Abstract:Cilj magistrskega dela je določitev parametrov dvoplastnega modela zemlje (prevodnosti posameznih plasti zemlje in debeline posameznih plasti zemlje). Uporabili smo dva modela, in sicer numerični in realni. Numerični model smo sestavili s pomočjo metode končnih elementov. Realni model predstavljajo meritve potencialov na površju in v globini testnega poligona. Predvsem rezultati meritev v globini testnega poligona omogočajo natančnejšo določitev parametrov večplastnih modelov zemlje (dvoplastni in več). Določitev oz. izračun parametrov večplastnega modela zemlje smo izvedli s pomočjo optimizacijskega algoritma diferenčne evolucije tako, da je dosežena čim manjša razlika potencialov med obema modeloma (med modelom in meritvami).
Keywords:model zemlje, specifična upornost zemlje, palično ozemljilo, numerični izračun, optimizacija

Title:Calculation of multilayer soil model parameters for operational earthing system
Abstract:The goal of this master's degree is to define parameters of double-layered model of soil (conductivity and thickness of individual layers of soil). Two models were used, numerical and real. Numerical model was constructed through method of final elements. Real model is presented by measurements of potentials on surface and in depth of test range. Results of measurements in depth of test range mostly enable accurate determination of parameters of multilayered models of soil (double and more layered). Determination or calculation of parameters of multilayered model of soil was performed through optimizing algorithm of differential evolution by achieving the lowest divergence of potentials between both models (between numerical model and measurements).
Keywords:model of soil, soil resistivity, earthing stick, numerical calculation, optimization
