摘　　要：对配网馈线无功优化配置的模型和算法进行研究,提出以年电能损耗费用与折合成等年值的电容器投资成本之和最小为目标的配电网干线无功规划模型,介绍负荷功率阻抗矩法和改进的遗传算法相结合的求解方式,并通过实际算例结果分析,表明该算法无功补偿选点均匀,补偿容量合理,具有良好的降损升压效果。The reactive planning model of the distribution net-work is proposed,in which the obj ective function is to mini-mize the cost of power loss and capacitor investment each year,load power impedance moment method and improved genetic algorithm are comined to sovle the modle,based on the practical distribution network,the simulations demon-strate the efficiency of the proposed algorithm.
