摘　　要：针对当前低压配电网无功补偿量与需求量相差较大,无法保证低压配电网稳定运行的问题,本文引入自适应粒子群算法,对无功补偿方法展开设计研究。计算异常低压配电网的偏移量;建立以低压配电网稳定运行为目标的无功补偿目标模糊函数;利用自适应粒子算法对无功谐波潮流描述,对所需电子量进行协同优化配置,实现无功补偿。通过对比实验证明,设计的无功补偿方法与基于虚拟线路的无功补偿相比补偿精度更高,无功补偿量与需求量之间差值均控制在0.005Mva以下,能够在极大程度上保障低压配电网的稳定运行。For the problems of much difference of reactive compensation quantity and quantity demanded of a low voltage distribution network and unable to ensure stable operation of the low voltage distribution network.The adaptive particle swarm algorithm is introcluced in the paper, which carries out design and study for the reactive compensation method.calculate deviation quantity of the abnormal low voltage distribution network and set up fuzzy function of reactive compensation abjective as stable operation of the low voltage distribution network.Use the adaptive particle algorithm to describe reactive harmonic current and take requred electron quantity coordinated optimization achieve reactive compensation.The contrast experiments show that the accuracy of the designed reactive compensation is higher than that of the reactive compersation based on virtual lines.The differential values between the reactive compensation quanlity and required quantity are controlled 0.005 Mva below, which can qreatly ensure stable operation of the low voltage distribution net work.
