Abstract:Cilj magistrskega dela je izračun temperaturnih koeficientov za numerični model ohišja stikalne celice. Za boljše ovrednotenje rezultatov so bile na poenostavljenem realnem modelu predelne stene stikalne celice izvedene vse potrebne meritve za medsebojno primerjavo med obema modeloma. S programskim orodjem Matlab in EleFAnT so bili izvedeni vsi izračuni v magnetnem in v termičnem polju. Z uporabo optimizacijskega algoritma diferenčne evolucije (angl. differential evolution) so bili izračunani temperaturni koeficienti (toplotna prevodnost in toplotna prestopnost). Zaradi boljše preglednosti in enostavnejše uporabe programa je bil v Matlabu izdelan grafični vmesnik, ki ponuja nešteto možnosti pri nastavitvah različnih parametrov. Rezultati so prav tako prikazani z grafičnim vmesnikom, ta pa nudi uporabniku različne vrste izrisov (grafi, histogrami, slike) in izpisov. Poudarek magistrskega dela je bil čim bolje sestaviti numerični model stikalne celice, tako da bi bili dobljeni rezultati praktično identični z realnim modelom. Meritve so bile izvedene na Mariborskem otoku v Infrastrukturnem centru za energetske meritve (ICEM).

Title:OPTIMIZATION ALGORITHM USED FOR THERMAL COEFFICIENTS CALCULATION IN NUMERICAL MODEL OF SWITCHGEAR CELL HOUSING
Abstract:Aim of this master thesis is a calculation of thermal coefficients on the basis of the numerical model of switchgear cell housing. For a better evaluation of the results all the necessary measurements for a mutual comparison between both models were made on a real model. All measurements in the magnetical and thermal field were made with the programs Matlab and EleFAnT. With the use of optimization algorithm – differential evolution the temperature coefficients (terminal conductivity and heat transfer coefficient) were calculated. A graphical user interface, which offers many options within the settings of different parameters, was made in Matlab because of a better view and an easier use of the program. The results are also presented with the graphical user interface, which offers different plots (graphs, histograms and pictures). The emphasis of the master thesis was to construct the numerical model of the switchgear cell housing in that way that the given results would be practically identical with the real model. The measurements were made on Mariborski otok at the Infrastructural Center for Energy Measurements (ICEM).
Keywords:optimization, graphical user interface, thermal conductivity, heat transfer coefficient, eddy curent, finite element method
