水轮发电机组虚拟检修平台设计与应用

Design and Application of the Virtual Maintenance Platform for Hydro-generator Units

传统水轮发电机组检修培训方法存在效率低、周期长、现场教学具有一定危险性等问题,培训效果难以保证,为此提出一种基于虚拟现实的水轮发电机组检修拆装三维可视化培训方法和检修培训平台。该方法以三峡水电站混流式机组为仿真对象,运用3dsMax创建元件级三维检修模型,基于Unity3D搭建三维可视化检修拆装交互场景,设计实现了检修流程知识三维可视化展示、检修拆装过程交互式实操、检修技能考核在线评分等功能,并基于AHP-模糊综合评价法与检修元件物理空间约束解决了非确定性检修步骤准确度评价难题,构建水轮发电机组检修培训自主学习的完整闭环。实际应用表明,该平台满足了水轮发电机组检修培训需求,为水轮发电机组大规模标准化检修提供有效技术支撑。

The traditional hydro-generator unit maintenance training method has problems such as low efficiency,long period,and certain dangers in field teaching,and its training effect is difficult to guarantee.Therefore,a virtual reality-based three-dimensional visual training method and training platform for the maintenance,disassembly,and assembly of hydro-generator units are proposed.This method takes the Francis turbine-generator unit of the Three Gorges Hydropower Station as the simulation object,uses 3dsMax to create the component-level three-dimensional maintenance model,and constructs the interactive scene of three-dimensional visual maintenance,disassembly,and assembly based on Unity3D.It designs and implements the functions of a three-dimensional visual display of maintenance process knowledge,the interactive practical operation of maintenance,disassembly and assembly,and online scoring of maintenance skill assessment.It solves the problem of accuracy evaluation of uncertain maintenance steps through the AHP-fuzzy comprehensive evaluation method and physical space constraints of maintenance components and constructs a complete closed-loop of independent learning for the maintenance training of hydro-generator units.The practical application shows that the platform satisfies the requirements of maintenance training of hydro-generator units and provides effective technical support for large-scale standardized maintenance of hydro-generator units.
