Introduction and objectives

Our Vision: To establish a new Danish large-scale mobile facility for wind energy and turbulence research with the aim to better measure, model and exploit the wind and its energy resource, in order to maintain Danish Worldwide lead in the wind industry.

Our Mission: To secure society’s continued exploitation of wind energy, primarily via assessing external wind conditions via direct measurements, and to assist technology transfer directly to wind turbine manufactures already established in Denmark.

Our aim is: To provide a major boost to wind turbine research by building an unprecedented facility that gives a complete 3-dimensional picture of the wind field, both in front of, and behind a huge wind turbine rotor.

The proposed new large scale facility Windscanner.dk addresses in particular these high prioritized needs:

1. The full 3-D picture: The proposed WindScanner.dk facility will enable measurement of the “full 3-D picture” of turbulence evolving in space and time, and will therefore stimulate major advances in our comprehension of the atmospheric wind and turbulence physics, giving impact both in terms of new aerodynamic designs and improved computer modelling.

2. Wind turbine Siting in complex terrain (hills, escarpments, moun-tains) and forested areas: There is a need to measure the wind, accu-rately and comprehensively, in complex terrain, including mountainous and forested areas where many of the future land-based wind turbines will be installed.

3. Studies of Wakes from wind turbine’s

4. Measure extreme wind speeds at high spatial and temporal resolutions in the atmospheric boundary layer.

Societal cost-benefit account

The benefits from WindScanner.dk facility cover research, commercial and socioeconomic aspects. The ability to measure the entire interaction between the wind turbine and the wind in real world complex conditions will provide a unique advantage that is not assessable today. The WindScanner.dk facility will enhance both the public and private research, since this research will be based on more valid measurements and thereby the researchers will make their conclusions on a better background.
Furthermore the WindScanner.dk facility has the potential to the increase the progress of a given development and thereby indirectly reducing the development cost relatively. But the WindScanner.dk facility will also result in a better understanding of how wind turbines should be designed, which can lead to better performance of a given wind turbine.

By implementing the research results based on the WindScanner.dk facility the commercial companies will be able to provide a wind turbine of a given size, and cost, with a better performance, which will improve their market position compared to other energy providers. Furthermore the WindScanner.dk facility will be able to measure complex real life conditions in a complex terrain far more accurate than the wind measuring methods of to-day.
This will lead to that a given wind turbine will be sited under more favourable wind conditions, which will improve the performance of the given wind turbine. Wind turbine manufactures entering this project as partners will receive these possible outcomes in a larger extent than other manufactures who begin to experiment with windscanner.dk facility later on. Society will naturally also benefit from any improvement in the performance of a given wind turbine.
