Sažetak
U ovom radu analiziran je uticaj pojave zasićenja strujnih transformatora, usled struja kvarova velikih vrednosti u sistemu, na talasni oblik struje na sekundaru strujnih transformatora, kao i analiza rada diferencijalne zaštite transformatora u takvim uslovima. Analize su vršene na softverskom modelu zaštitnog uređaja, a potom i na stvarnom uređaju injektiranjem odgovarajućih signala na njegove ulaze, primenom ispitnog kofera za ispitivanje zaštitnih uređaja. Potom je izvršena komparacija odziva softverskog modela i stvarnog uređaja. Modelovanje mreže i analize vršene su u softverskom paketu DlgSILENT PowerFactory, a ispitivanja zaštitnog uređaja su vršena pomoću DOBLE ispitnog kofera.
Abstract
In the paper the analyses of the current transformer saturation influence to operation of differential protection are presented. Analyses are performed using a simulation tool and a relay model, as well as using the physical relay by injecting test currents from test equipment on relay inputs. The comparison of relay behavior in these two analyses has been performed and discussed. Network modeling has been performed in DIgSILENT PowerFactory and physical relay testing using DOBLE test equipment.
