Study & Implementation Of Integration Of Graph And Database For Power System Graph Platform

Graphical user interface is a very important part of SCADA system, and integration of graph and database is a trend of graphical technology. The thesis makes some applied research in this area. With three modules of graph platform, user defined graphic elements and user defined attribute we can finish the integration. And we can change the graphic elements and database efficiently without changing the program, and it can make the graph system openly and agile much more.The thesis first analyzes the design method used in the graph system ,some important design methods are proposed from the perspective of software development in detail, and some solutions and data flow diagrams are proposed too. Subsequently the thesis introduce the method of design the two modules of user defined graphic elements and user defined attribute in detail. Finally, the author gives a frame of calculating theory line loss on the graph system. This can prove the graph system is openly and extendable.
