Simulation of electric machines
Klíma, Jiří ; Mišinger, Lukáš (referee) ; Mach, Martin (advisor)
This thesis deals with modeling and simulations of DC and AC machines. They were created by four mathematical models. Three models of DC motors with different type of excitation (compound, serial, derivative) and one model for asynchronous motor. All models were implemented in MATLAB & Simulink. After measuring and setting the basic parameters of the machines, simulations were running. Simulation results are then compared with measured waveforms.

Synchronous generator in island operation
Juchelka, Roman ; Huzlík, Rostislav (referee) ; Ondrůšek, Čestmír (advisor)
This thesis deals with the dynamic analysis of a synchronous generator in island operation. The analysis is based on the basis of the theory of generalized electric machine. First the mathematical description of the synchronous generator is converted from real quantities to the quantities d, q, 0 using Park's transformation. In the next part of thesis is done the analysis of voltage change dependent on the load change in MATLAB Simulink software. Universal models useful for analysis of various machines and various load changes and short-circuit faults simulation were created in this software. There is also mentioned the possibility of excitation of synchronous generator and the effect of damping winding on its operation.
