In the lifespan of a wind turbine, the gearbox is replaced on average four times due to wear and tear. All together this is almost the cost of a new turbine.
In June 2011, a hitherto unparalleled demonstra- tion of wind lidar performance was obtained in the calibrated wind tunnel belonging to LM Wind Power, Kolding Denmark:
Grid connection and electricity production optimisation from a 500 kW Wave Star wave power unit located at Horns Rev. The project is closely linked to project 10239. If the project achieves the
Given the goals of 50% of electricity production being generated as wind energy and typically from large offshore wind farms in 2025, Denmark needs more exact forecasts - especially forecasts looking
The Megavind Partnership was founded in 2006 and the project 2008-2010 is a continuation of the earlier stages of the partnership. It has been the goal of the partnership to establish the foundation
The work is a part of the international cooperation to the IEA-Wind Implementing Agreement, and belongs to a new task - Annex 28: Social Acceptance of Wind Energy Projects. The project has collected
The purpose is to build a 500 kW wave energy demonstrator for the North Sea, as a first very important step towards commercialisation of wave energy. The EUDP funds mainly cover the very extensive
This project is motivated by the vision of being able to understand and model complex structural mechanisms and failure in large composite structures such as current and future wind turbine blades
The project is based on a previously tested 1:40 model of a new type of wave energy converter, which has so far shown good properties. The objective of the project is to measure loads on the
The project aims at developing a meteorological software tool for large wind farm planning. The project is based on data from previous projects on large wind farm shadow effect. The existing tools
The project focuses on a theoretical and experimental study of floating platforms for wind turbines, wave power systems and the relationship between wind and wave power. The project basis is the
The first step is to combine a hydrodynamic model of the waves with a dynamic model for the mechanical and hydraulic PTO system to achieve an understanding of the principles behind optimising energy
Optimization of power production and reliability of the Wave Star prototype in Hanstholm. The funding is given as a temporary additional per production hour, and is activated by attainment of
The project will test the abilities of the wave wing as an energy absorber. The test will be performed in the wave tank at AAU following preparation of measuring setup, component list and plan for
The objective is to improve the design basis for large wind turbines by measuring wind and turbulence profiles at high altitude above a flat ground using modern instruments. The project will study
The vision is that the increased research on main wind turbine uncertainties and risk & reliability will lead to less conservative designs and more cost-efficient wind energy. Therefore, careful
The usage of new reinforcement fibre and resin systems allows for novel forms of blade design, cost optimisation and production methods that significantly reduces the production time.
The cooperation project is conducted with a PhD study as its central element and its research will be used directly in wind turbine and wnd farm development so as to prepare common guidelines under
Acoustic measurements will be performed at various degrees of wake using several measuring techniques. The results will be compared with aerodynamic measurements to enhance knowledge of wind turbine
