Abstract:Pogost problem v nizkonapetostnih distribucijskih omrežjih je zagotavljanje ustreznih napetostnih razmer. Oddaljeni odjemalci se največkrat soočajo s prenizko napetostjo zaradi povečanega odjema električne energije predvsem ob koničnih obremenitvah. Članek obravnava 0,4 kV distribucijsko omrežje kjer zaradi povečanega odjema in dolžine vodov ni mogoče zagotoviti ustreznih napetostnih razmer. Takšno omrežje je potrebno rekonstruirati. Za zagotavljanje ustreznih napetostnih razmer so predstavljene tri rešitve, ki so: 0,95 kV napajanje, 0,4 kV napajanje z napetostnim stabilizatorjem in 0,4 kV napajanje z baterijskim sistemom. Posamezne rešitve so podrobneje opisane, analizirane in ovrednotene. Izvedena je analiza napetostnih razmer, izgub električne energije in ekonomska analiza, ki zajema stroške investicije, letne stroške izgub električne energije in letne stroške vzdrževanja. Vse predstavljene rešitve zagotavljajo ustrezne napetostne razmere. Na podlagi naštetih primerjav je izbrana najustreznejša rešitev.

Abstract:A common problem in low voltage distribution networks is the provision of adequate voltage conditions. Remote users are often faced with too low voltage due to increased electricity consumption and peak loads. Article deals with 0,4 kV distribution network where the adequate voltages cannot be provided due to increased consumption and the length of the lines. Such network needs to be reconstructed. In order to provide adequate voltage conditions, three solutions are presented: 0,95 kV power supply, 0,4 kV power supply combined with a voltage booster and 0,4 kV power supply combined with a battery system. Individual solutions are described in detail, analyzed and evaluated. Analysis of voltage conditions, electrical energy losses and economic analysis, including the cost of investment, anual costs of electrical energy losses and anual maintenance costs is made. All presented solutions provide adequate voltage conditions. On the basis of these comparisons, the most appropriate solution is selected.
Keywords:distribution network, supply of remote users, voltage drop, electrical energy losses, voltage booster, battery system
