【摘要】 电力系统的正常运行是人类安全生产生活的重要保证。利用科学计算可视化将获取的大量电力系统数据及时转化成对运行调度人员进行决策的有用信息,对电力系统安全保障具有重大意义。网络化科学计算可视化,作为可视化技术和网络技术相结合的产物,可以共享科学计算结果、提高可视化渲染速度,同时便于软件升级及维护。本文设计实现的网络化的电力系统实用动态安全域可视化系统就是其应用的一个典型例子。网络化的实用动态安全域可视化系统的主要功能是为用户展现实用动态安全域(PDSR),运行点以及运行点与PDSR边界的距离关系,为调度人员决策提供依据。本文通过分析和比较OpenGL, VRML, X3D, Java3D等网络化科学计算可视化主要方法后,结合系统的实际需求,采用C/S开发模式,OpenGL技术进行开发的。客户端是在Windows系统下开发完成的,主要实现绘制三维场景、与用户进行交互以及显示动画等功能。服务器端是在Solaris系统下开发,主要实现数据处理、线程管理、数据管理等功能。本文采用了关键帧技术实现动画显示,并将P2P技术应用于关键帧的产生。在本系统设计实现后,用户在客户端成功连接服务器后可以准确、快速地观察到三维场景,并可通过旋转、缩放等交互方式多角度观察三维场景。此外,系统的动画生成速度快,并且显示流畅。总之,本系统为运行调度人员的决策提供了良好的信息基础。更多还原

【Abstract】 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.更多还原
