Abstract


Scientific visualization is the late 1980s as a technology for the development of computer science, this technology is very suitable for processing and display large amounts of data, and therefore has been widely used in all areas of data center. Power system visualization technology is a large number of power system data into a computer image, the dispatcher can quickly and accurately obtain the information passed. This technology can take full advantage of the graphical perception of the people, which intuitively reveals a deep state data associated grid operation, thereby enhancing the efficiency of the system operating personnel, to ensure the safe operation of the power grid. Intelligent grid scheduling system grid model and graphical data structure custom visualization technology has a wide range of applications, it is difficult to reuse, interactive cost is also very high. Power system visualization goal of further development of standardization and openness. The IEC61970 standard proposed by the International Electrotechnical Commission (IEC) has become the international standards adopted in the electricity enterprise systems application integration. The standard explicitly proposed CIM model as a grid model of information exchange standards and recommended SVG as the graphics interchange standard. Plain text graphics format SVG is an XML-based standard, the powerful, it is suitable to describe the power network model. Therefore, the study SVG-based power system visualization technology is a critical direction. The purpose of this project is to build an entirely new platform support SVG visualization to improve software reusability and development efficiency, reduce maintenance costs. Most of the existing SVG browser Internet browser-based applications, it is difficult to go through the extension applied to other systems. With the development of computer hardware and software technology, 3D visualization techniques have become increasingly important. Display SVG file to support 3D platform, SVG rendering engine must be developed under a 3D environment. After a comprehensive study SVG standard, designed and realized SVG rendering engine, its implementation process including the SVG parsing and rendering of two parts: the SVG analytical framework is based on the TinyXML realized, TinyXML is a simple and compact, using C language XML parser, the parser can be easily integrated into applications; SVG rendering framework is implemented using OpenGL (Open Graphics Library), it is a cross-language, cross-platform programming interface used to generate two-dimensional , three-dimensional computer graphics. The power system of the engine to meet the SVG format graphics information basic display needs, also offers an interactive interface for the visualization of functional requirements. Finally, the paper briefly describes the CIM / XML / SVG intelligent scheduling system, and SVG specific application in which elaborate. In this paper, SVG visualization of the power system in a viable and effective use of the program, but the program still needs further research and development. It needs to be noted that this is not the only solution. The final chapter of the full text summarizes and gives future outlook, also proposed a possible research directions a SVG applications in the power system visualization, the study of a Web-based visualization platform , based on the rise of the Internet platform 3D technology (such as WebGL) makes it possible.
