20.500.12556/DKUM-62062 VPLIV NIHANJA OMREŽNE NAPETOSTI NA DELOVANJE MALIH HIDROELEKTRARN IMPACT OF NETWORK VOLTAGE OSCILLACTION IN THE SMALL HYDRO POWER PLANTS OPERATION V diplomskem delu smo predstavili ključne elemente male hidroelektrarne in njihova delovanja. Za predstavitev rezultatov meritev smo uporabili asinhronski generator, ki je za gradnjo MHE primeren. Izbrani motor smo preračunali s pomočjo programskega paketa emLook, ter predstavili primerjavo rezultatov z nazivnimi vrednostmi. V nadaljevanju smo se osredotočili na meritev obremenitev asinhronskega generatorja, ter primerjavo rezultatov z obremenitvijo s kompenzacijo. Izmerili smo asinhronski generator v otočnem obratovanju pri različnih kapacitivnostih, ki smo jih spreminjali v okolici nazivne vrednosti kondenzatorjev. Pri tej meritev smo še opravili meritev prostega teka. Kot zadnjo meritev smo predstavili izklop pogona in bremena na omrežju. Below we present the key elements of the small hydroelectric power plants and their operation. For the presentation of the results of the measurements we used asynchronous generator, which is for the construction of SHP most suitable. Selected engine was calculated using a software package emLook, and a comparison of the results with the nominal values. Below we focus on the measurement of load induction generator, and compare the results with a load with compensation. We measured the induction generator in an island mode with different capacitances, we change up and down from the selected or calculated value capacitors. In this measurement, we have conducted measurements idling. As a final measurements are presented off actuator and the load on the network. vodne turbine asinhronski generator male hidroelektrarne nihanje omrežne napetosti water turbine induction generator small hydro power variation of the mains voltage true true false S.
