电力传输系统的可视化以单线图为中心，单线图是电路连接和元件的简化逻辑描述。这样的图形绘制对于支持电力系统数据的研究、分析和表示是有用的。本文提出了一种自动化的方法来生成单线图，给定变电站标识符与地理标签和系统总线分支模型。给出了两种绘制变电站的方法：力导向方法和贪婪方法，它们以不同的方式修改所绘制的变电站的位置和大小。对于变电站间的输电线路布线，采用了基于Delaunay的方法，该方法将输电线路图分段，以避免与变电站和其他线路重叠。这些方法在间距、地理背景、相对直线和计算速度方面表现出良好的视觉特性。其结果是，大型电力系统，真实的和合成，可以很容易地和快速地可视化与图，合并地理环境与逻辑清晰。
Visualization of electric power transmission systems centers on the one-line diagram, which is a simplified logical depiction of the circuit's connections and elements. Such a graph drawing is useful for supporting the study, analysis, and presentation of power system data. This paper proposes an automated way to generate one-line diagrams, given substation identifiers with geographic tags and the system bus-branch model. Two approaches to drawing the substations are given: a force-directed approach and a greedy approach, which in different ways modify the position and size of substations as drawn. For transmission line routing between substations, a Delaunay-based method is employed, which segments the transmission line drawings to avoid overlapping with substations and other lines. These methods show good visual properties in spacing, geographic context, relatively straight lines, and computational speed. The result is that large power systems, real and synthetic, can be easily and quickly visualized with a diagram that merges geographic context with logical clarity.
