In the "WindKI" research project, the Fraunhofer Institute for Wind Energy Systems IWES and the AI company LATODA are developing a new method that detects performance losses in wind turbines at an early stage. The aim of the multi-year project is to implement an AI-supported diagnostic system that will enable objective and data-driven performance optimization of the turbines. The project is funded by the German Federal Ministry of Research, Technology and Space.
Wind turbines do not always generate the amount of electricity predicted prior to their construction. There can be many reasons for this, such as unfavorable wind conditions, incorrect rotor blade angle settings, or aerodynamic effects in the wake of other wind turbines. To date, there is no reliable method for automatically detecting the causes of underperformance.
Innovative solution using AI methods
The WindKI project partners are specifically addressing these challenges: By combining measurement data, simulations, and artificial intelligence, they are creating a diagnostic system that uses heuristic algorithms and machine learning models to detect anomalies in the data set. The first models are based on high-resolution SCADA data sets from the 8-megawatt Adwen AD8 research turbine, which Fraunhofer IWES is providing for the project. On this basis, LATODA is developing an AI-based analysis system that automatically determines whether a turbine is operating as expected or is underperforming and suggests relevant parameters for optimization.
The AI not only reports anomalies, but also provides clues as to their probable causes – from rotor blade settings to unfavorable operating conditions. This gives operators a tool that helps them identify and rectify problems more quickly. The methodology enables the wind industry to develop customer-oriented AI models based on any time series data.
"The results of the project improve our understanding of the overall turbine dynamics," says Philipp Thomas, Group Manager Global Turbine Dynamics at Fraunhofer IWES. “The combination of expert knowledge and AI opens up new possibilities for the wind industry."
LATODA Managing Director Daniel Hein also emphasizes the importance of the cooperation: "With our algorithm for analyzing sensor data, we are creating the basis for fast and reliable fault diagnosis. This will significantly reduce failures and reduced performance."
The "WindKI" research project offers the opportunity to build a bridge between advanced AI techniques and conventional approaches in the field of wind energy. By linking domain knowledge from wind energy research with state-of-the-art machine learning methods, not only a concrete technical problem is solved, but also a framework for future, interdisciplinary research projects is created.
