Abstract:Diplomska naloga analizira vpliv varčnih sijalk na celostno harmonsko popačenje (THD) tokov in napetosti, kakor tudi na izgube povezane s prenosom električne energije v distribucijskih omrežjih nizke napetosti. Potrebni testi in meritve so izvedeni v nadzorovanih pogojih. Vpliv drugih elementov električnega omrežja na rezultate meritev je izločen z uporabo v ta namen sestavljenega eksperimentalnega sistema, ki je izoliran od električnega omrežja. Sestavni elementi eksperimentalnega sistema so vodeni napetostni vir, linearna in nelinearna bremena v obliki varčnih sijalk in žarnic, pa tudi vodniki, ki povezujejo napetostni vir z bremeni. Vodeni napetostni vir zagotavlja enofazne in trifazne napajalne napetosti z majhnim celostnim harmonskim popačenjem ne glede na značaj bremena. Uporabljen je bil za napajanje enofaznih in trifaznih bremen sestavljenih iz varčnih sijalk in žarnic. Na priključnih sponkah vira napetosti in bremen izmerjeni toki in napetosti so bili uporabljeni za ovrednotenje vpliva varčnih sijalk in žarnic na izgube povezane s prenosom električne energije in na celostno harmonsko popačenje tokov in napetosti.

Title:IMPACT OF COMPACT FLOURESCENT LAMPS ON LOW VOLTAGE DISTRIBUTION NETWORK
Abstract:The diploma thesis investigates the impact of compact fluorescent lamps (CFLs) on the total harmonic distortion (THD) of currents and voltages as well as losses related with the energy transmission in low voltage distribution networks. The required tests and measurements are performed under controlled conditions. The influence of the distribution network elements not considered in the investigation on obtained results is eliminated by building up an experimental set-up insulated form the electric grid. The experimental set-up consists of a controlled voltage source, linear and nonlinear loads in the form of CFLs and incandescent lamps (normal bulbs) (ILs), and connection lines between the voltage source and loads. The controlled voltage source is able to generate single- and three-phase sinusoidal supply voltages with low THD regardless on the load character. It was used to supply linear and nonlinear single- and three-phase loads composed of CFLs and ILs. Voltages and currents were measured on the terminals of the voltage source and loads. They were used to evaluate the impact of CFLs and ILs on losses related with energy transmission and THDs of currents and voltages.
Keywords:compact fluorescent lamps, total harmonic distortion, losses, distribution network, measurements
