摘　　要：概述了三相不平衡的概念,并采用对称分量法推导出线损与三相不平衡度的关系,通过对典型三相不平衡的线损增加率计算,论述了三相负荷不平衡对线损的影响,并提出降低线损率的办法和思路。Overviewed the concept of three-phase imbalance,and used symmetrical component method to deduce the line loss and three-phase imbalance degree of relationship,through the calculation of typical unbalanced three-phase line loss increase rate,discussed the influence of three-phase unbalanced load on line loss,and put forward ways to reduce the line loss.

关 键 词：三相四线制 三相负荷不平衡 线损率 降低线损
