The Study Of Graphic Modeling Of Distribution Network Based On Object Oriented And Database Technology

While conducting the kinds of calculating and simulating work of the distribution network , in order to decrease the pressure of technicians majoring in inputting,altering and maintaining large amount of data and avoid human mistakes unnecessary as much as possible , this article describes the power system network structure by the way of graph which is the most concise language in project. As the computer graphics develops fast and the dominance of object-oriented programming establishes, computer graphic modelling becomes the best method in electric graphic modelling without any doubt. The article models for every component constituting the distribution network by object-oriented programming in computer based on .NET platform, and packages them into classes which could be called by the drawing and simulating system by Visual C#, then it will be at a glance while inputting the data and outputting the results on the basis of these completed electric power graphs.The widely application of visual programming technology and object-oriented technology in the graphic systems bring us a new idea of how to develop huge graphic system. We can describe the real power system by the Object-oriented graphic modeling method. We also can develop a standard graphic user interface with easy operation and good interface by Visual C#, a leading visibility programming technology of Windows. This article presents a integrity and general graphic modeling approach, which including exploiting electrical graphic components using C#, the function of graphics display and manipulation, finishing incorporation design between graphics and data base and so on. A graphic database integration system of distribution network has been implemented based the method of graphic modeling above mentioned, which using Visual C#, based on Windows .NET Framework, adopting the technology of multi-thread and dynamic memory distribution.
