Proračun podešenja zaštitnih funkcija novih elemenata 500 kV prenosnog sistema
Calculation of protection function settings of new elements of the 500 kV transmission system
Sažetak
U ovom radu prikazan je proračun podešenja zaštitnih funkcija elemenata prenosnog sistema. Analizirani prenosni sistem čine elementi 500 kV i 230 kV naponskog nivoa. Dat je proračun podešenja pojedinih zaštitnih funkcija 500 kV reaktora, 500/230 kV/kV auto-transformatora i 500 kV dalekovoda. Modelovanje mreže i analize vršene su u softverskom paketu DlgSILENT PowerFactory.
Abstract
In the paper the protection function setting calculations for elements of the transmission system are shown. Analyzed transmission system consists of the 500 kV and 230 kV voltage levels. The setting calculations are shown for several protection functions for the 500 kV reactors, 500/230 kV/kV autotransformers and 500 kV line. Network modeling and analysis have been performed using DIgSILENT PowerFactory.
