Network management system design for a large rural electric power bureau

The Liu Chou Power Supply Bureau is a publicly owned rural electric distribution organization providing retail electric service to over 200,000 residential, irrigation and industrial customers in Southern China. A state-of-the-art load management information system, using the latest network technology, such as fast Ethernet and VLAN, is used to replace the old ones. This system not only retains compatibility with the original system, but also provides other specialties such as easy centralized management, performance optimization, system configuration, counting management, error recovery and security management. This paper describes the rural electrical bureau network architecture design, its information flow among the 150 nodes, 16 remote stations, network performance, configuration and counting management, with rich examples of SCADA.
