Here at IWES, we assess weather risks using the Advanced Weather Time Series Scheduling (AdWaTSS) method, which is more precise than just statistics, and frequencies of tasks. For the offshore wind industry, we analyze and verify the time schedules of…
The requirements for wind turbine test benches are continuously increasing and demand, in turn, investments in test bench expansions or new test benches. Fraunhofer IWES has developed a hybrid test procedure to expand the capacity of existing testing facilities and…
Over the years, we have witnessed rapid growth in both onshore and offshore wind turbine systems. At the same time, the entire wind industry has become even more competitive, as wind turbine manufacturers aim to launch their product on the…
Whenever we have the opportunity to look at damaged bearings, we as scientists love to do so. Be it the bearings we tested in our own lab or bearings directly from the field, it is always exciting to see what…
Fraunhofer IWES Wind Lidar Buoys floated in the German Bight, east of the Bard Offshore 1 wind farm, at times last year. These yellow buoys ensure that comprehensive wind measurement data and meteorological parameters can be precisely recorded and evaluated….
Ever since the construction of the first wind farms began in the 1980s, the impact of wind turbines on the flow – the wake effect – has been a major focus not only in the field of wind energy research…
Efficient use of materials and a long lifespan are important KPIs in the optimization of offshore wind turbines. For future, larger support structures, which are particularly expected in wind farms at greater water depths, the behavior of the foundations, in…
When the wind passes through the rotor disc of a wind turbine with its rotating blades, the wind speed behind the turbine is reduced – the turbine extracts kinetic energy from the wind to convert it into electrical energy. This…
Many analyses in the field of wind energy are based on virtual models. However, these simulation models are not freely available for every real wind turbine. Fraunhofer IWES solves this problem with an innovative approach. Researchers at IWES are currently…
Part 3: Rapid testing of blade bearings – The first endurance run. In Part 1, I introduced the idea of an accelerated endurance run for blade bearings, which would consist of all wear-inducing cycles in direct succession. In Part 2,…
