With the development of modern electric power enterprises and geographic information system technology continues to improve, the integration of a graphical editor, data management, geographic queries, network analysis, equipment management, maintenance management and the full range of management functions such as distribution SCADA system, as a modern integration of information systems into the electricity system, to provide users with a complete management system has a monitoring function, and will provide users with the convenient grid graphics and data entry, management, query, analysis and rich decision support functions will greatly improve the management level and service quality of the electric power industry as a whole, has brought great economic benefits. Set with grid management information systems and distribution SCADA systems in an integrated system, giving new vitality of geographic information systems will be upgraded to an online system, not only can reflect the basic data graphics, can also be real-time reflection network of information. This paper studies the status quo of the current distribution network operation and management, difficult to unify data exist for domestic distribution network management information systems and maintenance, long development cycles and other problems, design and set of effective GIS-based graphics editing system. The integrated design allows the user to maintain a data makes the data can be fully shared, so that both can fully guarantee the consistency of the data, but also greatly reduce user workload, having to repeat data entry. The integration of the design principle is not only the distribution of design integration in the underlying data, as well as functional integration and interface integration. Distribution Management System and Distribution SCADA system is fully integrated, fully meet the functional requirements of the entire system. The graphics editing system by studying the common international geographic information data storage, compared the advantages and disadvantages of the various storage to determine and achieve the Shape file format to save the graphics data, graphics editing system with good versatility , ease the geographic background picture and other users access to the data, but also to ensure that the screen display of the graphics data to good effect. In this paper, through the study of graph theory, mathematical methods and advanced object-oriented technology, design and mathematical model oriented distribution network equipment, this design approach, the most important feature of a topological relations. At the same time to achieve the model based on various features of the editing system. Convenient thematic map conversion tool is designed and implemented to facilitate the use of all types of users, such as the main wiring diagram conversion ring map conversion, extraction stations Figure extracted feeder diagram, and finally to the geography along the layout and monitoring harmonization of all thematic maps with data, topological relationships, provide data for advanced analysis function of the distribution network. The integrated graphics editing system to study the problem of the current user in the course of drawing, done in the design and implementation process drawing steps and drawing process is simple, easy to operate, user-friendly and maintenance. The end of the paper, through a practical example, to verify the usefulness of this graphics editing software a reasonable and engineering design.
