Power System Visualization Research Based On Svgtechnology And Cim Model

Accompanying the development of power system, dispatching centre now faces more and more problems. As the most important part, EMS (Energy Management System) must be constructed under the requirement of modern power systems. More efficiency, flexibility and openness are needed. Now, system operators have to deal with even more large number of data when they monitor and operate a power system. New techniques are even more needed to help them improve their efficiency.Visualization technique can provide operators some vivid diagrams, curves or tables so as to help them to gather the most critical information to power system operation. Also power system operators can get a high efficiency and can avoid some mistakes in the daily operation with the help of good visualization techniques.The newest SCADA/EMS system has applied some advanced technologies, such as opening and distributed structure designing, network embedding, objective orient database, middleware, WEB. The EMS system is also designed based on some international standards, such as IEC-61970, CIM, SVG, etc. SVG means scalable vector graphics. It is an international standard for graphical exchange in different EMS systems.In this thesis, techniques of CIM and SVG are used to develop the system of"Power System Online Security Assessment and Visualization"applied to Tianjin Electric Power Company. Some key visualization functions of the system are designed and completed, such as, parsing and importing of SVG files into the system, plotting of the substation and line diagrams combined with CIM and real-time measurement data. All the functions have been successfully integrated into the system, and now are applying in the online environment.
