Abstract

Postupak reguliranja pretvarača mrežne struje (3) za pružna vozila, pri čemu se mrežna struja (iNetz) učitava na pretvarač mrežne struje preko transformatora (2) pomoću strujnog kolektora (1) koji preuzima mrežni napon (UNetz) iz jednofaznog izmjeničnog glavnog dobavljača struje, a konstantni intermedijerni izravni napon (ud) se proizvodi na izlaznoj strani pretvarača mrežne struje (3), pri čemu se izravno-strujna komponenta mrežne struje (iNetz) na primarnoj strani transformatora otkriva pomoću pogodnih mjernih i analitičkih uređaja (8, 9, 15 i 8a, 9a, 15a), te da je nominalna vrijednost izravne struje (iQSoll,DC) koja odgovara izravno-strujnoj komponenti, položena iznad nominalne vrijednosti struje (iQSoll) strujnog regulatora sa sekundarne strane (12) od pretvarača mrežne struje (3), na takav način da izravna struja sekundarne strane postavljena pomoću strujnog regulatora (12) djeluje protivno pred-magnetizaciji transformatora (2), naznačen time, da se u detektoru pred-magnetizacije (13) određuje indikator cjelokupnog vremena druge harmoničke oscilacije mrežne struje (iNetz) pomoću odijeljene Fourier-ove transformacije, a da se opseg pred-magnetizacije određuje kao amplituda indikatora toga vremena, te da se smjer pred-magnetizacije određuje od faznog kuta druge harmoničke oscilacije mrežne struje (iNetz) prema temeljnoj oscilaciji mrežnog napona (UNetz), te time da, nadalje, opseg i smjer pred-magnetizacije se učitavaju na regulatoru pred-magnetizacije (14), te time, da se iz tih podataka određuje nominalna vrijednost izravne struje (iQSoll,DC) u tom regulatoru pred-magnetizacije (14) za strujni regulator (12) od pretvarača mrežne struje (3). Patent sadrži još 6 patentnih zahtjeva.
