Networked Visualization System For Practical Dynamic Security Region

The security of electric power system is very important for human beings'life. Visualization which can transform a great deal of electric power data to useful information in time for decision-making can be used in security alarm and control. Networked visualization, as the conjunct of visualization and network technology, can share the latest scientific fruit, speedup rendering and be convenient for upgrading of software. Networked visualization for Practical Dynamic Security Region which the paper designed and implemented is a typical example of it.Networked visualization for Practical Dynamic Security Region (PDSR) shows PDSR, running point and distance relation between running point and boundary of PDSR for users to make decisions. After comparing some methods of implementing networked visualization such as OpenGL, VRML, X3D and combining practical requirement, this project is deployed with OpenGL using C/S (Client/Server) design. The client implements rending, interaction with users and displaying cartoon in Windows. The server implements computing, thread management, data management and so on in Solaris. The paper uses key-frame technology to implement cartoon and applies P2P technology to producing key-frame.After the design was implemented, users can observe three-dimension scene quickly when they connect the server successfully, and observe it from multi-view points through zooming and rotating. In addition, cartoon can be created quickly and be displayed smoothly. In a word, the project provides useful information for decision-making.
