摘　　要：介绍非正弦波形下各种无功功率的定义及其相关公式的证明，指出时域无功功率定义最佳，频域无功功率不能计及电压电流不同形部分的无功功率，畸变无功功率的物理概念是不清楚的，容易混淆。This article gives introduction about different definitions of reactive power under non-sinusoidal waveformssome correlative formulas have been proved．After analysis with examplesexplains why the reactive power definition for time domain is the best．The reactive power for frequency domain could not calculate all parts of reactive power for unlikeness waveforms between voltage ＆ current．The physics conception of distortion reactive power is not clearand may be mixed up．
