输电网线路规划的可视化实验

Visualization Experimental Approaches for Power Grid Planning

在输电网线路规划中,如何使得线路长度最短是工程设计人员必须考虑的一个重要因素。文章介绍了作者研制的一种最短路径可视化实验装置的工作原理及其应用情况。该装置基于表面活性剂溶液的普拉图几何规则和最小Steiner树理论,能够通过可视化实验方法找出连通若干地点的输电网规划线路的整体最短长度。对东北电网的实验证明该装置能得到理论上较为理想的结果,尤其对于某些节点分布呈正多边形的局部线路,优化效果较明显。

In power transmission line planning how to make the length of transmission line the shortest is an important factor that the designer should consider. In this paper the working principle and application of a visualization experimental device for the Shortest path of transmission line are presented. Based on the Plateau geometry general rule of surfactant solution and the theory of Steiner minimum tree, the presented device can find out the entire shortest transmission length of power network to be planned which connects several locales by visualization experiments. The experimental results of Northeast China Power Grid prove that using the presented device a more theoretical ideal planning result can be achieved, especially for some local lines whose nodes are distributed in regular polygon the optimized effect is more evident.
