Upravljanje strujom trofaznih paralelno spojenih aktivnih filtara s Äetiri vodiÄa
An active filter has been proposed to compensate for harmonic distortion, line neutral current and reactive power in three-phase four-wire systems. The focus is concentrated on current control in order to achieve optimum current tracking by means of fixed frequency driving signals. The effectiveness of proposed control was proved in simulations where the harmonic pollution and imbalance caused by a highly distorting load have been drastically reduced.Opisan je aktivni filtar za kompenzaciju harmonijskog izobliÄenja, struje nultog sustava i jalove snage u trofaznim sustavima s Äetiri vodiÄa. Pozornost je usmjerena na upravljanje strujom da se postigne optimalno slijeÄenje struje s pomoÄu konstantne frekvencije pobudnog signala. Djelotvornost predloženog upravljanja ispitana je simulacijom, gdje su harmonijsko zagaÄenje i neravnoteža, uzrokovani jakom distorzijom tereta, drastiÄno reducirani
