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

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Manikanta Viswanadha Prabhu Kankatala; [2023]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  3. 2. Betesmönster hos älg (Alces alces) vintertid i fjällnära skog : En studie av födoval i relation till trädslagssammansättning och habitat

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Ella Hambeson; [2023]
    Nyckelord :Food choice; Alces alces; forested mountainous terrain; winter diet; selection; Betesval; Alces alces; fjällnära skog; vinterföda; selektion;

    Sammanfattning : Browsing patterns in large herbivorous mammals are complex and decisions regarding food items occur at different levels depending on internal or external factors such as energy requirements and available food sources. A broader understanding of the behavior of animals living in habitats of economic interests for humans enables human exploitation with as little impact as possible on the animals' habitats. LÄS MER

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

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

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

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

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

    Sammanfattning : 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.

  7. 5. WAKE INDUCED POWER DEFICIT ANALYSIS ON WIND TURBINES IN FORESTED MODERATELY COMPLEX TERRAIN USING SCADA DATA

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Esma Öztürk; [2018]
    Nyckelord :turbine wakes; wake interaction; wake losses; power deficit; SCADA data;

    Sammanfattning : Over the last few decades, wind power has shown a continuous and significant developmentin the energy market globally. Having reached a certain level in both technologyand in dimensions, the role of optimizing wind turbines as well as wind farms hasbecome an additional aspect to future development and research.
