Umeščanje hidroenergetskega objekta v prostor

Kristan, Urban (avtor), Steinman, Franc (mentor), Rak, Gašper (komentor)

Pri umeščanju malih hidroelektrarn (v nadaljevanju mHE) v prostor se srečujemo na eni strani z zakonodajo, ki spodbuja gradnjo objektov, katerih namen je proizvodnja električne energije iz obnovljivih virov in na drugi strani z zakonodajo o ohranjanju vodnih virov, ki gradnjo zavira. Diplomsko delo obravnava ustreznost lokacije, že obstoječe male hidroelektrarne, kjer preverja najpomembnejša parametra, ki vplivata na proizvodnjo in z njo povezan dobiček. To sta režim in izdatnost vodotoka skozi celo leto ter bruto višinska razlika zgornje vode za jezom in spodnje vode v sesalni komori. Ob tem upošteva trenutno zakonodajo, prostorske omejitve in okoljski vidik. Ker na obravnavanem vodotoku ni objekta, ki bi omogočal neprekinjene meritve nivoja vode, je krivulja trajanja pretokov izdelana na podlagi dnevnih podatkov obratovanja mHE in znanih ostalih parametrov v enačbi za izračun moči. Visoke vode so bile določene preko meritev in opazovanj skozi leto s pomočjo izdelane pretočne krivulje. S programsko opremo HEC-RAS in z vnesenim modelom struge ter modelom, ki posnema sistem MHE, je ob različnih pretokih bil preverjen vpliv nihanja zgornje in spodnje vode na bruto padec. Ob danih pogojih višinske razlike in pretoka je bila izbrana vrsta in velikost požiralnosti turbine po sistemu maksimalno izkoriščenih danosti in minimalnih izgub.

When locating the small hydropower plants into a certain area, we are facing the legislation that on one hand promotes the construction of facilities, whose purpose is the generation of electricity from renewable sources and on the other hand the legislation on the protection of water resources, habitats etc., which inhibits the building. The thesis deals with the appropriateness of the location of already existing small hydro power plant, which verifies the most important parameters influencing the production and the related profit. These are the run-off regime and the rate of flow of the stream throughout the year and the gross height difference between level of upstream water behind the dam and level of downstream water in the suction chamber. All this is covered by the current legislation, the spatial limits and environmental aspects. There aren't any facilities on the stream that would allow continuous measurements of water level; therefore the flow duration curve is constructed on the basis of daily data operating small hydropower plant. High waters were determined through measurements and observations throughout the year by using the designed stage-discharge curve. By entering the channel model and a model that simulates a system of small hydropower plant in the software HEC-RAS, was tested the impact of fluctuations in upper and lower waters of the gross height difference at different flow rates. At the given conditions of altitude and discharges the type and size of the turbine system was selected for maximum utilization of resources and minimal losses on the system.
