摘　　要：随着智能电网的建设,电力传输网络承载的业务逐渐增长,网络规模也逐渐壮大,对光纤资源提出了新的要求。目前,地市级电力通信骨干传输网主要采用具有较低传输带宽的同步数字体系(Synchronous Digital Hierarchy,SDH)技术,其极大地限制了传输网的发展步伐。基于此,建设具有大颗粒、高传输带宽的光传送网(Optical Transport Network,OTN)将为电力通信传输网带来新的发展前景,同时采取有效的手段来提升骨干传输网络的稳定性也成为保障电力安全稳定运行的重要内容。With the construction of smart grid,the business carried by power transmission network is gradually increasing,and the network scale is also gradually expanding,which puts forward new requirements for optical fiber resources.At present,Synchronous Digital Hierarchy(SDH)technology with low transmission bandwidth is mainly used in the backbone transmission network of prefecture-level power communication,which greatly limits the development of transmission network.Based on this,the construction of Optical Transport Network(OTN)with large particles and high transmission bandwidth will bring new development prospects for power communication transmission network,and at the same time,taking effective measures to improve the stability of backbone transmission network has become an important content to ensure the safe and stable operation of power.
