Simulink transformer models based on equivalent circuits
 Petrič, Peter ; Huták, Petr (referee) ; Pazdera, Ivo (advisor)
The aim of the bachelor‘s thesis is to project and then realize models of transformer in Matlab/Simulink program. These proposed procedures show the relation between original transformer and its spare connections. The first part of bachelor‘s thesis is oriented to theory of transformers which defines basic parametres and relations between them in transformer. Later in this part we try to describe cross-over from basic transformer model to the spare connection which is needed in realization of model in Simulink. The second part of bachelor‘;s thesis is oriented to theoretical description of vector transformation. It describes some basic relations of general transformation, currents transformation and voltage in certain connections. The third part of bachelor‘s thesis shows some practical realization of spare connection models of basic transformer in Simulink program. In this part we modeled some current transformer models and voltage for single-phase and three-phase system. As to compare we have created process of currents and voltages in transformer as well as power and load of each model.
