摘　　要：针对现有变电站仿真培训系统现场感缺乏和用户体验不足的缺点,提出一种沉浸式变电站仿真培训系统方案,将三维虚拟现实引擎技术、多通道视频输出技术、虚拟人驱动技术、Kinect体感交互和漫游技术引入变电站仿真培训系统,从视觉、听觉和交互方式上为变电站运行人员构建了沉浸式变电站虚拟实境。其中,多通道视频输出技术采用了通过转换计算机底层图形数据的创新方法实现;基于Kinect体感交互的虚拟人驱动技术主要针对Microsoft Kinect SDK的骨骼追踪系统无法识别人物手势动作的缺点,创新使用动态时间规整(dynamic time warping,DTW)算法弥补其不足;基于Kinect体态识别的场景漫游技术实现了虚拟人物在仿真场景中的漫游和转向控制。实际应用效果表明,该系统增强了用户体验,提高了用户使用培训系统的兴趣,可有效提升培训质量,具有很强的实用性。在研究中还对Kinect识别范围和动作识别率进行反复测试,积累了大量实验数据,为后来的研究者如何避免仿真系统设计误区提供了参考。Aimed at the disadvantages of existing Substation Operator Training Systems（SOTS）, this paper presents a system design of immersive SOTS, and has developed the core technologies, such as 3D virtual reality engine technology, multi-channel video output technology, virtual human drive technology, Kinect somatosensory interaction and walkthrough technology, etc. Immersive SOTS provides immersive substation virtual reality environment in the respects of auditory and visual senses and interactive mode for substation operators. Among them, the multi-channel video output technology is achieved with innovative methods to convert the underlying computer graphics data. The virtual human driven interactive technology uses dynamic time warping（DTW） algorithm, making up for the disadvantages in Microsoft Kinect skeletal tracking SDK system which cannot recognize people gesture. With the scene roaming technology based on somatosensory interaction, the effect of controlling virtual character roaming and steering in simulation scene is achieved. This system enhances user＇s experience and increases user＇s training interest, effectively improving the quality of training with strong practicality. In the study, repeated testing was performed to identify the scope and Kinect motion recognition rate, and a large number of experimental data were accumulated for later researchers＇ reference that how to avoid simulation system design errors.
