三相电路瞬时电流、功率的分解与Park空间分析

Decomposition of instantaneous current and instantaneous power of three-phase circuits and Park space-domain analysis

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.
