Abstract:Magistrsko delo obravnava matematično modeliranje trifaznega energetskega transformatorja z diferencialnimi enačbami s skoncentriranimi parametri. Cilj naloge je bil izpeljava in programska implementacija matematičnega modela, ki upošteva nelinearne lastnosti magnetnega jedra. Namenjen je analizi stacionarnega obratovanja in prehodnih pojavov. Model je bil implementiran v odprtokodnem programskem jeziku Python in validiran z uporabo programskega orodja DIgSILENT PowerFactory ter z meritvami na laboratorijskem transformatorju. Rezultati potrjujejo delovanje in uporabnost modela za stacionarne in dinamične simulacije energetskih transformatorjev, ki opisujejo delovanje transformatorja, hkrati pa razkrivajo omejitve pri upoštevanju nelinearnosti magnetnega jedra ter nakazujejo možnosti za nadaljnji razvoj.

Title:Derivation, software implementation and experimental validation of mathematical model of a power transformer
Abstract:This master’s thesis focuses on the mathematical modelling of a three-phase power transformer using a lumped-parameter model in the form of nonlinear ordinary differential equations. The objective of the thesis is the derivation and software implementation of a mathematical model that accounts for the nonlinear properties of the magnetic core. The model is intended for the analysis of steady-state operation and transient phenomena. It was implemented in the open-source programming language Python and validated using the DIgSILENT PowerFactory software as well as measurements on a laboratory transformer. The results confirm the performance and applicability of the implemented model for steady-state and dynamic simulations describing transformer behavior, while also revealing limitations in the consideration of core nonlinearities and suggesting possibilities for further development.
Keywords:three-phase transformer, mathematical modelling, inrush phenomenon
