Abstract:Diplomsko delo obravnava delovanje transformatorjev s poudarkom na analizi izgub predvsem pri nesimetrični obremenitvi večfaznega transformatorja. Podane so osnovne elektro-fizikalne značilnosti delovanja transformatorja in različne vrste izgub v transformatorjih, ki nastanejo pri njihovem delovanju. V diplomskem delu so obravnavane tudi asimetrična obremenitev večfaznega transformatorja ter z njo povezane izgube. Predstavljeni so modeli idealnega in realnega enofaznega transformatorja, vključno z njihovimi lastnostmi in razlikami. Obravnavani so tudi trifazni transformatorski sistemi, njihove osnovne značilnosti in vezave s poudarkom na analizi izgub v železu, navitjih in dodatnih izgubah ter njihovem vplivu na delovanje transformatorjev. Za simulacijo in grafično predstavitev delovanja trifaznega transformatorja so v diplomskem delu uporabljena simulacijska orodja Matlab in Simulink.

Title:Identifying losses in transformers due to asymmetric phase loads
Abstract:The thesis deals with the operation of transformers with an emphasis on the analysis of losses, primarily under asymmetric loading conditions in a multi-phase transformer. It provides the basic electro-physical characteristics of transformer operation and various types of losses that occur during their operation. The thesis also addresses the asymmetric loading of multi-phase transformers and the losses associated with it. Models of ideal and real single-phase transformers are presented, including their properties and differences. Three-phase transformer systems are also discussed, with their basic characteristics and connections, focusing on the analysis of losses in the iron core, windings, and additional losses, and their impact on the operation of transformers. Simulation tools Matlab and Simulink are used in the thesis for simulating and graphically representing the operation of a three-phase transformer.
Keywords:transformer, load, asimmetry, losses, effciency
