虚拟现实开发平台在变电站仿真系统中的应用

Application of Virtools in Substation Simulator

为应用虚拟现实技术于变电站仿真系统,对系统中的电气设备抽象概括出了"物理特性+电气特性+行为特性"的分析方法,并用"输入—控制—输出"模型描述电气特性和行为特性。借助3DMAX和Virtools工具构造出的虚拟电气设备不仅更加接近真实设备,而且具有很高的可维护性。同时,把常用的虚拟电气设备设计成拖拉对象,用户可方便地修改虚拟变电站中的某些场景,使变电站仿真系统具有更大的可扩展性。

Now, virtual reality is applied to the study of substation simulator little by little, uniting the excellence of software simulator and physical simulator. In this paper, 3DMAX is used to setup the scence model, the interior landscape model, and the electrical device model standard. The material system and the picture system of 3DMAX make the three dimensional model looks more real. Electrical devices in substation simulator are abstracted and the analysis method which is based on physical characteristic, electrical characteristic and behavioral characteristic is generalized in this paper. Electrical and behavioral characteristic is also described by the model of Input Control Output. Virtual device, which is constructed by 3DMAX and Virtools, not only comes close to the real device but also has high maintainability. At the same time, designing the typicai virtual device to be the drawing object enables us ers to modify the certain scenes of virtual substation expediently and substation simulator to have larger extensibility.
