摘要
针对电力通信网络的改造和优化问题,介绍了PTN(Package Transport Network,分组传送网)技术和电信级以太网技术的基本概念,对PTN技术支持下的电信级以太网技术在电力系统通信中的应用进行了可行性分析和探讨。结合目前电力光纤通信网现状,给出了构建电信级以太网的网络模型,从而使电信级以太网技术在现有SDH网络基础上建设新型的电力系统信息通信承载网成为可能,电信级以太网技术也将成为电力系统通信应用和发展的主流。
This paper analyses the present situation of power communication system.Aiming the optimization and upgrading of power communication network,it introduces PTN（Package Transport Network） and carrier-class Ethernet technologies,and analyses the feasibility of applying carrier-class ethernet supported by PTN in power communication system.Based on the current power optical fiber communication network,it puts forward a network mode of constructing a carrier-class Ethernet,which enable the application of carrier-class ethernet technologies to be used in existing SDH network to form a new type of power information and communication system.It points out that the carrier-class ethernet technologies will become the mainstream in power communication system.
