  1. 1. Data analysis and wake modelling ofthe Lillgrund wind farm

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Alessandro Sebastiani; [2019]
    Keywords : ;

    Abstract : This work consists of two parts: the analysis of the operating data collected at Lillgrund between December 2007 and March 2018, and the implementation and evaluation of three wake models. Operational and meteorological data from the Lillgrund wind farm have been analyzed to assess the aerodynamic efficiency and general performance of the farm. READ MORE

  3. 2. Optimal Placement of FloatingTwo-Turbine Foundations in Offshore Wind Farms

    University essay from KTH/Energiteknik

  4. 3. Defining the Wake Decay Constant as a Function of Turbulence Intensity to Model Wake Losses in Onshore Wind Farms

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jochanan Kollwitz; [2016]
    Keywords : N.O. Jensen model; wake losses; onshore; wind farms; forested terrain; wake decay constant; turbulence intensity; windPRO;

    Abstract : Modelling the wake effect generated by wind turbines is an essential part for calcu- lating a wind farm’s expected energy production. Operating wind turbines disturb the flow of the wind, which results in decreased production of downwind turbines. The N. O. READ MORE

  5. 4. Development of a pitch based wake optimisation control strategy to improve total farm power production

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jun Liang Tan; [2016]
    Keywords : Wake reduction; Jensen Wake Model; Particle Swarm Optimisation; Wind turbine Control Algorithm; Deterministic Wake Modelling; Heuristic Optimisation model;

    Abstract : In this thesis, the effect of pitch based optimisation was explored for a 80 turbine wind farm. Using a modified Jensen wake model and the Particle Swarm Optimisation (PSO) model, a pitch optimisation strategy was created for the dominant turbulence and atmospheric condition for the wind farm.
