20.500.12556/DKUM-48335 REŠEVANJE NAPETOSTNIH RAZMER V NN-OMREŽJU S POMOČJO TRANSFORMACIJE SN NA 1 kV SOLVING OF VOLTAGE CIRCUMSTANCES FOR LOW VOLTAGE GRID WITH THE HELP OF MIDDLE VOLTAGE TO 1 kV TRANSFORMATION Prevelik padec napetosti v večini primerov najbolj prizadene končne porabnike. Vsakdo izmed njih ima pravico do nemotene oskrbe z električno energijo. Za izboljšanje napetostnih razmer sta v nalogi opisana in predstavljena dva načina. Ena izmed rešitev je napetostni stabilizator, katerega delovanje je uvodoma natančneje opisano. Prav tako je opisana tudi druga rešitev, transformacija na 1 kV napetostni nivo. V drugem delu naloge so predstavljeni posamezni postopki modeliranja omrežja. Tako ena kot druga rešitev imata svoje prednosti in slabosti. V zadnjem delu so prikazani rezultati simulacij ter kratke ugotovitve smiselnosti reševanja napetostnih razmer za oba načina. The most affected by a too high voltage drop in the majority of cases are the final consumers. They have the right to obtain the undisrupted voltage supply. In this paper are described and presented two ways of solutions in order to improve voltage conditions. One solution is a voltage stabilizer, the functioning of which is initially described in detail. The other solution is transformation to 1 kV voltage level. Hereinafter are presented some processes of network modelling. Both solutions have their advantages and disadvantages. The final section presents the results of simulations and the sense of using the described solutions. napetostni stabilizator padec napetosti transformacija napetosti magnet voltage booster voltage drop transform voltage true true false [M.
