dc.description.abstractU disertaciji je predložen algoritam za proračun kratkih spojeva zasnovan na korelisanim intervalima. U savremenim distributivnim mrežama postoje različiti tipovi generatora koji proizvode električnu energiju iz energije obnovljivih izvora. Za takve generatore, kao i za potrošače, karakteristično je to što je njihova proizvodnja i potrošnja neizvesna. Predloženi algoritam u disertaciji uvažava te neizvesnosti, kao i korelacije između navedenih elemenata. Neizvesnosti su modelovane intervalima i direktno su uvažene u predloženom algoritmu za proračun kratkih spojeva. Algoritam je prvenstveno razvijen za proračun kratkih spojeva savremenih distributivnih mreža sa velikim brojem distribuiranih generatora i potrošača. NJime je moguće proračunavati režime sa kratkim spojevima distributivnih mreža velikih dimenzija, što je numerički verifikovano u disertaciji. Predloženim algoritmom se dobija režim distributivne mreže sa kratkim spojem koji je realističniji od režima dobijenih algoritmima sa determinističkim pristupom. Proračuni kao što su: koordinacija, podešenje i provera osetljivosti relejne zaštite, provera kapaciteta prekidača i osigurača, lokacija kvara itd. mogu na osnovu realističnijeg režima, dobijenog predloženim algoritmom, da daju kvalitetnije rezultate, što je numerički potvrđeno na primeru koordinacije prekostrujne zaštitesr
dc.description.abstractIn this dissertation an algorithm for correlated intervals-based short-circuit calculation is proposed. In modern distribution networks there are various types of generators that produce electric energy from renewable energy resources. For these generators, as well as loads, uncertain production and consumption is characteristic. The proposed algorithm in the dissertation deals with above-mentioned uncertainties, as well as correlations among them. The uncertainties are modeled with intervals and directly taken into account in the proposed algorithm for short-circuit calculation. The algorithm is primarily developed for short-circuit calculation in modern distribution networks with a great number of distributed generators and consumers. The proposed algorithm enables calculation of short circuits states of large-scale distribution networks, which is numerically verified in the dissertation. The proposed algorithm provides short circuit state of distribution network which is more realistic than the one obtained with algorithms with deterministic approach. Calculations such as: coordination, settings and sensitivity check of relay protection, breaker and fuse capacity check, fault location, etc. can give better results, on the basis of the more realistic state obtained by the proposed algorithm for short circuit calculation, which is numerically confirmed by the example of coordination of overcurrent protection.en
