摘　　要：在电力行业,目前电厂对电力管道服役状态的监督管理仍然停留在由人工完成的“静态”阶段,存在掌控信息不全面和不及时的问题,无法满足安全生产的需要.传统的数字化软件操作繁琐、功能不足,且缺乏对管道运维信息的关注.针对以上问题,本文提出了数字孪生五维模型的三维电力管道系统设计.首先,采用草图造型和参数化方法进行管道系统的三维重建,快速实现虚拟实体的构建,直观展示系统的真实场景;然后,采用智能的管理技术,获取和维护管道的运行信息,评估与预测管道的安全状态,实现物理与虚拟信息的融合;最后,基于系统的应用框架进行系统设计,并实现了界面简洁和功能实用的系统原型.目前该系统已经在电厂试运行,初步结果显示该系统对电厂的运维和安全化管理起到了较好的效果.At present, in the electric power industry, the power plant’s supervision and management of the service state of power pipelines remains at the static stage, by manual work. On one hand, information control is incomplete and untimely, which does not meet the requirement of security production. On the other hand, the traditional digital software has cumbersome operation, lack of function and attention to maintenance information. In view of the above problems, a3D power pipeline system design based on a digital twin five-dimensional model is proposed. Firstly, a sketch modeling and parametric designing method is used for 3D pipeline reconstruction to quickly realize the construction of a virtual entity and intuitively display the real scene of the system. Then, a smart management technology is utilized to monitor the operation data, predict the security state of pipelines, and integrate physical and virtual information. Finally, a prototype with a concise interface and practical functions is implemented. After being used in actual electric factories, this system initially shows improvement in the efficiency of service and security management of power pipelines.
