Abstract
U ovom diplomskom radu opisana je simulacija postojeće fotonaponske elektrane 153 kW s pripadajućom distributivnom mrežom pomoću programskog paketa „EasyPower“, verzija 9.0.4. Izvršeni su tokovi snaga za minimalno i maksimalno opterećenje i provjerena postotna odstupanja napona od nazivne vrijednosti za navedene scenarije. Proveenim frekvencijskim odzivom provjereno je pri kojoj frekvenciji postoji mogućnost nastanka rezonancije sa signalom mrežnog tonfrekventnog upravljanja. Nadalje, opisani su kratki spojevi i osnovni zahtjevi postavljeni pred zaštitu. Vrijednosti jednofaznih i trofaznih kratkih spojeva ispitane su za razna mjesta u simuliranoj mreži radi parametriranja nadstrujne, odnosno zemljospojne zaštite. Grafičkim prikazom iznosa kratkih spojeva na strujno - vremenskim karakteristikama na raznim mjestima u mreži (sabirnicama) provjereno je jesu li zadovoljeni osnovni zahtjevi postavljeni pred parametriranu zaštitu. Kao rezultat, dan je prijedlog moguće koordinacije zaštite fotonaponske elektrane istih ili sličnih karakteristika.
Abstract (english)
By using the software package „EasyPower“, version 9.0.4. simulation of photovoltaic power plant 153 kW with its related distributive network is done and presented in this paper. Load flows were executed for the minimal and the maximal loads and the nominal voltage deviations in percentage were examined for the both scenarios. Frequency scan was done to check the possibility of generating the resonance with the ripple control signal. Furthermore, short circuits and basic protection requirements are described. Values in case of single-line-to-ground fault and three-phase fault at the various locations in the simulated network were examined due to setting the parameters for the overcurrent protection and the ground fault protection as well. By graphically presenting the fault values on time – current characteristics at the various locations (busses) in the simulated network were examined if the basic protection requirements are satisfied. As the result of this simulation, a suggestion for possible coordination of the numerical protection of the same or similar type of photovoltaic power plant is made
