三维设计技术在变电站电缆敷设中的应用研究

Research on application of 3D design technology in cable laying of substation

为了实现电网建设及运营的数字化,加强对其全生命周期的管理,以电缆敷设的三维设计为基础,采用三维建模软件建筑信息模型(BIM)为技术支撑,重点分析了电缆敷设过程中桥架和电缆的三维建模方法,利用软件的可视化功能对电缆施工进行了模拟分析,并利用蚁群算法原理计算了电缆敷设过程中的最短路径。最后以国网浙江公司某750 kV变电站建设为例,对三维设计展开了应用试验分析,应用结果表明该设计软件达到了预期效果。

In order to realize the digitization of power grid construction and operation and strengthen the management of its whole life cycle,based on the three-dimensional design of cable laying and supported by the three-dimensional modeling software BIM,the three-dimensional modeling method of bridge and cable in the process of cable laying is emphatically analyzed,and the cable construction is simulated and analyzed by using the visualization function of the software,The shortest path in the process of cable laying is calculated by using the principle of ant colony algorithm.Finally,taking the construction of a 750 kV substation of State Grid Zhejiang company as an example,the application test analysis of the three-dimensional design is carried out.The application results show that the design software has achieved the expected effect.
