1. Analysis to reduce ice-related production losses for wind turbines
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : In the rapidly growing wind energy market, regions with cold climates are currently in the spotlight owing to their abundance of wind resources. However, the operation of wind turbines in cold climate conditions is challenged by serious icing problems. LÄS MER
2. Modelling of ice throws from wind turbines
Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : As the wind energy sector expands into areas with colder climate, the problem with ice throw will increase. Due to a rotor diameter of more than 120 meters for a typical modern turbine with an effect of 3.3 MW, the separated ice fragment will get a high initial velocity, and therefore, they will also be thrown a long distance.

3. Meteorological Investigation of Preconditions for Extreme-Scale Wind Turbines in Scandinavia
Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : During the last three decades, the hub height of wind turbines has increased from 24 to 162 meters and with an increasing demand for break-through innovations in green energy production it seems likely that this trend will continue. The meteorological preconditions for extreme-scale wind turbines are investigated for Scandinavia using 33 years of reanalysis data from MERRA (Modern-Era Retrospective Analysis for Research and Applications).
