| Abstract | |
The ability to individually extract different types of disturbances present in AC line currents or voltages is desirable for reference signal calculation algorithms employed in power conditioners, in order to optimize the operation and design of power converters. This paper proposes a novel algorithm based on the dot product of three-dimensional space vectors in the abc coordinate system, for real-time calculation of the instantaneous positive-, negative-and zero-sequence components for individual harmonics. Certain applications are presented, including individually compensating the fundamental reactive power, selected current harmonics and current unbalances. This method is computationally simple and requires no coordinate transformation. The proposed algorithm is validated by simulation and experiments. (AU) | |
