20.500.12556/RUL-187256 Prenova transformatorske postaje Galjevica krajevna skupnost Reconstruction of the Galjevica krajevna skupnost Transformer Substation Tema diplomskega dela je predelava oziroma rekonstrukcija transformatorske postaje na območju distribucijskega podjetja Elektro Ljubljana. V sklopu predelave je predvidena zamenjava celotne opreme znotraj postaje, ki obsega nizkonapetostni stikalni blok, srednjenapetostni stikalni blok ter transformator. V delu bodo opisane stare ter nove komponente ter njihove zaščitne naprave in predstavljeni načrti obstoječih ter predvidenih oziroma novih stanj v postaji. Diplomsko delo vsebuje splošen opis zaščite ter opise zaščitnih naprav, ki so ključnega pomena za varno delovanje transformatorske postaje ter za varno delovanje elektroenergetskega omrežja pred transformatorsko postajo in po njej. Na koncu sledi še simulacija kratkega stika v omrežju. Ob zamenjavi opreme lahko potrdimo, da je nova oprema zanesljivejša ter varnejša za uporabo v primerjavi s staro. The topic of the diploma thesis is the refurbishment and reconstruction of a transformer substation within the distribution network of Elektro Ljubljana. As part of the reconstruction, the complete replacement of the substation equipment is planned, including the low-voltage switchgear, medium-voltage switchgear and transformer. The thesis presents both the existing and the newly installed components, together with a description of their protective devices. It also includes drawings of the existing substation layout and the proposed new configuration. In addition, the thesis provides a general overview of power system protection and describes the protective devices that are essential for the safe operation of the transformer substation and the reliable protection of the electrical power system both upstream and downstream of the substation. Finally, a short-circuit simulation of the electrical network is performed. Based on the replacement of the equipment, it can be concluded that the new equipment provides higher reliability and a greater level of operational safety compared to the existing equipment. transformator zaščita SN stikalni blok NN stikalni blok simulacija transformer protective devices medium-voltage switchgear low-voltage switchgear simulation true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-09 13:20:10 2026-09-09 13:20:12 2026-09-21 11:25:28 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 63435 291781379 Krasevec_Tadej_-_Prenova_transformatorske_postaje_Galjevica_krajevna_skupnost.pdf Krasevec_Tadej_-_Prenova_transformatorske_postaje_Galjevica_krajevna_skupnost.pdf 1 BC6F2664D956593C1CFAC080B5201B78 98f7622b343225ac14750da8895ee4afde801c66f0201b2d9d4c959a9545ad24 669f0a9a-ac40-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246794 Fakulteta za elektrotehniko 0 0 0
