EloQuENT
Effective Loads Quantification in Enhanced and Natural Turbulence
Publieke samenvatting / Public summary
Aanleiding
Knowledge of the wind conditions in a wind farm is important for a good prediction of the power performance and expected energy yield, as well as to gain insight into the response of the wind turbine, for design and understanding of potential failures. Currently it is not common practice, during pre-construction site assessment or in operations, to fully investigate the shear (vertical or horizontal change in wind speed) or veer (usually vertical change in wind direction). Instead, a simple “shear profile” is fitted to the data, which may result in inaccurate estimation of both power output and turbine loading.
Doelstelling
The main goals of the EloQuENT project are to quantify the improvement in turbine loads assessment using measurements of the wind field instead of a point measurement at hub height and to develop a method that provides the appropriate wind field characterization for loads assessment.
