输网的不断演进,电力通信网网络结构越来越大,越来越复杂。文章针对现有的生存技术和网络常出现的故障,结合对网络生存性发展的需求,分析了1+1、1:1等线性保护和P-Cycle保护方案,同时详述了OTN网络的保护与恢复。随着电网业务的快速发展,IP业务呈现快速增长,OTN网络多域的保护恢复成为研究重点。With the development of power optical transmission network, the network structure is more and more big, more and more complex, according to the common network faults and existing survival technology, combined with the development needs of network survivability, we analyze 1 ＋ 1 and 1： 1 linear protection and P-Cycle protection scheme, and describe the protection and restoration of OTN network. With the rapid development of grid service, IP service presents the fast growth, the protection ofOTN multi domain network restoration has become a hot topic.
