A Web-Based Power System Modeling System Design And Its Implementation

Graphical power system analysis software is the combination of different technology, such as graphics technology, Internet technology. They have been widely used in power system program, running mode analysis, security and stability analysis, contingency analysis, remote control, etc. Most of them are platform-based or Client/Server-based; there are many problems in copyright protection, system update, maintenance and data exchange, etc. With the development of power market reformation, people propose high request on information exchange, fast upgrading of software system. The old modes have already been unable to meet the new demand, so web-based graphical analyze system which is developed with IT technology and graphics technology can solve some problems among them effectively, and also has great and practical value.In this paper, Java and MATLAB have been combined to develop a web-based graphical power system modeling and analyze system. The graphical and interactive user interface programmed with Java can draw equipment model easily, and it can generate the data file then upload itautomatically. The GUI is platform-cross. The system use MATLAB Web Server as computational engine ,which can compute on server and send result to user. The architecture of the system, the pivotal technology used in this system and the implement method are detailed described in this paper. Finally, we demonstrate all the function of the system with IEEE-30 bus system.
