CPC-Based Minimizing of Balancing Compensators in Four-Wire Nonsinusoidal Asymmetrical Systems

The article presents the possibility of using currents’ physical components (CPC) theory to generate reference current active power filter (APF). solution proposed by authors is based on cooperation minimizing balancing compensators (MBC), which, due their use in 4-wire systems, have been divided into two structures. first compensator, which purpose minimize and balance reactive unbalanced zero sequence, built star system (STAR-MBC). second operation occurs delta (DELTA-MBC), other components, i.e., negative sequence positive sequence. structures cooperating with each significantly reduce currents associated elements, current, current. As mentioned, these are reduced but not compensated or value. In order for compensation bring preferable effect, an APF should be included, will cooperate MBC compensators. This presented this publication. control part hybrid (HAPF), was paper, consists reflection waveform nonsinusoidal approach, no shift relation voltage obtained, waveforms quantities remain distorted. balanced. definition generating a can also used. Through sinusoidal achieved. approach allows additional reduction three-phase RMS value load’s both approaches, flowing through lines reflect amplitude phase asymmetry that present supply voltage. follow changes load conditions correct calculations article, as well waveforms, were created result constructed mathematical models, used theoretical illustrations.
