Abstract

Ena izmed osnovnih nalog elektrodistribucijskih podjetij je zagotavljanje nemotene oskrbe z električno energijo in ustreznih padcev napetosti znotraj predpisanih mej. Neustrezni napetostni profili v nizkonapetostnem omrežju najbolj vplivajo na končne porabnike. V magistrski nalogi je predstavljeno trenutno stanje pri napajanju oddaljenih odjemalcev, ki so napajani z napetostjo 0,95 kV. Za zagotavljanje ustreznih napetostnih razmer so predstavljene in ovrednotene štiri izvedbe napajanja, in sicer napajanje z 0,4 kV, napajanje z 0,95 kV, napajanje z 0,4 kV in napetostnim stabilizatorjem ter napajanje z 0,4 kV in baterijskim sistemom. S pomočjo izdelanih simulacijskih modelov omrežja smo izvedli analizo napetostnih razmer, analizo izgub električne energije in ekonomsko analizo. Na koncu smo posamezne rešitve ovrednotili in medsebojno primerjali.

Secondary title: Providing proper voltage conditions in low voltage networks
Secondary abstract: One of the basic tasks of electrical distribution companies is to ensure constant supply of electrical energy and proper voltage conditions in networks within prescribed limits. Inadequate voltage profiles in low voltage networks have the greatest impact on end users. Master's thesis presents current status of power supply for remote users that are powered with 0,95 kV. Provision of appropriate voltage conditions is presented for four different power supply solutions, which are power supply with 0,4 kV, power supply with 0,95 kV, power supply with 0,4 kV with voltage booster and power supply with 0,4 kV with battery system. Based on simulation models of the discussed network, we analysed voltage conditions and electrical energy losses. We also performed economic analysis for each of the four presented solutions. Lastly, we evaluated them and compared them to each other.
