Abstract
V Sloveniji predstavlja hidroenergija pomemben delež pri zagotavljanju oskrbe z električno energijo pridobljeno iz obnovljivih virov (OVE). Večino te energije pridobimo v hidroelektrarnah na večjih slovenskih vodotokih, del proizvodnje pa odpade na manjše enote ali tako imenovane male hidroelektrarne (mHE). Možnosti za pridobivanje električne energije iz malih hidroelektrarn je na naših vodotokih veliko. Eden takih vodotokov z velikim hidroenergetskim potencialom je tudi reka Kokra. V diplomski nalogi je bila obravnavana možnost idroenergetske rabe na izbranem odseku reke Kokre.S programskim orodjem SMART Mini – Idro je bila opravljena analiza proizvodnje električne energije. Pri tem sta obravnavani dve izvedbeni možnosti mHE glede na dolžino odvzema in s tem pogojeno razpoložljivo količino vode. Prva izvedbena možnost obravnava energetsko rabo celotnega odseka z eno mHE z dolgim odvzemom vode. V drugem primeru pa je bilo analizirano izkoriščanje odseka z več mHE s kratkim odvzemom vode. S pomočjo prostorskih podatkov in dolžino odvzema so bile določene lokacije posameznih mHE. Za vsako odvzemno mesto je bila glede na velikost prispevne površine in velikosti ekološko sprejemljivega pretoka izračunana razpoložljiva količina vode. Na koncu je opravljena primerjalna analiza proizvodnje električne energije obeh izvedbenih možnosti.

Title:Comparative analysis of the energy exploitation potential of the Kokra river section
Abstract:
Exploitation of hydropower energy in Slovenia represents a significant share in securing the power supply, produced from renewable energy sources (RES). Most of this energy is obtained by hydropower plants in the major Slovenian rivers, but part of production goes to smaller units, or so-called small hydropower plants (SHPs). Many river in Slovenia are appropriate for SHPs. One of these, with high hydropower potential, is Kokra. In the present work options of hydropower uses on the selected section of the river Kokra are described. SMART Mini-Idro program was used to analyze the production of electric energy. Two implementation options of SHPs are presented, considering the penstock, together with the available amount of water. First implementation option addresses the energy use of the entire section, using one SHP with long penstock.Use of multiple SHPs with short penstock is given in the second implementation option. Spatial data and considered penstock length were used to determine the locations of SHPs. Considering the size of the catchments and ecologically acceptable flow, available amount of water for each sampling site was calculated. A comparative analysis of both options is also given.
