  1. 1. COMPARATIVE ANALYSIS OF WIND ATLASES: WIND RESOURCE ASSESSMENT OF FORESTED SITES FOR WIND POWER DEVELOPMENT

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Joel Thomas; [2021]
    Nyckelord :;

    Sammanfattning : Wind atlases are interactive databases used extensively for preliminary wind resource assessment aimed at optimal wind power development. The selection and processing of wind atlas data are important and will determine the quality of the subsequent WRA (Wind Resource Assessment) phases. LÄS MER

  3. 2. Case Study of Uncertainties Connected to Long-term Correction of Wind Observations

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Elisabeth Saarnak; [2013]
    Nyckelord :wind climate; uncertainty; long-term correction; Measure-Correlate-Predict; MCP; reanalysis dataset; seasonal variation; on-site measurements; vindklimat; osäkerhet; normalårskorrigering; Measure-Correlate-Predict; MCP; återanalysdata; säsongsvariation; vindmätning;

    Sammanfattning : Good knowledge about on-site wind climate is necessary in wind power assessments. Due to yearly and natural variability, short-term on-site measurements do not themselves give information about the wind climate. Long-term reference data can be used to correct the short-term observations to better correspond to a normal year. LÄS MER

  4. 3. Uncertainty Analysis of Long Term Correction Methods for Annual Average Winds

    Master-uppsats, Institutionen för fysik

    Sammanfattning : For the construction of a wind farm, one needs to assess the wind resources of the considered site location. Using reference time series from numerical weather prediction models, global assimilation databases or observations close to the area considered, the on-site measured wind speeds and wind directions are corrected in order to represent the actual long-term wind conditions.

  5. 4. Statistical analysis of wind data regarding long-term correction

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

    Författare :Christoffer Jonsson; [2010]
    Nyckelord :MATLAB; Measure-Correlate-Predict; Regression; NCAR NCEP; Seasonal dependence; Long-term Correction; Wind Analysis; MATLAB; Measure-Correlate-Predict; Regression; NCAR NCEP; Säsongsberoende; Långtidskorrigering; Vindanalys;

    Sammanfattning : The procedure of determining if a site is suitable for wind power production requiresconvincing statistical data describing the long-term behavior of the average wind speed.This can be achieved by measuring the wind speed for a short time period, e.g. a year,and after that a Measure-Correlate-Predict (MCP) method can be performed.
