Abstract

U ovom radu opisan je princip rada vjetroagregata, postupak proračuna struja kratkog spoja u skladu s normom IEC 60909, te je modeliran dio elektroenergetske mreže Republike Hrvatske na području oko Meline. Napravljen je proračun struja kratkog spoja u programskom alatu ETAP 16.0.0. uz poseban osvrt na utjecaj vjetroelektrane Vrataruša i njezin doprinos iznosu struje kratkog spoja. VE Vrataruša modelirana je na četiri različita načina uz četiri tipa generatora kako bi se istražio utjecaj pojedinog tipa generatora u vjetroagregatu na iznos struje kratkog spoja. Modelirani tipovi generatora su: sinkroni generator, asinkroni kavezni generator, dvostruko napajani asinkroni generator (DFIG) i asinkroni generator s potpunim priključkom pomoću elektroničkih energetskih pretvarača.

Abstract (english)

In this thesis the principle of operation of wind turbines is decribed as well as short circuit calculation in accordance with the standard IEC 60909 and a part of the power grid of the Republic of Croatia in the area around Melina was modeled. A calculation of the short-circuit current was made in the software tool ETAP 16.0.0. with special reference to the impact of the Vrataruša wind farm and its contribution to the magnitude of the short circuit currents. VE Vrataruša was modeled in four different ways with four types of generators in order to analyse the influence of each type of generator in the wind turbine on the magnitude of short-circuit currents. The modeled types of generators are: synchronous generator, asynchronous cage generator, doubly fed induction generator (DFIG), and asynchronous generator with power converter through which the entire power of the generator is processed.
