Turbulent wind flow affecting the wind turbines structure and significantly reducing the energy production. Traditional modelling methods of this complex phenomena require enormous computational resources and time, and therefore not widely used by wind farm operators. On the other side, artificial intelligence based tools for wind energy yield and failure prediction are rather standard nowadays, at least at the major turbine manufacturers. But none of those models were taking a turbulent flow into account until now. Here we are presenting a new approach, where machine learning is applied to stream data processing. Time series data of wind turbine gearbox censors are utilised to assess whether a wind turbine experiences an excess load due to a turbulent flow and to estimate turbulence intensity. This information used further for classification of turbulence impact and decision support for turbine cut-off to prevent structural damage to gearbox mechanism. The approach has been validated on real production data from several offshore wind turbines. In this approach kernel based reinforced learning is optimized to fit a time frame of real-time data analysis and unsupervised learning is used to cluster data sets and forecast possible turbine overload.
