Turbine operation: Control systems keep everything running smoothly

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…

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…
