Transformer models for educational purposes
 Beran, Vojtěch ; Ctibor, Jiří (referee) ; Pazdera, Ivo (advisor)
The aim of the bachelor's thesis is to project and realize models of transformers in Matlab and Simulink program. Projected models explain the theoretical precondition of the models. The aim is also to create manuals for models usage. The theoretical part bachelor's thesis is focused on transformer theory, which defines the properties, physical quantities, parameters and relations between them. In this part is defined transition from the basic model to models of current and voltage transformer, which forms the basis for the realization of simulations in Simulink. The next part describes vector transformation needed for modeling three phase system, defining the power, voltage and current of the transformer and for change of winding connection. Last part describes non-linear magnetic field. The practical part of the bachelor's thesis is the practical implementation of transformer models in Simulink. Realized models are models of current and voltage transformers. Each model has a form of linear and non-linear model and can work in single-phase or three-phase system. The output of simulation are values and voltage, current and power waveforms for a given load. There is a brief manual for usage for each model.
