基于初始站址冗余网格动态减少的变电站规划

针对变电站规划中初始站址对规划结果影响大的问题,提出了一种能自动寻找优良初始站址的简捷有效的新算法.首先,根据可能的变电站个数对规划区域进行冗余网格划分,并以各网格中心作为候选变电站初始站址;然后,基于变电站就近供电原则和舍弃小负载率变电站方法,动态减少变电站个数,找出对应不同变电站个数规划方案的初始站址;最后,引入距离权重因子以便考虑负荷分布不均对变电站负载率的影响,运用交替定位分配法求解各规划方案的站址和站容,并从中选择优化的变电站规划方案.算例表明所述方法可以稳定快速地得到合理的规划结果.

Substation Planning Based on Initial Substation Site Decrease in Redundant Meshes

In view of the significant impact of the initial substation site on the planning results for the substation planning, a new algorithm is proposed to automatically search rational initial substation sites. First, according to the possible number of substations, the planning region is meshed redundantly with the center of a grid as a candidate for the initial substation site. Then, the number of substations should be reduced one by one based on the principle that a substation should preferably be located near...
