Abstract

U današnje vrijeme, zbog onečišćenja okoliša i utjecaja na klimu, svijet se
sve više okreće obnovljivim izvorima energije. Najveći porast očituje se u vjetroelektranama
i fotonaponskim elektranama. Međutim, takve elektrane imaju i
nedostataka. One su nepredvidive te je njihova proizvodnja promjenjiva. Time
utječu na stabilnost elektroenergetskog sustava. Stoga je prilikom njihove integracije
potrebno posvetiti pažnju zagušenjima u mreži u osnovnom uklopnom
stanje te prilikom ispada jednog od elemenata mreže.
U ovom radu analizirala se integracije buduće vjetroelektrane snage 60 MW koja
se planira izgraditi na području Bosne i Hercegovne. Provedeni su proračuni
tokova snage, analize sigurnosti n-1 te proračuni kratkog spoja za slučaj prije
priključenja vjetroelektrane te za pet različitih slučajeva priključenja elektrane
na postojeće 110 kV, odnosno 220 kV dalekovode. Rezultatima se pokazalo da ni
u jednom slučaju neće doći do značajnijih preopterećenja vodova.

Abstract (english)

Nowadays, due to environmental pollution and climate impact, the world
is turning to renewable energy. The largest increase is obersved in wind and
solar power plants. However, such power plants also have a lack. They are
unpredictably and their production is variable. Weather affects the stability of
power system. Therefore, before connecting them, it is necessary to pay attention
to congestion in the network in the basic switching state and when one of the
network elements turns out.
This study analyses the integration of the future 60 MW wind farm, which is
planned to be built in Bosnia & Herzegovina. Power flow calculation, n-1 analyzes
and short-circuit calculations were performed for the case before the connection
of wind farm and for five different cases of connecting the power plant to the
existing 110 kV and 220 kV transmission lines. The results showed that in no
case will there be significant overloading of lines.
