| Abstract |
This paper proposes a novel power compensation theory in three-phase systems. Three
transformation methods were compared to explain the theory more clearly. Proposed power compensation
theory provides two-degree of freedom to control the system currents by only compensating the instantaneous
imaginary powers without using any energy storage element. This paper proposes a Reference Current
Control method that controls the neutral-line current and the rotating phase currents separately and makes
the system currents sinusoidal and balanced in any circuit conditions such as unbalanced or distorted
voltages and/or unbalanced or nonlinear loads. Simulation results show the superiority of the power
compensation theory both in definition and compensation. |
