摘　　要：线路走廊或空间障碍因素的限制,使电源与负荷点之间的电气距离与其欧氏距离存在差异。应用障碍V图实现变电站供电区域的划分,可以在变电站位置及障碍因素已知的情况下,在满足相关技术约束的条件下,以电气距离之和最短为目标函数,利用障碍V图的几何特性,实现变电站供电区域的最佳划分。算例表明,该方法具有一定的有效性和合理性,能够满足负荷点到其供电电源的电气距离最短的要求。From substations to loads, there are some differences between the electric distances and Euclid distances because of the limits caused by line corridors or space obstacle factors. This paper presents a novel method for dividing the substations＇service areas based on the obstacle Voronoi diagram. Given the existing substations＇ locations and the obstacles＇ factors, this method takes advantages of the obstacle Voronoi diagram＇s geometric characteristics and imports the minimum of the electric distances＇ summation as the target function with the technical restrains concerned. Finally the method realizes the optimal division of transformer substations＇ service areas. Actual examples demonstrate the validity and rationality of the proposed method.
