THE IMPACT OF STREET LIGHTS ON ENERGY TRANSMISSION LOSSES AND POSSIBILITY FOR REALIZATION OF ENERGY SELF-SUFFICIENT STREET LIGHTING

Diplomsko delo je razdeljeno na dva dela. V prvem delu je predstavljen vpliv ulične svetilke v LED tehnologiji na izgube pri prenosu električne energije, drugi del vsebuje analizo in izdelavo energetsko samozadostne ulične svetilke. V prvem delu smo opravili analizo na podlagi laboratorijskih meritev. Za opravljanje meritev smo uporabljali napetostni vir z nizkim harmonskim popačenjem. Zajemanje podatkov je bilo izvedeno z ustreznimi tokovnimi in napetostnimi senzorji in krmilno enoto dSpace. Meritve smo opravili za LED ulično svetilko znanega slovenskega proizvajalca. Rezultate meritev smo prikazali in obdelali s pomočjo programskega paketa Matlab. V drugem delu naloge smo izdelali dva primera energetsko samozadostne ulične svetilke, ki ni priključena na elektroenergetsko omrežje, ter ju analizirali.The diploma thesis has two parts. The first part evaluates the impact of street LED lights on energy transmission losses while the second part deals with the analysis of energy self-sufficient street lights and manufacturing of two energy self-sufficient street lights. In the first part, an analysis based on laboratory measurements is performed. To perform the measurements, a voltage source with low total harmonic distortion is used. Data acquisition was performed with appropriate current and voltage sensors and control unit dSpace. Measurements were performed on LED street lamp of well known Slovenian manufacturer. For data processing and presentation of results the sofware package Matlab is used. Two examples of energy self-sufficient street lamps, which are not connected to the electrical grid were manufactured, in order to analyse their opreration and performances
