| With the high informationization and automation of the power system, the scale of the network becomes more and more large. The power company need manage large numbers of data of the system equipments. And the power equipments demonstrate the complexity on the space for the transmitting characteristics. Today, GIS has already been applied in many fields of the power system. For example, in power transmission and transformation management, in power distribution management, in power consuming management, etc. With the gradual popularization of the network technology, by setting up integrated solution in enterprises, resource sharing and information synchronization are primary problems when we establishing systems. In this paper, by using MapX and MFC developing tools, a research to GIS system for the power distribution network is carry on. And, a presentation on the development process of the geographical information system is also brought out. The following are the main jobs of this paper. (1) The database of the power distribution network has been designed, and the information of each instance and the whole network has been integrated. The corresponding component property of the GIS graphic database and property database has been transformed by using various kinds of results. The GIS application system is different from the general systems. A large amount of basic data should be inputted when establishing the system, and some new data will be built based on these data when system running. Another characteristic of the GIS application system is that there is a large amount of graphic data in the system. The system data organization is different from the pure property data organization according to the characteristic of the graphic data. As a result, different database design methods are adopted. The space data and non-space data have been placed into different type database. (2) The development technology for GIS has been studied in detail. The software of the system has been developed with the powerful MFC class library and MapX controls and it will be help for the future research. System security modules, map operation modules and data management modules are included in this software. Some other functions including user logging in, user management, map editing, map zooming, map moving, eagle eye moving, distance ranging and corresponding properties information of the power distribution network searching. By assembled with these functions, a complete GIS system for the power distribution network has been achieved.
