Abstract
U ovome diplomskom radu se simuliralo što će se dogoditi sa tokovima snaga kada doĎe do uključenja DP Bogićevci na srednjonaponsku mrežu Nove Gradiške. Simulacija se radila u DigSilent PowerFactory programu. Radilo se na dva slučaja, kada smo imali maksimalnu potrošnju i minimalnu potrošnju. Uz ta dva slučaja još smo imali osnovno i rezervno napajanje kako bi zadovoljili n-1 kriterij. Računali smo tokove snaga, bilježili i usporeĎivali gubitke prije i poslije uključenja elektrane u mrežu. TakoĎer su se računali i struje i snage kratkog spoja, u istom smislu kao i za tokove, prije i poslije uključenja elektrane .Za zaključak možemo reći da je mreža zadovoljila uvjete rada, iako se na rezervnom napajanju napon na pojedinim sabirnicama znao spustiti veoma blizu granice od 0,9 p.u.. Struje kratkog spoja su porasle kako smo uključili elektranu, struja i snaga je bila veća na osnovnom napajanju nego na rezervnom zbog manje elemenata u mreži izmeĎu elektrane i nadomjesne mreže.
Abstract (english)
In this graduation thesis it was simulated what will happen to the power flows when power station Bogićevci was connected onto middle-volatge network of Nova Gradiška. The simulation is done in DigSilent PowerFactory program. There were two cases when we had maximum consumption and minimal consumption. Alongside with these two cases we had main and backup power feed because we need to meet the n-1 criterion. We compiled power flows, recorded and compared the losses before and after the power plant was plugged into the grid. Also, currents and short-circuit power were computed in the same sense as for the flows before and after powering up the power plant. For this conclusion, we can say that the grid has met the conditions of operation, although on the backup power feed the voltage at certain busbars could drop very close to the boundary of 0.9 p.u. Short circuit current increased as we switched on the power plant, currnet and power were higher on main power feed than on backup power feed because of the smaller network elements between the power station and network feed.
