20.500.12556/RUL-180112 Doinstalacija HE Medvode v sklopu verige hidroelektrarn na srednji Savi magistrsko delo Uprating of the Medvode HPP within the hydropower chain on the middle Sava River Magistrsko delo obravnava tehnično, energetsko in ekonomsko upravičenost doinstalacije hidroelektrarne Medvode z izvedbo derivacijskega sistema, katerega cilj je povečanje instaliranega pretoka s 150 m³/s na 260 m³/s ter omogočanje vzpostavitve sklenjene hidroenergetske verige na reki Savi med HE Mavčiče in HE Medvode. Razvita sta bila numerični model obratovanja v urnem časovnem koraku ter hidravlični model za dimenzioniranje ključnih objektov. Raziskava vključuje tudi izdelavo tehničnih načrtov derivacijskega sistema, ki potrjujejo prostorsko in gradbeno izvedljivost predlagane rešitve, analiza pa je bila dopolnjena z ekonomsko optimizacijo na podlagi tržnih podatkov za različne scenarije cen električne energije. Rezultati so pokazali, da je obstoječe obratovanje elektrarne omejeno zaradi vodnogospodarskih režimov, kar povzroča prelivanje in zmanjšano proizvodnjo. Z doinstalacijo se povprečna letna proizvodnja poveča z 78,4 GWh na 139,5 GWh, delež prelite vode pa se zmanjša z 9,31 % na 3,29 %. Nova konfiguracija omogoča prehod na vršni režim obratovanja, kar vodi do višjih prihodkov; v najugodnejšem scenariju znaša letni prihodek 17,7 milijona evrov. S tem je potrjena tehnična izvedljivost, energetska učinkovitost in ekonomska smotrnost predlagane rešitve. Raziskava predstavlja pomemben prispevek k razvoju metodologije načrtovanja hidroenergetskih objektov, saj razviti modeli in tehnični načrti tvorijo podlago za nadaljnje faze projektiranja in umeščanja v prostor. Rezultati neposredno podpirajo cilje slovenskega Nacionalnega energetskega in podnebnega načrta ter evropskih strategij prehoda v nizkoogljično družbo, doinstalacija hidroelektrarne Medvode pa predstavlja strateški korak k povečanju energetske neodvisnosti, prožnosti elektroenergetskega sistema in učinkovitejši izrabi vodnega potenciala Save. This master's thesis examines the technical, energy-related, and economic feasibility of upgrading the Medvode hydropower plant by implementing a derivation system that increases the installed discharge from 150 m³/s to 260 m³/s. This uprating enables the establishment of a continuous hydropower chain on the Sava River between Mavčiče HPP and Medvode HPP. To support the analysis, a proprietary hourly operational model and a hydraulic model for the dimensioning of key structures were developed. The research further includes the preparation of technical design documentation confirming the spatial and construction feasibility of the proposed solution, and is complemented by an economic optimization based on electricity market price scenarios. The results indicate that the current operation of the power plant is constrained by water management limitations, leading to significant spillage and reduced energy production. Following the proposed uprating, the average annual generation is projected to increase from 78.4 GWh to 139.5 GWh, while the proportion of spilled water is reduced from 9.31% to 3.29%. The new configuration enables the power plant to operate in peak mode, substantially increasing energy market revenues, with the most favorable scenario yielding an annual income of EUR 17.7 million. These results confirm the technical feasibility, energy efficiency, and economic viability of the proposed solution. The research makes a significant contribution to the field of hydropower engineering through the development of advanced numerical models and technical designs that support future project development and spatial planning. The findings directly support the strategic objectives of the Slovenian National Energy and Climate Plan and the European transition to a low-carbon energy system, demonstrating that the uprating of Medvode HPP represents a key step towards enhancing energy flexibility, self-sufficiency, and the sustainable utilization of renewable water resources. magistrska dela hidroelektrarna Medvode doinstalacija numerični model obratovanja projektiranje Sava master thesis HPP Medvode uprating numerical operational model engineering design Sava River true false false [P.
