摘要
随着智能电网的发展,未来电力系统通信业务将转向大颗粒IP业务,业务传输所需的带宽将迅速增长。针对电力系统通信业务对光通信网络的新要求,提出在电力通信系统中采用OTN、PTN技术的必要性。文章介绍了当前电力通信传输网的现状和存在的问题,提出OTN和PTN技术相结合的组网模式更适应电力系统通信业务IP化的需求。结合目前电力光纤通信网现状,论述了OTN和PTN在电力通信网中的应用方案。
With the development of smart grid,wider bandwidth is needed in power communication network since it will carry more IP services in the future.Based on the new requirement on power optical communication network,this paper discusses the necessity of using OTN and PTN technology.It introduces the situation and problems of current power communication network,and points out that the network mode of OTN＋PTN is more suitable for power communication IP services.The application scheme of OTN and PTN technology in power communication network is also discussed in the paper.
