Certification of Electrical Characteristics of Power Generating Units

Significant advances have been achieved in the testing of gears, bearings, couplings, main shafts, generators, and converters through the replication of real operating conditions with special grid scenarios such as extreme and fatigue loads. An accelerated certification process makes it possible to schedule the launch of a pioneering new turbine concept precisely.

Accredited Rotor Blade Testing

Fraunhofer IWES sueccssfully passed the accreditation audit for “full-scale structural testing” (IEC 61400-23:2014) of DakkS ILAC. Advancing testing methods further is a permanent goal and will be intensified over the next years: technical performance and efficiency will be remarkably improved.

Measurement of Offshore Site Conditions

Exact knowledge of the site conditions is of the utmost importance when planning and erecting offshore wind farms. In order to be able to document this with a high level of accuracy, Fraunhofer IWES has developed innovative measuring technology, which is optimized for the requirements of offshore wind energy use and employed all over the world.

Experimental Validation of Support Structures

Support structures form a central aspect of the entire wind turbine system from both a technical and an economic perspective - along with the installation expenditure, they account for up to a quarter of the total investment costs. Reliable, validated models for support structures and their interactions with the substrate and turbines are therefore essential for the purposes of cost optimization and reducing the technical/ economic risk for every onshore or offshore wind turbine construction project.

Ground broken for New Test Stand for Generator/Converter Systems

Work recently got under way on the Institute’s latest construction project, a 250 m2 hall for generator/converter systems in the direct vicinity of the nacelle test stand in Bremerhaven/Germany. The new test stand is set to accelerate electrical certification testing of wind energy turbines at considerably lower costs than testing a whole nacelle.

EcoSwing Superconducting Generator Proves Itself on the Test Bench

The generator developed in the EcoSwing research project, is to be used in the next generation of multi-megawatt turbines. A test campaign on Fraunhofer IWES’ nacelle test bench showed good results due to the functionality of the overall system. 

 

Suction Buckets: Large-Scale Test Reveals Increased Tensile Capacity During Storms

Fraunhofer IWES tested two large-scale suction buckets in a 1:5 scale in early 2018. The physical experiments at the Test Center for Support Structures in Hanover (TTH) are the first of their kind in Germany. Within the experimental work the IWES researchers were able to quantify an effective temporary increase in tensile capacity during storms.
