| May 2009, the State Grid Corporation proposed the strategic development objective of constructing a strong and smart grid. The distribution system is one important part of smart grid. The objective proposed gives the distribution automation a new content and indicates the direction for the development of distribution automation.Because of each city's differences in economic development and distribution network construction, State Grid Corporation proposed "the technological principle for building and alteration of distribution automation in the pilot regions". The principle requests that the regional economic development, the load difference, the reliability requirements, the status of distribution network and communications, and the relevant conditions of application systems should be analyzed; the features and configuration requirements of distribution equipment, communication means, master stations, sub-stations and terminal units should be planed and designed legitimately; a phased implementation plan of distribution automation should be proposed.In this paper, the status of distribution network in Jinan is analyzed carefully, the pilot construction area of distribution automation is selected and the building program of distribution automation of Jinan is proposed. The building program involves the alteration of grid structure, the construction of main station, feeder automation, devices and terminals, distribution communications network, information exchange bus, interactive information applications, distribution network management etc.By the construction of smart distribution network in Jinan Power Supply Company, a "strong, reliable, smart, green " electricity supply network will be created. The network has the features of "self-healing, compatible, interactive, optimization" and covers the entire city distinct of Jinan.Through the self-healing control, the distributed power access control, the interaction between information systems, the interaction with users, and the optimal operation of the economy, the supply reliability and fast restoration capability of distribution network will be improved, the operation and management level will be heighten, the fault time of distribution network will be effectively reduced, the customer satisfaction will be enhanced, the achieve operational excellence in the distribution network will be realized as result. The implementation of this project has important direction significance for the promotion of distribution automation in the Shandong Province. |
