摘　　要：在常规Voronoi图应用研究的基础上,提出了基于顶点加权Voronoi图实现变电站最佳供电区域自动划分的计算几何方法;在整个供电区域负荷密度相同的条件下,考虑变电站的主变压器容量大小对其周围供电区域的影响能力的不同,提出基于变电站主变压器容量确定权重、划分变电站供电区域的新思路,确定了顶点加权Voronoi图的构造方法.算例表明该方法直观、快速、有效,最佳供电区域划分结果具有一定的有效性和合理性.Based on the application research of Voronoi diagrams, a new computing geometry approach of the power best supply area automatism plotting is given using apex weighted Voronoi diagrams. At the same load density of the whole supply area, the difference capable of the affection on power supply area size of different main transformer capacity must be considered between different substation. New methods of the weight＇ s definition founded on the capacity of the substation main transformer and best power supply area plotting were put forward. A structural method of apex weighted Voronoi diagrams has been established. The results demonstrate that this method is visual,speedy and effective, and the result of the besi supply area plotting has constant validity and rationality.
