摘　　要：文章中的串联型有源滤波器是与无源滤波器配合使用的 ,它除了可以改善无源滤波器的滤波效果之外 ,还可以同时补偿三相中点接地系统中的电源电压不平衡。提出的检测电流谐波和电压中负序零序分量的方法都基于瞬时无功功率理论 ,检测算法较为简单并且实时性好。The series active power filter in this paper operat es with a resonant LC passive filter, which can not only improve the effect of pas sive filter, but also compensate load voltage unbalance in three phase system wi th neutral point connect with ground. The proposed method that check current har monics and voltage unbalance components is based on instantaneous reactive power theory, it is simple and with a short delay. Simulation results prove validity o f the method.
