摘要：针对东北地区电力业务特点及骨干传输网现状•在充分利用现有光缆、设备的基础上，提岀了省际骨干传

输网、省级和地市骨干传输网规划原则。东北地区省际骨干传输网以特高压和500 kV 光缆为骨干，采用双网建

设，构建跨省“田”字型网络拓扑结构，骨干网带宽为10 Gbit/s 。省级骨干传输网以220 kV/500 kV 光缆为骨干，采

用双环网建设，骨干网带宽为10 Gbit/s 。地市骨干网作为省级骨干网的接入网，以66 kV/220 kV 光缆为骨干，选

取地市公司及第二汇聚节点作为省级骨干网和地市骨干网的互联节点，互联带宽为10 Gbit/s 。地市骨干网重要站 点设备双重化配置•实现66 kV/220 KV 变电站的全覆盖。关键词：智能电网；网络规划；骨干传输网

Abstract : According to the power business and the current status of backbone transmission network in northeast

China,the planning principles of interprovincial backbone transmission network , provincial and municipal backbone transmission network are formulated on the basis of making full use of existing equipment. Northeast interprovincial

backbone transmission network uses UHV and 500 kV optical cables as their backbones ・ adopts double-network

construction, constructs interprovincial "Tian" shape in the Chinese word as the network topology, and the back

bone network bandwidth is 10 Gbit/s. The provincial backbone transmission network uses 220 kV/500 kV optical fiber cable as the backbone » adopts double-loop network construction, and the backbone network band width is 10

Gbit/s. The muni-cipal backbone network is the access network as the provincial backbone network, with 66 kV/ 220 kV optical cable as the backbone, and the municipal company and the second aggregation node are selected as the interconnection nodes of the provincial and the municipal backbone network ・ with the interconnection bandwidth of

10 Gbit/s. The equipment of the key stations of the municipal backbone network is configured in a double way to realize the full co-verage of 66 kV 220 kV substations.

2006年IBM 首次提出智能电网的概念.经过

十年的快速发展，目前我国已建设完成“五交八直” 特高压工程.初步形成以特高压为骨干网、各电压等

级协调发展的统一、坚强的智能电网网络架构'。

近年来美国、加拿大、乌克兰等国大面积停电事故对 超大型电网的可靠性和安全性提出了挑战。骨干传 输网作为智能电网强大的支撑网络.为智能电网数

据的传输提供了高速、双向、实时的智能通道，是超

大型电网向智能电网演进的重要组成部分：.因此

有必要建设安全可靠、层次分明、容量充足的骨干传 输网。
