The project endeavoured to calculate electricity generation costs in modern onshore wind turbines. At average operating costs of DKK 0.08/0.10/kWh, production costs per kWh can be calculated at DKK 0
To extend the life of gear oil - not least for use in offshore wind turbiens - the project aims to investigate whether nano-filtration using CJC filters (cellulose fibres) with zeolites eliminates the
The project constituted a phase of the strategic partnership between Risø DTU and the wind turbine industry on developing an aeroelastic design complex. The project worked with the following issues
Aalborg University and Risø/DTU have developed a model to estimate responses and structural reliability of wind turbines under normal operation. Various Monte Carlo simulation algorithms were tested
Today, wind turbine control systems are designed separately from its structural, aerodynamic qualities, but to achieve cheaper, more reliable wind turbines, the design phases need to be united into
The project studied sediment bed conditions, scour/erosion, and quick-sand-like conditions that may occur due to the effects caused by wave and current action. Illustration from laboratory experiment
On a hot windy summer day, with beautiful clouds in the sky, the air is full of turbulence, like a hot pot of boiling water. In these unsteady surroundings a bird of prey is hovering, completely still
This project has validated the use of the noise prediction model Nord2000 for more detailed noise prediction from wind farms compared to conventional methods like the ISO 9613-2.
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 purpose of this project has been to extend the foundation module in HAWC and FLEX to be able to simulate the frequency dependent stiffness and damping of the foundations.
The Project is a preliminary study of the possibilities for realization of 'Wind Power Academy' on Lolland. The vision of a Wind Power Academy was made as Energi E2 decided to establish a new park of
