Construction And Implementation Of Power Information Network

With the advancement of information technology of power system, power systems have become increasingly demanding information network, the power industry was diversified hosted business systems and high-information, dramatically increased traffic flow requires a high bandwidth and high transmission rate network support.In order to meet the information technology development, promotion of information service system of promotion, Zhaoqing Gaoyao Power Supply Bureau conducted a comprehensive information network renovation project, We abandoned the original old hubs, used switches with routing function to build a high-speed network. This network covers power substation,Business hall.And we construction a new network of Gaoyao Power Supply Bureau, interconnection with Zhaoqing Bureau.This article analyzes the current status network of power system, point out the defects of the old network, then according to the actual needs of users, based on business traffic analysis and network security analysis, with current web technologies and trends, we select the appropriate network technology, propose to build a power information networks, and the specific implementation process.This article focuses on the networking power principle of integrated data network, design basis, the construction program, basic configuration and their implementation. We use MPLS VPN + VLAN technology to build the network, the floor switches use optical fiber directly connect the floor switches, and the link bandwidth was extended to 1G, access layer switches with VLAN transparent transmission layer; and also designed VPN network to distinguish different business segment, ensure the safety and independence of the information systems; application routing switc, QoS guarantee to provide comprehensive services; at the same time, all network equipments access to the management system, this network management system using real-time monitoring network equipment status, to detect equipment failures, improve the operation and maintenance capabilities and network management ability to make the network safe and reliable.
