20.500.12556/RUL-183945 Zanesljivost distribucijskega elektroenergetskega sistema v Sloveniji Reliability of distribution electric power system in Slovenia Diplomsko delo obravnava analizo zanesljivosti distribucijskega sistema v Sloveniji, ki predstavlja ključni element za zagotavljanje gospodarske stabilnosti in delovanje ključne infrastrukture. Namen dela je izvesti celovito oceno tehničnih kazalnikov zanesljivosti v obdobju zadnjih desetih let, ter ovrednotiti učinkovitost omrežja. Metodologija temelji na interpretaciji klasičnih kazalnikov zanesljivosti. Delo vključuje tudi primerjalno analizo med distribucijskim in prenosnim sistemom v Sloveniji, ter mednarodno primerjavo znotraj Evropske unije s sistemi na drugih celinah. Rezultati kažejo na splošno izboljšanje robustnosti sistema v normalnih obratovalnih pogojih skozi opazovana leta, vendar so te zelo odvisne od ekstremnih vremenskih pojavov, kar potrjujeta tudi dva ekstremna dogodka: žledolom leta 2014 in poplave v letu 2023. Ugotovljena je bila tudi visoka povezava zanesljivosti sistema med stopnjo pokablitve in kazalnikom prekinitve. Regionalna analiza Slovenije je razkrila specifične izzive posameznih elektrodistribucijskih podjetij, kjer na njihove rezultate močno vpliva geografska razgibanost in tip omrežja. V zaključku je izpostavljeno, da bi razvoj distribucijskih podjetij v prihodnosti moral biti usmerjen v ohranjanje zanesljivosti in v digitalizacijo. Poudarjena je nujnost nadgradnje nizkonapetostnega nivoja in povečanje investicij v ruralnih območjih. V prihodnosti je videti tudi velik izziv zelenega prehoda, kjer se odvija elektrifikacija ogrevanja ter mobilnosti. This thesis analyses the reliability of the electricity distribution system in Slovenia, which represents a key element for ensuring economic stability and the functioning of critical infrastructure. The aim of the work is to carry out a comprehensive assessment of technical reliability indicators over the last ten years and to evaluate network performance. The methodology is based on the interpretation of classical reliability indicators. The work also includes a comparative analysis between the distribution and transmission systems in Slovenia, as well as an international comparison within the European Union and with systems on other continents. The results indicate a general improvement in system robustness under normal operating conditions over the observed period, although performance is highly dependent on extreme weather events — as confirmed by two extreme events: the ice storm of 2014 and the floods of 2023. A strong correlation was identified between system resilience and the degree of cable network penetration. The regional analysis of Slovenia revealed specific challenges faced by individual electricity distribution companies, where results are strongly influenced by geographical terrain and network type. In conclusion, it is highlighted that the future development of distribution companies should be directed towards strategic resilience and digitalisation. The necessity of upgrading the low-voltage level with SCADA systems and increasing investments in rural areas is emphasised. A significant future challenge is also the green transition, where the mass electrification of heating and mobility presents both an opportunity and a strain on existing network infrastructure. zanesljivost oskrbe distribucijski sistem kazalnik SAIDI SAIFI kakovost napetosti neprekinjenost. supply reliability distribution system indicator SAIDI SAIFI power quality continuity of supply true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-06-22 15:20:00 2026-06-22 15:20:11 2026-06-23 04:01:02 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 63287 Kozar_Anze_-_Zanesljivost_distribucijskega_elektroenergetskega_sistema_v_Sloveniji.pdf Kozar_Anze_-_Zanesljivost_distribucijskega_elektroenergetskega_sistema_v_Sloveniji.pdf 1 0A342AFC439A960798C375F65E5CCBA2 5f875544f5ba6ff27a5cc05532847eb01e50124e7dbf7629d89e2390c1e0d806 06a15319-6e3d-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=236281 Fakulteta za elektrotehniko 0 0 0
