The main points of the project are: 1) Improved methods for modelling of vertical and horizontal variation of wind speeds. 2) Verification, calibration and improvement of acoustic sensors for remote
The object of the research-project is to select which methods will give the best simulation of environmental influence in relation to the geographical placing of the mills, to be able to select what
The project concerns the modelling of aerodynamically generated sound from wind turbines with the aim of predicting and reducing noise emission from wind turbines.
Background: Planning wind farms offshore are generally based on little knowledge of the wind speeds. It is due to the limited amount of offshore meteorological observations worldwide. This again has
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
