  1. 1. Optimization of loads and power production for wind turbines in Swedish conditions

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Manikanta Viswanadha Prabhu Kankatala; [2023]
    Keywords : ;

    Abstract : The project aims at quantifying differences in power production and fatigue loads for wind turbines placed in the Baltic sea and in forested, topographically-complex areas compared to turbines placed offshore and in flat terrain. Based on these results, suggestions will be provided on how to optimally site and operate turbines in these conditions. READ MORE

  3. 2. APPLICATION AND VALIDATION OF THE NEW EUROPEAN WIND ATLAS: WIND RESOURCE ASSESSMENT OF NÄSUDDEN AND RYNINGSNÄS, SWEDEN

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Heeyeon Cho; [2020]
    Keywords : New European Wind Atlas; NEWA; Wind resource assessment; WindPRO; WindSim;

    Abstract : The New European Wind Atlas (NEWA) was developed with an aim to provide high accuracy wind climate data for the region of EU and Turkey. Wind industry always seek for solid performance in wind resource assessment, and it is highly affected by the quality of modelled data. READ MORE

  4. 3. Above-ground biomass estimation in boreal productive forests using Sentinel-1 data

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : David Roc Roc; [2019]
    Keywords : synthetic aperture radar SAR ; backscatter intensity; InSAR; interferometric coherence; LIDAR; above-ground biomass; forestry;

    Abstract : Estimation of biomass has high importance for economic, ecologic and climatic reasons due to the multiple ecosystem services offered by forested landscapes. Measurements that are taken in the field incur personal and economic costs. Nevertheless, biomass surveying based on remote sensing techniques offer efficiency thanks to covering large areas.

  6. 5. 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
