1. 6. Modeling of the trajectory of ice thrown from a wind turbine

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Elena Rocchi; [2023]
   Nyckelord :Ice thrown - Ice fall - RANS - LES - CFD - simulations - ballistic model; Technology and Engineering;

   Sammanfattning : There is a growing number of wind turbines installed in cold temperature zones as a result of the restricted space for new construction. Due to ice deposition on the turbine blades, the increasing installation of wind turbines in freezing temperature areas presents many challenges: ice accumulation increases weight, unbalances the rotor, diminishes aerodynamic efficiency, and creates safety issues.

3. 7. 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 fysik

   Författare :Emelie Sjökvist; [2023]
   Nyckelord :;

   Sammanfattning : 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

4. 8. Simulation Model - Grid Connection of a Marine Current Power Turbine

   Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

   Författare :Muhammad Farooq Mazhar; [2023]
   Nyckelord :Power electronics; Filters; Marine-current turbine; Grid connection; Damping;

   Sammanfattning : Renewable energy is a reliable source of energy and can provide promising solution to the on-going energy crisis if harnessed properly. Some of the common energy sources in which a lot of research is invested include wind,solar, water and biofuels. LÄS MER

5. 9. WEAR RESISTANT MULTI FUNCTIONAL POLYMER COATINGS

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Pranay Kumar Parsi; [2023]
   Nyckelord :Polymer coatings; Materials; Tribology; Wear resistant; Ice adhesion; Freezing delay; Anti-icing de-icing;

   Sammanfattning : This study aims to develop coatings which show wear resistant behaviour along with multiple functions such as improved ice adhesion, better freezing delay etc which help in improving the effectiveness of the wind turbine efficiency. The significance of anti-icing/de-icing solutions for wind turbines is emphasized since ice accretion can cause serious issues in generation of power and might lead to damage of blades. LÄS MER

7. 10. Wind Turbine Installation Methods: Investigating Increasing Turbine Heights

   Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :William Anderson; [2023]
   Nyckelord :Installation; Construction; Large-scale; Turbine;

   Sammanfattning : There is limited information available regarding the strategies surrounding the construction and logistical issues that will be faced in connection with the up-scaling of wind turbine technology. As wind turbines are manufactured at greater sizes, the industry will need to face these issues head-on to avoid many obstacles pertaining to transportation from the manufacturer to the project site, and the installation of massive turbine components at soaring heights.
