| 摘要: |
| 由于智能变电站内二次回路需要模拟的对象较多，并且具有时序性特征与非时序性特征，导致智能变电站二次回路三维可视化效果较差。基于此设计了一个基于电网信息模型(grid information model, GIM)模型的智能变电站二次回路三维可视化系统。系统硬件部分，重点设计处理器、互感器采样模块与互感器采样模块；系统软件部分，对空间数据组织与管理、几何元素间求交计算、模型切割、模型贴合。在此基础上采用GIM模型建立时序模型，完成智能变电站二次回路三维可视化系统的设计。实验结果表明，所提基于GIM模型的智能变电站二次回路三维可视化系统不仅提高了建模帧速、可视化效率与可视化效果，所设计系统的可视化结果基本不存在缺陷。所设计系统还减少了施工变更次数、施工成本与施工周期，施工成本最大降幅接近0.5倍。因此，说明所设计系统提高了变电站二次回路三维可视化效果，可以满足系统设计需求。 |

| Abstract: |
| There are many objects to be simulated in the secondary circuit of a smart substation, and it has the characteristics of timing and non timing. This leads to the poor three-dimensional visualization. A three-dimensional visualization system of the secondary circuit of a smart substation based on a GIM model is designed. The hardware part of the system focuses on the design of processor, transformer sampling module and transformer sampling module. In the system software part, the spatial data organization and management, intersection calculation between geometric elements, model cutting and fitting are carried out. The timing model is established using the GIM model to complete the design. The experimental results show that the proposed system not only improves the modeling frame rate, visualization efficiency and effect, but also has no defects in the visualization results. It also reduces the number of construction changes, cost and period, and the maximum reduction of the construction cost is close to 0.5. Therefore it shows that the designed system improves the three-dimensional visualization and can meet the requirements of system design.
