  1. 1. A COMPARISON OF THE OBSERVED WAKE EFFECT WITH SEVERAL WAKE MODELS USING BOTH ANALYTIC AND CFD SIMULATION METHODS - FOR THE CASE OF BLOCK ISLAND OFFSHORE WIND FARM

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Robbie Pratt; [2019]
    Keywords : Block Island Wind Farm; Offshore Wind Power; Wake Effect; Wake Modelling; WindPRO; WindSIM; Openwind; CFD modelling.;

    Abstract : This paper sets out to analyze the observed wake effect at Block Island Wind Farm. A comparison is made between several wake simulation methods and the observed data at Block Island using analytic and CFD (Computational Fluid Dynamics) modelling methods. READ MORE

  3. 3. Quantify Change in Wind Turbine Power Performance Using Only SCADA Data

    University essay from KTH/Kraft- och värmeteknologi

    Author : Marcus Carlberg; [2015]
    Keywords : ;

    Abstract : The power performance characteristic of a wind turbine is defined by its power curve and resulting estimate in annual energy production. It is a key attribute for validating the performance of newly installed wind turbines, and the power curve is monitored throughout the wind turbine life cycle. READ MORE

  4. 4. How bats are affected by wind turbines

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Maja Jonholm; [2015]
    Keywords : Biology and Life Sciences;

    Abstract : In this study a wind power park of five turbines, Gummaråsen, in the south west of Sweden have been investigated to find out if bats fly in the height of the rotor blades, what species are present and the abundance of bats, at the site. The result showed that no bats was flying close to the wind power turbine, at the height of the nacelle (machine housing) and rotor blades, but bats were present closer to the ground. READ MORE

  5. 5. Investigating Wind Data and Configuration of Wind Turbines for a Turning Floating Platform

    University essay from KTH/Mekanik

    Author : Nurcan Sönmez; [2014]
    Keywords : Offshore Floating Turbine; Offshore Floating Structures; Jensen Wake Model;

    Abstract : Wake interactions on a floating platform for offshore wind energy applications were investigated. The study is performed in collaboration with Hexicon AB which has a patent family for innovative floating platforms, which are able to turn automatically. READ MORE
