20.500.12556/DKUM-44450 DOLOČITEV OPTIMALNEGA ODPRTJA IGEL V MALI HIDROELEKTRARNI MLINCA DETERMINATION OF OPTIMUM NEEDLE VALVES OPENING IN THE SMALL HYDROPOWER PLANT MLINCA V diplomskem delu je predstavljena mala hidroelektrarna Mlinca, ki je postavljena v neposredni bližini Mojstrane in v kateri so bile opravljene meritve. Na podlagi opravljenih meritev in izračunov smo s pomočjo računalniških programov Microsoft Excel in Matlab pokazali, kako se izkoristek in moč agregata spreminjata s pretokom vode. V zaključnem delu poskušamo tudi dokazati, da z izbiro nekaterih režimov (ti določajo odprtje posameznih igel) regulacije pretoka vode skozi šobe dosežemo večjo proizvodnjo električne energije in da obraba materialov vpliva na izkoristek agregata. The thesis presents the Small Hydropower Plant Mlinca that is located in the immediate vicinity of Mojstrana and where the measurements were conducted. Based on the conducted measurements and calculations we showed with the help of computer programs Microsoft Excel and Matlab, how the efficiency and power of the generator alter with the water flow. In the final part we try to prove that we can achieve greater production of electrical energy with a selection of some regimes for the regulation of the flow of water through the nozzles (they determine the opening of individual needle valves) and that the wear of materials impacts the efficiency of the generator. mala hidroelektrarna regulacija pretoka vode optimizacija.
