摘　　要：针对原有系统无法真实展示工程地理环境的问题,研究基于数字孪生的输变电线路三维数字化系统的设计方法。在硬件设计中,布局输变电线路网络架构,嵌入OPC-UA服务器,绑定传感器节点位置。在软件设计中,建立输变电线路空间数据库,构建数字孪生三维虚拟模型,完成三维数字化系统的设计。以复杂地区输变电线路建设工程为对象进行实验,实验结果表明:选择多个场景中的位置线段进行距离测量时,两组传统方法对实际距离测量存在误差,生成的地形图像发生形变,而本文系统可完全还原输变电线段距离,具有实际应用效果。Aiming at the problem that the original system can not truly display the engineering geographical environment,the design method of three-dimensional digital system of transmission and transformation lines based on digital twins is studied.In the hardware de-sign,the power transmission and transformation line network architecture is laid out,the OPC-UA server is embedded,and the sensor node location is bound.In the software design,the spatial database of power transmission and transformation lines is estab-lished,the digital twin three-dimensional virtual model is constructed,and the design of three-dimensional digital system is com-pleted.Taking the construction project of power transmission and transformation lines in complex areas as the object of the experi-ment,the experimental results show that when selecting the location line segments in multiple scenes for distance measurement,the two groups of traditional methods have errors in the actual distance measurement,and the generated terrain image is de-formed.However,the system in this paper can completely restore the distance of power transmission and transformation line seg-ments,which has practical application effect.
