摘　　要：本文指出赤木三相瞬时无功功率理论的实质,相当于三相90度接线的无功功率表,当三相电压含有谐波和不对称时,不能正确反映三相无功功率总和,且由此导出的p、q分解法也不能完全消除谐波。本文同时给出用d、q矢量变换进行谐波、不对称、无功功率治理的完备公式。This paper points that the essence of three-phase instantaneous reactive power theory presented by H. Akagi. It is corresponding to three-phase 90-degree connection for reactive power meter. It can＇t reflect the three phase summation of reactive power as there is harmonic ＆ asymmetry in voltages, and p/q decomposing method exported from which can not entirely eliminate harmonic. This paper also transform to remove harmonic, asymmetry and reactive power out from the system.

关 键 词：瞬时无功功率 谐波 不对称
