| With the continuous development of China's economy and society, the relationship between power grid and geographic information is more closer. The traditional power grid computer system is unable to meet the requirements of grid development. Power Grid GIS is a comprehensive system engineering which integrated power systems technology and geographic information systems(GIS) technology and also computer science. This paper research Power Grid GIS software development, in the traditional grid defect management, while establishing grid geographic data model, to achieve the spatial data and attribute data centralized management of the power of geographic information systems.The main work of this paper are: power system reliability for real-time high, the grid structure is complex, and the amount of data characteristics, the power of GIS network model for in-depth research. GIS analysis and comparison of the development of the implementation, development tools, and several common database model, and based on the analysis results to Visual Graph as a GIS platform, SQL Server 2000 as a spatial database platform, using Visual C ++ 6.0 program was designed and implemented Power of GIS architecture. After testing, the system can realize the power of GIS basic graphics capabilities, as well as some advanced applications.Methods and software systems described herein generally speaking, can meet the design requirements, but from a perfect power GIS system architecture there is a certain distance, there are still a lot of work to do for further Application. |
