Abstract
U diplomskom radu napravljen je model stvarne mreže u programskom alatu „Easy Power“ (verzija 9.6), te je koordinirana zaštita i simuliran rad fotonaponske elektrane 500kW koja radi paralelno s postojećom mrežom HEP-a. Navedena je konfiguracija fotonaponske elektrane, te uvjeti priključenja fotonaponske elektrane Orahovica 1 na distributivnu mrežu HEPa. Izvršeni su tokovi snaga za minimalno i maksimalno opterećenje i provjerena postotna odstupanja napona od nazivne vrijednosti za navedene slučajeve. Opisani su zahtjevi zaštite i podešenje nadstrujne zaštite u fotonaponskoj elektrani i pripadnoj distributivnoj mreži. Također su opisani kratki spojevi, te je izvršena simulacija trofaznih kratkih spojeva na različitim mjestima u mreži. Na kraju je grafičkim prikazom iznosa kratkih spojeva na strujno - vremenskim karakteristikama na raznim mjestima u mreži (sabirnicama) provjereno jesu li zadovoljeni osnovni zahtjevi postavljeni pred parametriranu zaštitu.

Parallel abstract (English)
In this paper, a model of the real distribution network was made in the "Easy Power" program (version 9.6), coordination of protection and operations of the 500 kW photovoltaic power plant were simulated with the existing HEP’s distribution network, which work parallel. The configuration of the photovoltaic power plant is listed as well as the condition of connecting the photovoltaic power plant Orahovica 1 to the HEP’s distribution network. The load flows for minimum and maximum were completed and percentage voltage deviation from the nominal values for the above mentioned cases were tested. The requirements of protection, overcurrent protection setting in the photovoltaic power plant and an associated distribution network were described in the paper. Further, short circuits were described and simulations of three-phase short circuits of the different places in the network were also performed. At the end, graphically is shown the amount of short circuits on the time- current curves at various points in the network(buses) and the compliance with the basic requirements set in the parameters set before the protection is verified.
