 Abstract

This paper proposes an unified definition of powers for various circuit conditions such as balanced/unbalanced, sinusoidal/non-sinusoidal, and linear/nonlinear, for single-phase systems and three-phase systems Conventional reactive power is more classified into an interactive power and an alternating power These powers are defined both m the time domain and the frequency domain consistently, and agree well with the conservation law Several important power quality factors are defined to measure and evaluate the power quality for the various circultc in the single-phase and three-phase systems. simulation results show the power quality factors can cvaluate and classify the various circuit conditions clearly.
