摘要
基于将传统功率理论中有效值、相位差、有功功率和无功功率等概念向瞬时值概念的自然扩展，建立了三相电路瞬时无功功率理论与传统功率理论的统一数学描述，深入分析了二者之间的关系，揭示了瞬时无功功率理论的物理意义。
This paper makes detail analysis on the relationship between instantaneous reactive power theory and conventional power theory in three phase circuits.The analysis is based on the natural extension of the concepts in conventional power theory,such as effective value,phase angle difference,active power and reactive power,to the concepts of instantaneous value.Through this extension,the uniform mathematical description of the instantaneous reactive power and conventional power is established.The physical meaning of the instantaneous reactive power theory is explicitly explained,and the relationship between the two power theories is clearly revealed,both in the aid of a profound understanding of the uniform mathematical description.
