A Study On Short Circuit Computation Of Power System Based On Browser/Server Mode

The application of computer technologies promotes the development of power industry system greatly, and has been one of the most active research fields for power system. Along with the development of computer technologies, a new-style software framework—B/S (Browser/Server) mode appears, which is easy to update and maintain. The application of B/S mode in power system is a hotspot recently. It is valuable to make the full use of B/S-based graphical short circuit computing software in power system.The .NET components with function of drawing are developed by using MS-Visual C# and GDI+(Graphical Device Interface Plus). These components can draw many kinds of electric component models, such as buses, transformers and lines. The models and parameters of components can be edited or reset. The users can draw power system pictures on IE expediently and fastly when the component is embedded into Web page. This paper presents the function analysis,design and program implementation of the component in detail.Beside of developing the .NET component, the paper also studys the break in turn in short circuit computing. Now the main solution for the break in turn is compensation method. However, it can't solve the situations when the numbers of circuits broken in system is more than or equal to three. In order to calculate the break in turn in this situation, low-rank update method is proposed. The paper detailly describes the background, the arithmetic conditions and the implementation of this method.In the end, the paper takes the example of 5-buses and N1047-bus system to...
