САЖЕТАК / ABSTRACT:
U radu se razmatraju osnovne šeme napojnih vodova (fidera) koje se koriste u gradskim distributivnim mreţama sa stanovišta ekonomičnosti, pouzdanosti i tehničkih ograničenja. Prikazani su matematički modeli za analizu godišnjih troškova vodova, pouzdanosti, padova napona i dozvoljenih opterećenja u normalnim i kritičnim havarijskim situacijama. Oni su upotrebljeni za utvrđivanje tehničkih granica različitih rešenja u pogledu preseka provodnika kablova, njihovih dužina i broja potrošačkih TS koje napajaju. U proračunima se uzima u obzir nesigurnost nekih ulaznih podataka predstavljajući ih sivim brojevima koji mogu da imaju svaku vrednost unutar pretpostavljenih granica. Razvijeni matematički modeli korišćeni su u analizi tehničko-ekonomskih karakteristika razmatranih šema kod primene u 10 kV mreži Beograda.
