Primerjalna analiza tehnologij izdelave lopat Kaplan vodilnika v kontekstu vodenja projektov: Vpliv na stroške, življenjsko dobo in tveganja v hidroenergetiki

Kogoj, Jakob (author), Rihar, Lidija (mentor)

Diplomska naloga obravnava primerjalno analizo tehnologij izdelave lopat Kaplanovega vodilnika v hidroenergetiki. Ključni problem je izbira med kovanjem, ulivanjem in varjenjem, pri čemer se upoštevajo stroški, življenjska doba in operativna tveganja. Metodološko je raziskava temeljila na stroškovni analizi, oceni življenjske dobe in identifikaciji tveganj za vsako tehnologijo. Rezultati kažejo, da tehnologija kovanja prinaša višje začetne stroške, a dolgoročno podaljšuje življenjsko dobo in zmanjšuje tveganja za okvare. Nasprotno sta ulivanje in varjenje cenovno ugodnejši, a povezani z večjim tveganjem za napake v obratovanju.

• Title: Comparative analysis of manufacturing technologies for guide vanes of Kaplan turbines in the context of project management: effects on costs, service life and risks in hydropower generation

Abstract

The thesis presents a comparative analysis of manufacturing technologies for Kaplan guide vanes in hydropower. The main issue is the selection between forging, casting, and welding, considering costs, lifespan, and operational risks. The research methodology is based on cost analysis, lifespan evaluation, and risk identification for each technology. The results show that forging technology incurs higher initial costs but extends the lifespan and reduces the risks of failure in the long term. Conversely, casting and welding are more cost-effective but come with higher risks of operational errors.
