Safety aspects of photovoltaic power plants

U ovom diplomskom radu obraĎena je tema uzemljenja dvije fotonaponske elektrane. Izvršena su mjerenja otpora uzemljenja na fotonaponskoj elektrani na krovu srednje zgrade Mašinskog fakulteta u Novom Sadu te na fotonaponskoj elektrani u selu Sajan kod Kikinde. Osim mjerenja napravljeni su i modeli navedenih fotonaponskih elektrana u programskom alatu CYMGRD te su izvedene kompjuterske simulacije kvarova u postrojenjima te su promatrane strujne karakteristike instalacija za uzemljenje te utjecaj električnih veličina na osobe koje bi se eventualno nalazile u postrojenju za vrijeme kvara. Dobiveni rezultati su usporeĎeni i interpretirani.Subject matter of this final thesis is grounding of two photovoltaic power plants. Grounding resistance measurements were conducted on photovoltaic power plant on the roof of the middle building of the Machine institute in Novi Sad and on photovoltaic power plant in village Sajan near town of Kikinda. Besides measurements, models of above listed photovoltaic power plants were made in software tool CYMGRD, and computer simulations of short circuit failures were conducted. Characteristics of current for the grounding installations during the short circuit and impact on an eventual bystander were monitored. Collected results were compared and interpreted
