Abstract
Fotonaponska elektrana snage 120 kW predstavlja sustav koji koristi sunčevu energiju za proizvodnju električne energije. Elektrana je povezana na elektroenergetsku mrežu kako bi se koristila za vlastitu potrošnju. Kako bi se osigurala sigurnost elektroenergetskog sustava, implementirana je relejna zaštita. Relejna zaštita, specifično SIEMENS 7SJ 531, VN osigurač VV 40 A i Legrand: DPX3 160, igraju ključnu ulogu u održavanju stabilnosti ove elektroenergetske mreže. Ovi uređaji detektiraju nepravilnost u sustavu, kao što su kratki spojevi, i aktiviraju prekidače kako bi izolirali problematično područje i spriječili štetu na opremi. Kako bi se proučili utjecaji fotonaponske elektrane na elektroenergetsku mrežu, provedene su analize u programu DIgSILENT PowerFactory. Ove analize obuhvaćale su strujno-naponske prilike i utjecaj elektrane na kvalitetu mrežnog napona. Također su simulirani trofazni kratki spojevi kako bi se testirala funkcionalnost i učinkovitost zaštite.
Abstract (english)
A 120 kW photovoltaic power plant represents a system that harnesses solar energy to generate electrical power. The plant is connected to the electric power grid for self-consumption purposes. To ensure the safety and stability of the electric power system, relay protection has been implemented. Specifically, SIEMENS 7SJ 531, VN fuse VV 40 A, and Legrand: DPX3 160 play a crucial role in maintaining the stability of this electrical network. These devices detect irregularities in the system, such as short circuits, and activate switches to isolate the problematic area and prevent equipment damage. To assess the impacts of the photovoltaic power plant on the electric power grid, analyses were conducted using the DIgSILENT PowerFactory software. These analyses encompassed current-voltage conditions and the influence of the plant on the quality of grid voltage. Additionally, three-phase short circuits were simulated to test the functionality and effectiveness of the protection measures.
