  1. 1. Uncertainty quantification for offshore wind turbines

    University essay from KTH/Matematik (Avd.)

    Author : Ziming Wang; [2022]
    Keywords : wind energy; uncertainty propagation; polynomial chaos; Rosenblatt transformation; quadrature; regression; vindenergi; osäkerhetsutbredning; polynomkaos; Rosenblatt transformation; kvadratur; regression;

    Abstract : Wind energy is a field with a large number of uncertainties. The random nature of the weather conditions, including wind speed, wind direction, and turbulence intensity, influences the energy output and the structural safety of a wind farm, making its performance fluctuate and difficult to predict.

  3. 2. Feasibility Study of Wind Turbine Blades Constructed in 1300 MPa Fossil-Free Steel : Finite Element weight optimization with respect to structural integrity by Abaqus and Tosca Structure

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Peter van der Brug; Sina Urban; [2022]
    Keywords : Abaqus; Tosca Structure; Wind Turbine Blade; Weight Optimization; High-Strength Steel; Fossil-Free; SSAB; Strenx 1300; DTU 10MW-RWT;

    Abstract : This study aims to perform a feasibility study on the DTU 10MW-RWT wind turbine blades constructed in the fossil-free high-strength steel 1300 MPa from SSAB. The acceptance criteria, on which the study is based, are taken from the DTU composite wind turbine model. A maximum weight of 41 000kg and a maximum tip displacement of 12.5 m are chosen. 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

  6. 5. 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
