摘　　要：提出了一种直接依据矢量运算的通用瞬时功率理论,首先以三相系统为例给出了三相系统中各瞬时值的通用定义,然后详细分析和证明了各定义量的相互关系和性质,并将这种定义和性质推广至任意相电路。最后,阐明了通用瞬时功率理论的物理意义。A new kind of universal instantaneous power theory is presented, which is directly based on vector operation. Firstly, the three-phase system is set as an example to give universal definition of instantaneous values. Then, the relationship and the nature of the definitions are analyzed and proved in detail. Moreover, the definition and the nature are extended to anyphase circuit. Finally, the physical meaning of the universal instantaneous power theory is clearly clarified.

关 键 词：瞬时功率 无功定义 三相电路
