Abstract
Vjetroagregati zbog svoje visoke konstrukcije postaju sve izloženiji udarima munje. Iz tog razloga potrebno je detaljno modelirati prenaponsku zaštitu vjetroagregata, jer udari munje mogu proizvesti velike štete na komponentama vjetroagregata. U ovom je radu modeliran sustav vjetroagregata pri udaru munje u lopatice. Za dobivanje što detaljnijih rezultata simulacije potrebno je poznavati podatke komponenti sustava vjetroagregata. Simulacijom navedenog sustava opisane su naponske i strujne prilike na uzemljivaču, stupu, transformatorima, generatoru, lopaticama i odvodnicima prenapona prilikom atmosferskog pražnjenja u lopatice vjetroagregata. U nekim simulacijama su korištene različite vrijednosti struje udara munje (100 kA, 50 kA, 20 kA) i otpora uzemljivača R (10 Ω, 5 Ω, 1 Ω) kako bi se opisale naponske i strujne prilike na komponentama sustava pri promjenjivim vrijednostima otpora uzemljivača i struje udara munje.
Abstract (english)
Due to their high construction, wind turbines are becoming more and more exposed to lightning strikes. For this reason, it is necessary to model the surge protection of wind turbines in detail. Because lightning strikes can produce great damage to wind turbine components. In this paper, the wind turbine system is modeled when lightning strikes the blades. To obtain the most detailed simulation results, it is necessary to know the data of the components of the wind turbine system. The simulation of the mentioned system describes the voltage and current conditions on the earthing switch, pole, transformers, generator, blades, tower and surge arrester during atmospheric discharge into the blades of wind turbines. In some simulations, different values of lightning current (100 kA, 50 kA, 25 kA) and earthing resistance R (10 Ω, 5 Ω, 1 Ω) were used to describe the voltage and current conditions on the system components at variable earthing resistance values and lightning strikes.
