Abstract

V tem diplomskem delu je obravnavan vpliv bližinskega pojava na posameznih elementih elektroenergetskega sistema in zmanjševanje le-tega. Na osnovi numeričnega izračuna po metodi končnih elementov smo izvedli analizo sosedstvenega pojava za nekaj osnovnih elementov v elektrotehniki kot so: vodniki, kabli, tuljavica in tuljava za velike tokove. V nadaljevanju je prikazana raziskava zmanjšanja vpliva sosedstvenega pojava na primeru votlih vodnikov za velike tokove. Končni cilj te diplomske naloge pa je s pomočjo optimizacijskega algoritma PSO (Particle Swarm Optimization) določiti takšno geometrijsko obliko, da pri tem zmanjšamo vpliv sosedstvenega pojava, pri čemer smo numerični izračun magnetnega polja izvedli s programskim paketon EleFAnT. Optimirani parametri so geometrijske koordinate osi votle notranjosti vodnika.

Secondary title:	Reducing the proximity effect with using optimization algorithm
Secondary abstract:	This assignment studies the effect of the proximity effect on certain elements of the electromagnetic system and the reduction of said. On the basis of numeric calculation with the finite element method we performed an analysis of the proximity effect for the some basic electrotehnic element such as: line, cables, coils and high amperage coils. The following research shows the reduction of the proximity efect on an example of hollow cables for high amperage. The goal of this assignment is to determine the geometric shape which reduces the proximity effect the most with the help of the Particle Swarm Optimization (PSO). We performed the numeric calculation of the magnetic field with the help of the EleFAnT software. The optimal values are the geometric coordinates of the hollow inner part of the cable.
