Abstract

Porastom cijena u svim gospodarskim granama pa tako i u energetici, sve više tvrtki se odlučuje na postavljanje fotonaponskih panela na krovovima objekata ili čak na slobodnom prostoru oko objekta. Time se smanjuju računi za električnu energiju, a neke tvrtke koje imaju manju potrošnju energije nego proizvodnju, višak predaju u mrežu. U većini slučajeva se radi o složenom priključku jer su elektrane većih snaga, pa treba razmotriti stanje u mreži nakon priključenja fotonaponske elektrane. Također treba i izračunati struje kratkih spojeva koje se mogu pojaviti u mreži te prema tim analizama pravilno dimenzionirati opremu za priključenje.

U radu je analiziran način priključenja fotonaponske elektrane na 110 kV prijenosnu mrežu.

Abstract (english)

With the rise in prices in all economic sectors, including energy, more and more companies are deciding to install photovoltaic panels on the roofs of buildings or even in the free space around the building. This reduces electricity bills, and some companies that have less energy consumed than produced deliver more to the grid. In most cases, it is a complex connection because the power plants are of higher power, so the situation in the network after the connection of the photovoltaic power plant should be considered. It is also necessary to calculate the short-circuit currents that can occur in the grid and, according to these analyses, correctly dimension the equipment for connection.

This paper will analyze the method of connecting the photovoltaic power plant to the 110 kV transmission grid.
