RELAY PROTECTION OF 220 kV LINES IN KONJSKO 400/220/110/10 kV SUBSTATION

Naziv ovog završnog rada je “Relejna zaštita vodova 220 kV u TS 400/220/110/10 kV Konjsko”. U radu su izvršeni proračuni podešenja relejne zaštite vodova 220 kV. Napravljen je izbor funkcija zaštite koje će se koristiti u slučaju nastupa međufaznog kratkog spoja te zemljospoja, kao i konkretnih podešenja korištenih funkcija zaštite. Pri proračunima su uvaženi svi osnovni kriteriji kvalitetnog rada relejne zaštite. Valja naglasiti da kvalitetan rad sustava relejne zaštite doprinosi kvalitetnom funkcioniranju EES-a u cjelini.The title of this final paper is "Relay protection of 220 kV lines in 400/220/110/10 kV Konjsko substation". The calculations were made for adjusting the relay protection of 220 kV lines. A choice has been made of the protection to be used in the event of an interphase short circuit and an earth fault, as well as the specific settings of the protection functions used. All basic criteria of quality workforce are taken into account in the calculation. It should be emphasized that the quality of the work the relay protection system contributes to the smooth functioning of the power system as a whole
