Abstract
U ovom diplomskom radu analiziran je rad generatora priključenog na elektroenergetski sustav. Rad se sastoji od teorijskog i praktičnog dijela. S obzirom na važnost sinkronog generatora kao elementa elektroenergetskog sustava, u teorijskom dijelu su opisani konstrukcijski elementi generatora i dan je detaljan fizikalni i matematički opis rada generatora. Također je izvršena transformacija varijabli iz trofaznog u dvofazni koordinatni sustav čime su pojednostavljene statorske i rotorske jednadžbe. Pored toga, analizirana je kutna stabilnost generatora priključenog na EES. Nužan uvjet stabilnog stanja u mreži predstavlja održanje generatora u sinkronizmu. Praktični dio rada se izvodi u računalnom programu DigSilent 14.1. Simulirani su kratki spojevi na sabirnicama blizu i daleko od generatora, te je promatran njihov utjecaj na stabilnost generatora. Za definirane događaje snimljene su karakteristike: kuta rotora, radne snage u ovisnosti o kutu rotora, struja, napona i frekvencija generatora.

This paper analyzes the operation of generator connected to the power system. The work consists of theoretical and practical parts. Given the importance of synchronous machine as an element of the power system, the theoretical part described structural elements of generator and an overview of physical and mathematical description of generator is given. Also, transformation of variables is executed from three-phase to two-phase coordinate system which simplifies stator and rotor equations. Further, this paper analysis rotor angle stability of generator connected to the power system. Maintenance of generator in synchronism represent a necessary condition for stable operation. Practical part is performed in a computer program DigSilent 14.1. Short circuit events are simulated on the buses near and far from the generator, and observed ther impact on the stability of the generator. For defined events operation variables such as generator rotor angles, active powers, current, voltages and frequency were recorded.
