Abstract

U radu su opisani kvarovi i smetnje koji mogu nastati za vrijeme pogona energetskog postrojenja te djelovanje tih kvarova na elemente. Također, ukratko su opisani načini zaštite dijelova postrojenja od poremećaja koji se u njemu mogu dogoditi. Posebno je opisana zaštita VN i SN vodova, zaštita transformatora, sabirnica i zaštita od zatajenja prekidača. Osim električkih opisane su ostale zaštite transformatora. Napravljena je analiza zaštite u stvarnom postrojenju, transformatorske stanice Zabok 110/35(20)/10 kV. Prikazane su vrste zaštite, opis korištenih uređaja te podešenja njihovih zaštitih, mjernih, nadzornih i upravljačkih funkcija.

Abstract (english)

This paper describes the faults and disturbances that may arise during the operation of the energy facility and the effect of these failures on the elements. Also, it briefly describes how to protect the system components of the disorder that can happen. Particularly, it is described protection of HV and MV power lines, transformer protection, bus and breaker failure protection. Apart from electrical, there are also described other transformer protection. The paper includes an analysis of protection in the Electrical power substation Zabok 110/35 (20) / 10 kV., types of protection, a description of the device and settings of their protecting, metering, monitoring and control functions.
