Abstract
Način uzemljenja neutralne točke mreže veoma je važan za pogon mreže. Postoji mnogo načina uzemljenja koji se danas koriste u praksi, a odluka o načinu uzemljenja neutralne točke ovisi o situaciji u mreži priključenoj na transformatorsku stanicu. Pri donošenju odluke o načinu uzemljenja neutralne točke potrebno je dobro razmotriti sve prednosti i nedostatke pojedinih načina uzemljenja neutralne točke te odabrati tehnički i ekonomski najbolje rješenje. U ovome diplomskom radu analizirani su načini uzemljenja srednjenaponske mreže s obzirom na praksu u Hrvatskoj elektroprivredi, odnosno izolirano zvjezdište, maloohmsko uzemljenje, djelomična kompenzacija te rezonantno uzemljenje. Opisana je i upotreba shunt prekidača. Opisana je zemljospojna zaštita mreže ovisno o načinu uzemljenja i dan kratak pregled prakse načina uzemljenja u Europi i Hrvatskoj.
Abstract (english)
The method used for neutral point grounding is very important for power network operation. There are many ways of grounding, which are used in practice, and the decision on the method of neutral grounding depends on the situation in the network connected to the substation. When deciding on the method of neutral grounding it is necessary to thoroughly consider all the advantages and disadvantages of individual modes of neutral grounding, and then choose the best technical and economical solution. This final paper analyzes the ways of neutral point grounding in medium voltage networks used in the current practice of ''Hrvatska elektroprivreda'' which are isolated neutral point, low resistance earthing, partial compensation and resonant earthing. The use of shunt circuit-breaker is also described. The paper describes the earth-fault protection of the network, depending on the method of neutral point earthing, and gives a short overview of the earthing methods in Europe and Croatia.
