Wind Energy

Wind turbines continue to get larger and heavier and, thus, place new demands on materials and construction. In order to prove the technical reliability of these turbines, special testing procedures and simulation methods are being developed. For example, the stability and structural dynamics of rotor blades and supporting structures are being examined. In the sector of offshore wind energy, experts carry out site investigations and aeroelastic simulations in order to define the overall dynamic of the offshore wind turbine in combination with factors such as wind, sea condition and subsoil. Moreover, the Fraunhofer Energy Alliance develops strategies and technologies for maintenance and offers comprehensive services for the management and grid integration of wind turbines.

Competences of the Fraunhofer Energy Alliance in the field of Wind Energy

Wind Turbine Technology

The Fraunhofer-Gesellschaft offers a broad portfolio of services for both offshore and onshore wind turbines: Functional layers, sensor technology, control systems, as well as databases and monitoring programs for wind energy are constantly being developed.

Projects

 

WInD-Pool

The acronym WInD-Pool stands for Windenergy-Information-Data-Pool. It is a common knowledge base of the wind industry.

 

EcoSwing

EcoSwing has taken the application of superconducting technology to a new level. Tests under realistic conditions were essential to reduce uncertainties.

 

Windmonitor

The windmonitor delivers news and results on onshore as well as offshore wind energy farms. The project is sponsored by the Federal Ministry of Economics and Energy.  

Wind Farm and Wind Turbines – Planning and Operation

The institutes of the Fraunhofer Energy Research support their customers in the design and development of wind farms. Numerous analyses of onshore and offshore areas are carried out and the planning reliability of wind farms is increased by innovative measurement methods

Projects

 

LiMeS

Optimization of measurement strategies for determining wind potential with LiDAR – Fraunhofer IEE starts research project with industrial companies and universities.

 

RAVE

The research Initiative carries out research and development work on the offshore test field alpha ventus. It generates experience and knowledge that advance the construction and further development of offshore wind energy.

 

NEWA

»NEWA« is an ERANET+ project with a consortium of nine member states and their national consortia. It aims at developing a new European wind atlas.

Offshore Wind Energy

Due to its great potential, offshore wind energy plays a major role in the expansion of sustainable energy supply. Institutes of the Fraunhofer-Gesellschaft accompany the construction and operation of test fields and carry out extensive monitoring and analyses of the highly stressed components and wind measurement experiments.

Projects

 

MALIBU

The aim of the »MALIBU« project is to develop a model which describes the effect of the external influences on measurement performance.

 

RAVE

The research Initiative carries out research and development work on the offshore test field alpha ventus. It generates experience and knowledge that advance the construction and further development of offshore wind energy.

 

ELMEDA

The foundation of offshore wind turbines is welded together from numerous pipes. The aim is to develop a sensor belt that can be placed directly around a weld seam in order to permanently check it for fatigue cracks.
