摘　　要：功率理论是电能计量、电力传输效率评估与电能质量治理的基础之一。现代电力系统日益复杂,谐波不平衡问题日益突出,传统正弦条件下的功率理论不再适用,因此,研究非线性条件下的功率理论具有重要的理论和实际意义。其中,电流物理分量理论(CPC理论)备受关注。文章首先详细概述了CPC理论的内涵,然后结合MATLAB/SIMULINK仿真,对各电流分量及其所代表的物理意义进行了深入分析,指出了其定义的局限性,对重新认识和研究CPC理论,并进一步应用具有重要的借鉴意义。Power theory is one of the foundations for electric energy metering,efficiency evaluation of power transmission and power quality management. Power systems become more and more complex,which exacerbate the unbalance problem of the harmonics. At the same time,the traditional power theory under the sinusoidal condition is no longer applicable. Therefore,the power theory research under the condition of the non-sinusoidal has theoretical and practical significance. Among them,the Currents＇ Physical Component（ CPC） theory is concerned greatly. In this paper,the connotation of the CPC theory is elaborated. Then,with the simulation of MATLAB/SIMULINK,the current components and their physical meanings in the CPC theory are analyzed. At the same time,the limitations of the theory are presented. This is good for the understanding and further study of power theory.
