Wind Power

Wind Power

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 power, 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 »Wind Power« - Fraunhofer Energy Alliance

Wind Farm – Planning and Operation

Our member institutes contribute to the design and development of wind farms, especially in northern Germany. Numerous analyses of onshore and offshore areas are carried out and the planning reliability of wind farms is increased by innovative measurement methods.

Projects

 

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.

 

WInD-Pool

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

 

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.

Offshore Wind Power

Due to its great potential, offshore wind power plays a major role in the expansion of sustainable energy supply. In the future, up to 15 percent of energy consumption in Germany could be covered by offshore wind power. In research initiatives, institutes of the Fraunhofer Alliance 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.

 

OFT

The project »overall concept and initiation time and place differentiated offshore test field research (OFT)« creates the framework conditions for further research, development and demonstration of offshore wind farm in German waters.

Onshore Wind Power

As a key component of the energy transition, wind power technology must be continuously developed. Not only the use of offshore wind power plays a role here, but also the use of wind power in inland areas, including central and southern Germany. The Fraunhofer Alliance has set itself the goal of accompanying the expansion of inland wind power by developing novel systems and comprehensive analyses of wind conditions.

Projects

 

Smart Wind Farms

The project develops a comprehensive software tool for a priori optimization of wind farms during the design phase. it also develops and tests a control unit prototype for a wind farm using models to keep energy production costs as low as possible.

 

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 Turbines – Technology

The Fraunhofer Alliance 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 power are constantly being developed within the Alliance.

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.  

Power Converters for Wind Power Systems

The trend towards ever larger and more powerful wind turbines, which has become apparent in recent years, demands constant optimization with regard to the reliability of system technology. In this context, the Fraunhofer Energy Alliance develops processes and technologies for condition monitoring of power converters. The aim of the developments is to increase the reliability and thus the availability of the power converters and the connected components in wind turbines. We also develop control circuits for even and efficient load distribution as well as methods for early detection of malfunctions.

Projects

 

HiPE-WiND

In the »HiPE-WiND« project, the complete converter systems in 10 MW wind turbines are to be exposed to precisely definable loads in a climatic chamber with the goal of extending their service life and preventing failures.

 

Research Alliance High-Performance Electronics

Together with the University of Bremen, the Fraunhofer IWES is investigating the practical use of wind turbines.
