Complete design of protection for solar power plants according to standard SIST EN 62548

V diplomskem delu so predstavljene vse komponente male sončne elektrarne in njihovo delovanje. Nato sta predstavljena zaščita, primerna za uporabo pri sončnih elektrarnah, ter njeno delovanje. Predstavljena zaščita je tokovna, prenapetostna in poleg zaščite so prikazani tudi ozemljitveni sistemi. Sledi standard SIST EN 62548, ki obsega 44 strani in ponuja celovit pristop k načrtovanju fotonapetostnih polj. Standard obravnava vse naprave, elemente in načrtovanje nosilne konstrukcije. Po obdelanem standardu, pri čemer je bil poudarek na DC stran fotonapetostnega sistema, je podan predlog lastnega projekta, torej izbira elementov sončne elektrarne, kot tudi vsa zaščita, ki sledi zahtevam standarda.In the bachelor’s thesis, all components of a small solar plant are presented, as well as their operations. Protection suitable for the use in solar power plants is then presented, as well as its operation. Overcurrent protection, overvoltage protection are introduced, as well as earthing systems. This is followed by the SIST EN 62548 standard, which comprises 44 pages and offers a complete approach to the design of the photovoltaic system. The standard handles all devices, elements, and the design of the support structure. According to the shown standard, with an emphasis on the DC side of the photovoltaic system, a proposal of my project was made, thus the choice of elements of the solar power plant, as well as all the protection that follows the requirements of the standard
