  1. 11. QUANTIFYING ERRORS IN PITCH ANGLE POSITION USING BEM THEORY

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sai Varun Kollappillai Murugan; [2021]
    Keywords : NREL; Qblade; SCADA; Pitch angle errors; Wind turbines;

    Abstract : The wind industry is always seeking ways to better understand the performance of a wind turbine and improve its efficiency. During the operation phase and maintenance, wind turbines go through regular optimization. Due to the regular change in wind speed and direction, wind turbines need to be regulated and positioned accordingly. READ MORE

    Abstract : Due to the increase of rotor size in horizontal axis wind turbine (HAWT) during the past 25 years in order to achieve higher power output, all wind turbine components and blades in particular, have to withstand higher structural loads. This upscalingproblem could be solved by applying technologies capable of reducing aerodynamic loads the rotor has to withstand, either with passive or active control solutions. READ MORE

  4. 13. Structural temperatures of wind turbine blades under icing conditions

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Elise Brouillette; [2021]
    Keywords : Aerodynamics; Anti-icing Systems; Glass transition temperature; Heat transfer; Wind turbines;

    Abstract : As clean energy demand is on the rise and the wind energy sector in growth, locations with the highest wind potential are becoming of higher interest for wind farm projects, but they are located in colder regions. In cold climates, ice accumulation on wind turbine blades is a serious issue, both in terms of safety and performance. READ MORE

  5. 14. Performance analysis of a small-scalewind turbine at variable pitch and withpitch unbalance

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Francesco Mazzeo; [2021]
    Keywords : Wind energy; wind turbine; pitch angle; pitch unbalance; Blade Element Momentum BEM theory; Computational Fluid Dynamics CFD ; wind tunnel experiments; oscillations;

    Abstract : When it comes to design a wind turbine rotor, several parameters have to be taken into account. The present work focuses on the inclination of the blades with respect to the rotor plane, namely the pich angle. READ MORE
