摘要: 以浮动核电站换料作业为研究对象，提出数字孪生技术应用到浮动核电站的技术路线，整合设计数据并开发核燃料装卸舱的数字孪生系统，建立虚拟舱室模型并开发新燃料运输过程控制程序，采用基于过程控制中的对象链接与嵌入技术统一架构（OPC UA）的通讯协议实现虚拟舱室模型和控制系统的双向交互。结果表明，开发的数字孪生系统能够为换料作业操作设计过程的人员站位、操作流程设计优化提供依据。因此，本文提出的数字孪生技术应用方法能够服务于浮动核电站的设计阶段，并为其在浮动核电站全生命周期的应用提供参考。Abstract: The research object is the reloading operation process of a floating nuclear power plant. A technical route of digital twin technology is proposed for application in floating nuclear power plants. Design data is integrated and used to develop a digital twin system for nuclear fuel handling cabins. The virtual cabin model is established, and the new fuel transportation process control program is developed. Based on the OPC Unified Architecture (OPC UA) communication protocol, the two-way interaction between the virtual cabin model and the control system is realized. The results show that the digital twin system can provide a reference for the determination of personnel positions and the optimization of the reloading operation control process. Therefore, digital twin technology can serve the design phase of floating nuclear power plants, and can provide a reference for the application of digital twin technology in the full life cycle of floating nuclear power plants.
