The Information Management System Of Power Marketing District Research

The power supply company administers customers and partitions different power marketing districts according to the supply transformers, the pattern has the characteristics that making current supply and consumers' property clear, so the pattern is the furthest excellent pattern of the electric power market at present. But the instance relating to power marketing district is very complicated and its information manages level is low at present. Therefore, it is very impendence that researching the information management system of power marketing district for improving information management level of power marketing district.Geographic Information System (GIS) has already been applied to each aspects of electric system broadly, because power marketing districts have large amount of geographical feature data and attribute data, which adapting to GIS exploitation very much. Therefore, this paper researches the information management system of power marketing district base on GIS, primary contents as follows:(1) Exploitation fashion,technique,software and hardware equipments of the system are analyzed.Exploitation fashion and exploitation technique are analyzed, the OO techniques are adopted, the integration-twain-exploitation fashion which combine the GIS implement software and visualization implement Visual Basic is used, the information management system of power marketing district are explored. The makeup of system hardware equipments is introduced.(2) Detailed demand analyses and system designs are processed.Detailed demand analyses and operation investigations are processed. The system design projects are given according to demand analyses. The functions, structures, codes, map layers and databases design of the information management system of power marketing district are processed.(3) The system main functions and applications are analyzedThe system main functions are analyzed, the produces which the spatial data and the attribute data bind, the custom tool based, spatial inquiry and spatial analysis and production topic chart realization process are given and applications effect of system function and collectivity are analyzed.(4) The most short route arithmetic of the information management system of power marketing district is application researched.The most short route Dijkstra arithmetic is researched and ameliorated, for example, how to choose the furthest excellent fit situation of the transformer in the locale reference design function, the application of the amelioration Dijkstra arithmetic is given in the paper.
