摘　　要：文章对目前电力系统省级SDH光传输集中网管现状及问题进行分析,结合国家电网有限公司"两层三区"架构等建设最新要求,提出一种核心层和接入层改造方案,方案通过服务器双网卡、交换机堆叠、数据双上联通道、多MPLS-VPN等设置,在数据隔离和抗单点失效方面取得良好效果。方案已在安徽SDH光传输集中网管改造中应用,且运行安全、稳定并具有较高的交互效率。Considering the latest requirements of the "two-tier and three-zone" architecture of State Grid Corporation of China,this paper analyzes the current status and problems of provincial SDH optical transmission centralized network management of power systems,and proposes a core layer and access layer transformation scheme.The scheme has obtained good results in data isolation and anti-single point effectiveness through settings of server dual network interface controller,switch stacking,double uplink data channel,multiple MPLS-VPN and so on.The scheme has been applied in the SDH optical transformation of centralized network management in Anhui,and it is safe,stable and has high interaction efficiency.
