Abstract:V sodobnih nizkonapetostnih omrežjih opažamo vedno večje zahteve po električni energiji in slabšanje kakovosti napajalne napetosti. V diplomski nalogi smo predlagali različne ukrepe za izboljšanje kakovosti napetosti. Posebej smo obravnavali regulacijo proizvedene jalove moči s fotonapetostnimi elektrarnami, uporabo baterijskih hranilnikov in dvig napajalne napetosti na nizkonapetostni strani transformatorja. Za realno omrežje s 55 odjemalci smo opravili stacionarne izračune, s katerimi smo določili napetostni profil omrežja in toke skozi vodnike. Opravili smo tudi dinamične izračune upadov napetosti zaradi zagonov toplotnih črpalk. Iz dobljenih rezultatov sklepamo, da bo v prihodnosti uporaba obravnavanih ukrepov igrala veliko vlogo za zagotavljanje ustrezne kakovosti napajalne napetosti.

Title:Voltage quality improvement in modern low-voltage networks
Abstract:Proliferated integration of modern elements in low voltage (LV) networks causes a growing demand for electrical power and degradation of voltage quality. In our thesis, we suggested different methods for improving the voltage quality in the LV network. We focused on the impact of regulation of the reactive power generated by photovoltaic power plants, usage of battery storage systems, and increasing the output voltage of a power transformer. We conducted simulations on a quasy-static model of a network with 55 customers and evaluated voltage profiles and currents in the network. We also simulated how the heat pump start-ups affect the voltage drops in a dynamic model. From the simulation results, we conclude that in the future, the use of the aforementioned measures will play an essential role in providing a quality supply voltage for all LV users.
Keywords:voltage quality, low-voltage network, modern elements of low-voltage networks, load flow calculations, dynamic calculations
