摘　　要：用三种方法讨论了三相电路中瞬时电流和功率的分解和定义 ,阐述了这三种方法的相互联系 ,说明了各分量的物理意义和在矩阵Three methods are used to discuss the decomposition and definitions of instantaneous currents and powers in three-phase circuits. The relations among these methods are explained. The physical meanings of all components and their geometrical meanings in matrix-vector approach are also illustrated. Park transform is used to analyse their relations.

关 键 词：瞬时无功电流 瞬时无功功率 PARK变换
