Abstract

U ovom radu opisana je teorija električnih strojeva i njihove nadomjesne sheme. Koristeći programski paket NEPLAN napravljene su simulacije u kojima je analiziran statički i dinamički utjecaj male asinkrone hidroelektrane na elektroenergetsku mrežu. Razmatran je utjecaj elektrane na iznose napona čvorišta, struje kratkih spojeva, gubitke u mrežu, MTU signal te kvalitetu električne energije te su dobivene vrijednosti uspoređene s normom HRN EN 50160. Također, napravljena je frekvencijska analiza utjecaja kompenzacije elektrane. Dana je i usporedba mjerenja kvalitete električne energije prije i nakon priključenja elektrane. Moguće je zaključiti da ova elektrana ispunjava sve potrebne zahtjeve za priključenje na elektroenergetsku mrežu.

Abstract (english)

In this paper electrial machines theory and their equivalent circuits are described. The simulations are carried out using NEPLAN programming package and static and dynamic impacts of a small asynchronous hydro generator on electrical grid are analysed. Impacts on nodes voltage level, short circuit currents, losses in power transmission, ripple control signal and power quality parameters are calculated and the results are evaluated and compared with standard HRN EN 50160. This paper also brings the frequency analysis of capacitor bank impact. Measurements of power quality parameters before and after grid connection are presented and compared. The conclusion of this paper is that given power generator has all the requirements needed for electric grid connection.
