Model of a diesel-generator
Suchomel, Vít ; Ondrůšek, Čestmír (referee) ; Bárta, Jan (advisor)
This work deals with principles and methods of drive-train regulation. Furthermore it deals with simulation of drive train via Simulink in a program Matlab. The work is done in cooperation with Siemens Drasov. A created model will be used as an educational model for employees of company. The model will allow better and more graphic education. In the beginning part is drive-train generally descripted. Next part is especially about a synchronous generator. This work also explains a working principle of generator and excitation. There is a cooperation of generator with electrical network described and transformation of synchronous generator into a model of general electric machine showed, substitute scheme is in d, q coordinates deduced in the next part. There are simulations of different states of generator solved in a practical part of the work. At first there is simulation of generator’s load change by using the created model done and further there are simulations of short circuits in stator winding realized. Finally there are simulations of connecting the synchronous generator into infinite bus for ideal and unfavorable conditions done. All simulation models include lots of oscilloscopes, which allow time courses to display, currents, shaft’s revolutions, torques and so on.
