Comparison of field survey results with the data obtained on the large-scale test rigs will significantly expand the opportunities for further optimization of measuring and testing methods as well as risk mitigation for new turbine designs.




The two branches of Fraunhofer IWES are to become independent institutes

The Executive Board and Senate of the Fraunhofer-Gesellschaft have therefore decided to continue the branches of the institute as independent institutes as of January 2018: as “Fraunhofer Institute for Wind Energy Systems IWES“ and “Fraunhofer Institute for Energy Economics and Energy System Technology IEE“.



Prevention of Rain Erosion on Rotor Blades

Within the “BeLeB” project, the effectiveness of known protective mechanisms for rotor blades will be improved. Consequently, less resources need to be invested in repairs and maintenance. The development of reliable forecasting models for erosion damage and the assessment of practice-relevant repair concepts will contribute to this target.



Contract for Nacelle Testing for 8-MW wind turbine signed

The prototype of the new offshore turbine from Siemens Gamesa Renewable Energy is set to undergo extensive hardware in the loop testing in the DyNaLab from April 2018 until the end of the same year. The focus will be on the performance of the generator and the turbine’s grid compatibility.
