| 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. |

| Parallel abstract (English) | 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. |
