摘　　要：针对目前低压配电网中普遍存在的三相不平衡问题,综述了其抑制方法,以期找到一种经济、可行、有效的方法降低三相不平衡对配电网的危害。简要分析了三相不平衡对配电网经济运行和安全稳定运行的影响,在总结国内外研究与实践的基础上,对目前配电网三相不平衡主要抑制方法中的负荷相序平衡、配网重构、负荷补偿进行了详细地归类分析与评价。最后提出了负荷补偿将是未来解决三相不平衡问题的有效方法,为解决配电网三相不平衡问题提供了一定的借鉴。Aiming at the problem of three-phase unbalance which is widely existed in low-voltage network currently,this paper summarizes its suppression methods so as to find out an economic,feasible and effective way to reduce the damage of distribution network brought by three-phase unbalance. First of all,the influence of three-phase unbalance on the economical,safe and stable operation of power distribution network is analyzed in brief. Based on the summary of research and practice home and abroad,a detailed analysis and evaluation on the main methods for inhibiting the three-phase unbalance of power distribution network,which is load phase sequence balance,distribution network reconstruction,and load compensation is made. Finally,this paper suggests that the load compensation will be an effective method to solve the problem of three-phase unbalance in the future,providing certain reference for solving such problems.
