Test and measurements

Evaluation of models and theories based on experimental work is fundamental to research in wind energy. Experimental methodologies are used both to test and evaluate theoretical models and to verify the performance of wind turbine designs and wind turbine component designs. This is a vital element in the understanding and quantification of the uncertainty in wind energy projects, and consequently an essential aspect in securing a competitive advantage of the wind energy industry. 

The research of this section is aimed at the development of instrumentation and new methods for experimental determination of wind turbine characteristics, including test methods for the wind turbine industry.

Special efforts are focused on remote sensing techniques using wind lidars. A major effort is the development of a new European research infrastructure called WindScanner. It is a laser-based remote sensing instrument for measurements of wind and turbulence in three dimensions around huge wind turbines.

The section also represents expertise in organising and conducting field meteorological measurements (wind resources and siting, boundary-layer meteorology, turbulence and aero-elastic design), and in providing instruments as well as data systems and data management for the Department of Wind Energy and external clients in the global wind industry. Research results are applied in international standards and also in national and international projects.

The Test and Measurement Section operates two test stations for large wind turbines at Høvsøre and Østerild on Jutland’s west coast. These areas have excellent conditions with high wind speeds and flat terrain. Therefore, we can verify both performance and the wind turbine design bases for all operating conditions relevant to large wind turbines up to 250 meters tall.
