Model of solar power plant for analysis of power system transients

U ovom radu obrađeni su problemi vezani uz prijelazne pojave u elektroenergetskom sustavu na primjeru mreže s priključenom solarnom elektranom. Gotov model solarne elektrane, s priključnom mrežom i pripadnim elementima, koji je konstruiran u programu za proračun prijelaznih elektromagnetskih pojava EMTP-RV, detaljno je opisan te su provedene simulacije utjecaja prijelaznih pojava na mrežu. Također, opisane su glavne karakteristike solarne ćelije te ovisnosti njezine I-U karakteristike o raznim parametrima (temperatura, ozračenje, paralelni i serijski otpor…).This graduation thesis analyzed the problems associated with power system transients in the case of power grid with connected solar power plant. Finished model of a solar power plant, with connection power grid and associated elements, which was constructed in the software for power system transients EMTP-RV, has been described in detail along with the implementation of simulations regarding impact of power system transients on the power grid. Main characteristics of solar cell and dependence of its I-U characteristics on various parameters (temperature, irradiation, parallel and serial resistance ...) have also been described
