Abstract
Kratki spoj u elektroenergetskim sustavima i postrojenjima je učestala pojava koja dovodi do velikih mehaničkih i toplinskih naprezanja te su proračuni stanja kratkog spoja od iznimne važnosti za normalno funkcioniranje sustava. U radu je izložena teorijska analiza nastanka kratkog spoja, uključujući vrste koje nastaju u mreži, njihovih strujno – naponskih prilika, preko najznačajnijih struja koje se pojavljuju prilikom kratkog spoja. Fizikalne osnove su detaljno opisane kao sastavni dio teorijske analize. Kao ključni dio diplomskog rada prikazana je numerička analiza kratkog spoja jednostrano i dvostrano napajane mreže te isti sustavi simulirani programskim paketom Easy Power, zajedno s analizom i usporedbom generiranih rezultata.

Short circuit in power systems and plants is a common phenomenon which leads to high mechanical and thermal stresses, therefore calculations of the short-circuit are of the utmost importance for the normal functioning of the system. This paper is a theoretical analysis of the occurrence of a short circuit, including types that occur in a network, with their current - voltage conditions and the major currents that occur when a short circuit is present. Principles of physics are described in detail as part of the theoretical analysis. Main part of the thesis shows the numerical analysis of a short circuit on unilaterally powered and double powered network, and those systems simulated using the software package Easy Power, followed by an analysis and comparison of the results generated.
