摘　　要：针对35kV/10kV两级变电站综合规划模型,提出了一种基于遗传算法的负荷转移方法。利用遗传算法通过两级分别规划和直接35kV变电站规划这两种方式进行两级变电站供电范围的划分,找出其中的边界负荷。对边界负荷进行有效转移求取介于两种方式间更优的供电范围划分方式并由此得到变电站规划方案。该方法综合考虑了两级变电站间供电范围的影响,能够得到两级分别规划时难以找到的最优解。算例分析结果证明了该方法的有效性和可行性。kV/10 kV substation integrated planning models are analyzed and a load transfer method based on genetic algorithm is presented. Two planning methods are applied to divide the supply areas for 35 kV and 10 kV substations:separately for each grade and straight for 35 kV substations. The margin loads are emerged. Then,by effective transfer of them,a better division of the supply areas is obtained and the planning scheme is achieved. The proposed method considers the influences on power distribution of both voltage grades and gets the optimal mode,which could be found in separate planning. The example results show its validity and feasibility.
