САЖЕТАК / ABSTRACT:
U radu je izložen postupak proračuna struje metalnog trofaznog kratkog spoja na pro- izvoljnom mestu na SN-izvodu na kome su priključeni indukcioni i sinhroni generatori. Pojedinačni odzivi distributivne mreže i pomenutih tipova distribuiranih generatora za slučaj kvara su poznati i oni se međusobno bitno razlikuju. Analiza kvarova u aktivnim distributivnim mrežama se, zbog složenosti postupka, obično sprovodi primenom komercijalno dostupnih programskih paketa.
Korišćenjem pomenutih modela i teoreme superpozicije objašnjeno je kako se izračunavaju struje kvara u vremenskom domenu po svim elementima i deonicama izvoda, uz elementarnu upotrebu računara. Pokazano je da se, bez uticaja na tačnost, neki parametri elemenata sistema mogu zanemariti.
