Prenova transformatorske postaje Galjevica krajevna skupnost

Kraševec, Tadej (author), Pantoš, Miloš (mentor), Bogovič, Jerneja (comentor)

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.

Abstract

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.
