| Summary: | A nanogrid system for supplying neutrino detectors on Antarctica with electricity is designed and built. The nanogrid system could later on be implemented in various configurations where suppling electricity to neutrino detectors is one area of use. The energy system that is acting on site in Antarctica is based around solar panels to provide power to the measuring equipment. However, providing electricity in such a way is not optimal due to its failure in delivering electricity at times. A nanogrid that can stand the demands of constant energy supply to the measurement station are therefore constructed. The energy sources that are integrated into the nanogrid are an innovation in vertical axis wind turbine and photovoltaics. The wind turbine innovation is tested under real conditions for the first time. In the constructed nanogrid, there are also integrated energy storage consisting of battery cells that are coupled together to a coherent unit. Measurement equipment is also implemented for analyzation of acting wind turbine as well as different types of safety equipment for redundancy in the system. In the nanogrid, a rectifier for AC to DC transformation is constructed. An inverter for DC to AC transformation is also implemented for supplying electricity to the equipment that are acting on the grid. The system is tested under real conditions. The whole system could observe partially function and configurated well to the various parts of the whole system. Further optimisation of some parts of the system from the prototype is needed.
