Dr.-Ing. Katharina Fischer

Katharina Fischer has been a Senior Scientist at Fraunhofer IWES in Hanover since 2012. After completing her degree in electrical engineering and earning a doctorate in mechanical engineering, she spent three years working as a postdoc at the Chalmers University of Technology in Gothenburg, Sweden. Since joining IWES, she has established a wide range of research activities in the fields of reliability, maintenance, and condition monitoring of wind turbines. The central role of field data analyses is common to all of them. She is dedicated to the optimal utilization of wind energy also in her spare time – as an avid windsurfer.

Power converter reliability: Field measurements illuminate climatic stress

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 conditions to which the power electronics are…

20,000 operating years: Data analysis generates added value from field data

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 more sensors and operating data with…
