Abstract:V diplomskem delu je predstavljena analiza izgub v distribucijskem omrežju pri obratovanju v zanki. V programskem paketu Matlab/Simulink je sestavljen model distribucijskega omrežja, ki vsebuje tuje omrežje, transformatorja, prenose vode in porabnike. Analiza je izvedena za zanki tipa I in II. Zanko tipa I tvorita v zanko povezana izvoda, ki sta napajana iz sponk istega transformatorja. Zanko tipa II tvorita v zanko povezana izvoda, ki se napajata iz sponk dveh različnih transformatorjev v isti razdelilni transformatorski postaji. Uporabljeni so modeli regulacijskih trifaznih transformatorjev z več odcepi. Za različne nastavitve odcepov transformatorjev so predstavljene izgube v omrežju, ki so določene kot razlike moči na začetkih in na koncih posameznih odsekov vodov.

Title:EVALUATION OF LOSSES IN CLOSED-LOOP ARRANGEMENT OF FEEDERS
Abstract:The diploma thesis deals with the analysis of losses in a distribution network operating with feeders closed in the loop. A dynamic model of the discussed distribution network is built in the program package Matlab/Simulink. It contains models of a network feeder, transformers, power lines and loads. The analysis is performer for the loops of type I and type II. The loop type I is established by connecting two feeders feed by a single transformer while the loop type II is established by connecting two feeders feed by two different transformers from the same substation. The transformer models with tap changers were used. Losses related with energy transmission in the discussed network are determined for different settings of tap changers.
Keywords:distribution network, operation in the loop, losses
