The objective of the project was to build a demo-plant applying a new d.c. technology and to test in an onshore location with the purpose to investigate technical and financial possibilities for a d.c
This project involves experimental verification of three Risø-A airfoils to evaluate their application on Danish wind turbines. The Risø-A airfoils were designed for both stall and pitch regulation by
The project is the first step in a research effort with the overall objective to prepare technical guidelines for grid connection of wind farms to weak grid, and to identify and develop technical
This Annex had as the main objective to set up an aerodynamic data base with experimental results from detailed rotor measurements. The participants in Annex XIV were the five different research
1) To investigate whether the commenly used assumption about Gaussian (normally distributed) turbulence is valid, and possible consequenses of deviations from Gaussianity on load calculations, that
This project has compiled data to allow the Danish manufacturers of wind turbines and blades to improve their knowledge of double stall. On the basis of the double stall difficulties different types
In an earlier research project competitive and cost effective wind turbine foundations in steel were developed. One of the developed foundation types was the mono pile. The present project comprises a
The main result of the investigation is a new developed method to identify the effective damping for the edgewise blade mode shape for wind turbines. The method consists of an exciter mechanisms which
The activities in 1996 has to a large degree followed the budget proposal of 27 June 1995. During the year two IEA Executive Committee meeting were held, first in Finland and then in Germany. The

The key target for the proposal is - by combining the latest technology related to generators and power electronics with the latest in wind turbines - to develop a new generation of grid-connected
This project will focus on the possibilities for achieving higher power production, less mechanical stress and a greater degree of flexibility by using both pitch and variable speed control in
A status has been performed within the research area 'Aeroelasticity for Wind Turbines', and on this basis, demands for research and perspectives for a future effort are identified.
The objective is to analyse and describe the edgewise vibrations, which have been observed during stalled operation on Danish and foreign 19 m wind turbine blades, and further to improve the models
A study has been performed, which investigated the possible application of Doppler laser anemometry for performance assessment and control of wind turbines.
It is the aim of the project: 1) To supplement the existing offshore wind data base, by setting up offshore meteorological measurements significantly further away from the coast than previously and
