The objectives of this project is to improve on the current practice of basing performance evaluation on a single point measurement of wind speed and instead introduce a method where the wind field
This project has investigated noise emissions from large-scale wind turbines in relation to small-scale wind turbines. In addition, noise nuisance at low frequencies was investigated, noise
The aim of the project is to develop a simulation platform for generation of relevant wind fields applicable for aeroelastic design simulations. This is achieved by development, verification, and
The annex will give the participants an overview of the technical and environmental assessment challenges encountered in offshore applications and help them to understand the areas of further R and D
The wind farm output of an offshore-farm such as Horns Rev changes between nearly constant output to highly variable power output. A balance responsible would benefit from knowing the variability of a
The object of the project was to determine the wave impact on wind turbines and test ways to reduce such impacts. The project showed that all major wave loads are caused by breaking waves and that
The project developed a computer method for quantifying wind turbine structural loads caused by fault ride-through (FRT) requirements. Exemplified in the case of an active stall wind turbine this
The objective of the project was to participate in the IEA annex 'Dynamic models of wind farms for power system studies'. The objective of the IEA annex is to establish an international forum for
The main objective of Annex XVII is to provide wind energy planners and designers, as well as the international wind engineering community in general, with easy access to quality controlled measured
The main objective of the project is to implement controller design of wind turbines in the general design process, on the same level as structural dynamics and aerodynamics. Specific focus is on
Background: Within the Aeroelastic Research Program carried out from 1997 to 2002 by Risø and DTU a coordinated and continuous work has been carried out on the development of advanced computer models
