在研究常规Voronoi图应用的基础上,针对配电网负荷分布不均匀的情况,提出了基于自适应权重Voronoi图的配电网供电分区方法.该方法按照道路、河流等自然障碍将供电区域划分成若干网格,以变电站为生成元向四周扩散.考虑变电站的负载能力、供电距离、地理障碍和网格归属地等因素,动态调整V图生成元在不同方向上的扩算速度,使得供电分区的结果更加科学合理.为了保证分区结果与城市规划的协调性,体现配电网发展的延续性,引入了虚拟元的概念,解决分区内无电源点问题.最后经实际算例验证,表明该方法具有一定有效性和合理性.

A distribution network partitioning method based on adaptive weighted Voronoi diagram is proposed for the uneven load distribution network after researching the application of conventional Voronoi diagram. According to the natural obstacles like roads, rivers, etc., this method divides the power supply regions into several grids and takes substation as the generator to spread around. The expansion speed represented as weight of generator in each direction is dynamically according to the substation load capacity, power supply distance, geographical barriers and management attribution to make the division more reasonable. The concept of virtual generator is introduced in order to achieve the coordination of the partition and urban planning and embody the continuity of distribution network development, and the problem of the partitions without power supply source is solved. An actual example is used to verify the validity and rationality of the proposed method.
