Abstract:Cilj magistrskega dela je bila primerjava, ki zajema toplotno in elektromagnetno polje med daljnovodom ter kablovodom. S programskim orodjem Matlab in EleFAnT smo na osnovi numeričnega izračuna po metodi končnih elementov izvedli izračune termičnega in elektromagnetnega polja. Pridobljene rezultate smo primerjali z vrednostmi, ki jih navaja Uredba. Rezultati so prikazani z grafičnim vmesnikom, ki nudi uporabniku različne vrste prikazov (slike, grafi in histogrami) in izpisov. Analizirali smo tudi finančno plat gradnje daljnovoda oz. položitve kablovoda. Poudarek magistrskega dela je bil na kreiranju čim bolj realnih numeričnih modelov, pri čemer smo upoštevali veličine, ki nastopajo pri realnih modelih (vpliv vetra, debeline posameznih slojev, različni koeficienti ipd). Le na tak način so dobljeni rezultati primerljivi z realnimi.
Keywords:daljnovod, kablovod, temperaturno polje, elektromagnetno polje, metoda končnih elementov.

Title:COMPARISON BETWEEN ELECTROMAGNETIC AND THERMAL LOST FOR OVERHEAD AND CABLE POWER LINES USING FEM
Abstract:The purpose of the master thesis has been a comparison between thermal and electromagnetic field between an overhead line and underground cable. We have implemented calculations of thermal and electromagnetic field based on numeric calculations with finite element method using program tools Matlab and EleFAnT. We have compared the gained results with the values of the Decree. The results have been shown by a graphic interface which offers the user different sorts of presentations (pictures, graphs, and histograms) and copies. We have also analysed the financial side of the overhead line or underground cable construction. The purpose of the master thesis has been to create as realistic numeric models as possible where we have abided quantities of the real models (the influence of wind, thickness of the individual layers, different coefficients, etc.). This is the only way we can compare the results with realistic ones.
Keywords:overhead line, underground cable, thermal field, electromagnetic field, finite element method.
