摘　　要：由三种瞬时功率的定义出发,利用自由度观点和能量守衡原理,对各种瞬时功率理论各自特点进行分析比较,通过带不对称负荷的电路仿真验证论文的结果.研究结果表明:传统瞬时功率理论在全局补偿中有优势;改进瞬时功率理论较适用于对各种谐波分量进行精细补偿的场合;p-q-r坐标下的瞬时功率理论具有功率守恒和无功功率相互独立的特点,适用于独立无功补偿的场合.The paper began with the definitions of the instantaneous power theories, then came to the conclusion that： traditional instantaneous power theory is useful in total compensation, adapted instantaneous power theory is valuable in precise current compensation, while instantaneous power theory defined in p - q - r , which is conserved and reactive power independent, is important in reactive power separately compensation.
