Abstract [en]

This project aimed at dimensioning a twin-blade Savonius turbine for the neutrino research project ARIANNA, based in Antarctica. ARIANNA uses RF-sensor stations equipped with solar cells and a storage battery. During winter, insufficient solar irradiance reduces the station's live-time. The goal of the turbine was to provide a live-time of 80 % during this time of year. The generator as well as regulation controller was built to suit the battery and its Battery management unit. Simulations based on wind-speed data were done to determine the blade size required to achieve the desired live-time. Based on early simulations a Savonius turbine was built, of approximate size, to empirically examine it's coefficient of performance in different wind speeds. The results of the project is a proof of concept (POC) turbine as well as simulation modells capable of describing the different aspects of the machine. As the POC turbine did not quite produce satisfying power, sources of errors were identified from which a first prototype can be built.
