Analysis of turbulence models fitted to site, and their impact on the response of a bottom-fixed wind turbine
Nybø, Astrid; Nielsen, Finn Gunnar; Godvik, Marte (Journal article; Peer reviewed, 2021)This study compares a wind field recommended by the wind turbine design standards to more realistic wind fields based on measurements. The widely used Mann spectral tensor model with inputs recommended by the standard, is ... -
The COTUR project: remote sensing of offshore turbulence for wind energy application
Cheynet, Etienne; Flügge, Martin; Reuder, Joachim; Jakobsen, Jasna Bogunovic; Heggelund, Yngve; Svardal, Benny; Saavedra Garfias, Pablo Andres; Obhrai, Charlotte; Daniotti, Nicolo; Berge, Jarle; Duscha, Christiane Anabell; Wildmann, Norman; Onarheim, Ingrid Husøy; Godvik, Marte (Journal article; Peer reviewed, 2021)The paper presents the measurement strategy and data set collected during the COTUR (COherence of TURbulence with lidars) campaign. This field experiment took place from February 2019 to April 2020 on the southwestern coast ... -
Evaluation of different wind fields for the investigation of the dynamic response of offshore wind turbines
Nybø, Astrid; Nielsen, Finn Gunnar; Reuder, Joachim; Godvik, Marte; Churchfield, Matthew J. (Journal article; Peer reviewed, 2020)As the size of offshore wind turbines increases, a realistic representation of the spatiotemporal distribution of the incident wind field becomes crucial for modeling the dynamic response of the turbine. The International ... -
Quasi-static response of a bottom-fixed wind turbine subject to various incident wind fields
Nybø, Astrid; Nielsen, Finn Gunnar; Godvik, Marte (Journal article; Peer reviewed, 2021)In the design of offshore wind farms the simulated dynamic response of the wind turbine structure includes loading from turbulent wind. The International Electrotechnical Commission (IEC) standard for wind turbine design ... -
Sensitivity of the dynamic response of a multimegawatt floating wind turbine to the choice of turbulence model
Nybø, Astrid; Nielsen, Finn Gunnar; Godvik, Marte (Journal article; Peer reviewed, 2022)In the design of offshore wind turbines, it is important to make a realistic estimate of the wind load. This is particularly important for floating wind turbines, having natural frequencies in a frequency range where the ...
