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…
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…
A controller or control system is an essential wind turbine component. In modern wind energy turbines, stable operation is not possible without a controller. As a research associate at Fraunhofer IWES, I work in the field of control technology for…
Authors: Karoline Pelka and Dr.-Ing. Katharina Fischer Power converters are among the most frequently failing components of wind turbines. The causes remained unexplained for many years. Seasonal failure patterns point to environmental influences and shift the focus to the climatic…
Authors: Karoline Pelka, Vincent Wilms, Dr. Martin Dörenkämper Digitalization is on everyone’s lips. How can digitalization in the wind industry contribute to the improved competitive ability of renewable energies? One answer is the safe and uncomplicated sharing of wind turbine…
Authors: Dr.-Ing. Katharina Fischer, Karoline Pelka Wind turbines generate electricity – and a whole lot of data. The amount of data is growing continuously as the number of operating years increases, but also as turbines are equipped with more and…
