| Abstract |
This paper proposes a unified definition of powers for various circuit conditions such as
balanced/unbalanced, sinusoidal/non-sinusoidal, and linear/nonlinear, for single-phase systems and threephase
systems. Conventional reactive power is more classified into an interactive power and a scattering
power. These powers are defined both in 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 circuits in the single-phase and three-phase systems. Simulation results show the power quality factors can evaluate and classify the various circuit conditions explicitly. |
