摘　　要：针对传统灵敏度方法以补偿前系统的灵敏度值来选择补偿点,常常会造成补偿点分布不均、补偿范围重叠的问题,提出了一种全新的负荷功率阻抗矩法。该方法通过定义负荷功率阻抗矩来表征补偿点的供电范围,按照平均分配阻抗矩的原则确定补偿点,从而保证了补偿点的分布均匀,并具有良好的补偿效果。通过算例仿真,验证了该选点方法的有效性。The traditional method for optimal location of reactive power compensators is based on the sensitivity value of the original distribution network, which often results in non-uniformity of locations and overlapping of ranges. In order to allocate compensation buses more uniformly, a new method called load power impedance moment （LPIM） method is proposed. LPIM is defined and used to stand for the power supply range,then each compensation bus is determined based on the principle of LPIM being apportioned equally, so the compensation locations can be made uniform on feeder line. Digital simulation demonstrates the non-uniformity problem of choosing compensation bus in the traditional sensitivity method and the validity of the proposed method.
