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
In the work concerning experimental verification of thick airfoils, the focus has been on airfoils used by the industry. The method has been verified with measurements on a NACA 63-215 airfoil
The project objective is to develop more generally applicable assessment and design criteria for isolated power supply systems, and the expected result is a guideline for design of such systems.
The purpose of the project was to investigate how the rotor design of an existing wind turbine can be extrapolated to a 4 MW turbine. Within the project two optimization codes for optimizing a large
Transfer of technology and industrial cooperation require a common framework, thus a compilation and analysis of Russian wind load and other external conditions in relation to European wind turbine
The project constitutes a continously running 5 years research programme on aeroelasticity with the objectives to improve the basis for design and optimization of wind turbines, and establish an
The purpose of the project is to develop and test micrometeorological tools for the prediction and estimation of properties of the wind that are important for loads on wind turbines situated on land
The purpose of the project is to perform an experimental investigation of extreme load on wind turbines, measuring both the wind field and the structural load response on high wind speed sites.
