1. Improvement of Wind Power Forecasting and Prediction of Production Losses Caused by Ice Formation on Wind Turbine Blades : - A Machine Learning Approach
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : In the ongoing climate crisis, transitioning to renewable energy sources is essential to manage the increasing energy demand. One such renewable energy source is the weather-dependent energy source, wind power. Many wind farms are located in Cold Climate (CC) regions, known for their vast potential for wind power production. LÄS MER
2. 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
3. Major Component Replacement on Floating Wind Turbines
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Among the challenges that floating offshore wind (FOW) energy faces today, operation and maintenanc ecosts, and especially major component replacements (MCR), are an important cost reduction lever. MCRs are defined as any failure on a wind turbine requiring the change of an entire main component of the turbine, such as a gearbox, generator, blade, nacelle, etc. LÄS MER
4. Dimensionering och konstruktion av passiv mekanisk pitch för småskaliga horisontalaxlade vindkraftverk
Kandidat-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskapSammanfattning : För vindkraftverk i mindre skala används i huvudsak två sätt att avlasta vid höga vindhastigheter, stallreglering och girning ur vind. En tredje metod är att pitcha rotorbladet till en mindre attackvinkel. Då minskar belastningen på rotorbladet samtidigt som effektgenerering kan bibehållas. LÄS MER
5. Early Gear Failure Detection in Fatigue Testing of Driveline Components
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : Early failure detection has been an integral part of condition monitoring of critical systems, such as wind turbines and helicopter rotor drivetrains. An unexplored application of early failure detection is fatigue testing of driveline components. LÄS MER
