| Abstract | Kvaliteta električne energije u nekom dijelu mreže se određuje mjerenjem relevantnih
elektromagnetskih parametara i uspoređivanjem istih s važećim normama, a za nju su
odgovorni i operator sustava i korisnici mreže. Pri analizi kvalitete električne energije se
najčešće promatraju naponski propadi i prekidi, naponska kolebanja, povremeni i tranzijentni
previsoki naponi, harmonici i međuharmonici, nesimetričnost napona, promjene osnovne
frekvencije mreže te prisutnost signalnih napona. Osnovne komponente FN elektrane izravno
priključene na mrežu su fotonaponski moduli, izmjenjivač (pretvara istosmjernu struju u
izmjeničnu) i brojilo predane električne energije. Sa stajališta kvalitete električne energije je
najznačajniji izmjenjivač. Analiza utjecaja fotonaponskog sustava na kvalitetu električne
energije u elektroenergetskom sustavu na mjestu priključka se provodi mjerenjem vrijednosti
pokazatelja kvalitete prije i nakon priključenja. Dobiveni rezultati se uspoređuju međusobno i
sa zahtjevima norme EN 50160 i Mrežnih pravila |

| Parallel abstract (English) | Power quality in any part of the network can be determined by measuring the relevant
electromagnetic parameters and comparing them with valid standards. Utility and end – users
are both responsible for power quality. Analysis of power quality usually considers voltage
dips and interruptions, voltage variations, voltage swells and overvoltages, harmonics and
interharmonics, voltage unbalance, power frequency variations and the presence of signal
voltages. Basic components of grid-connected photovoltaic power plant are photovoltaic
modules, inverter (concerts DC power to AC) and electric meter. From the standpoint of
power quality the most important part is inverter. Analysis of power quality impact of gridconnected
photovoltaic system at the connection point can be determined by measuring values
of quality indicators before and after connection to the grid. The results are compared to each
other and with requirements of EN 50160 and grid code |
