Based on the dynamic characteristics, multi-fractal theory is put forward to detect and recognize the working status of the main bearing of megawatt wind turbines. Different working states are recognized intuitively by different dimensions of multi-fractural which are sensitive to variety of working ...

Add fields for diameter (rotor:diameter) and height (height:hub) of wind turbines (#241) Remove field for undocumented and (essentially) unused tag water_volume (was used on Fire Hydrant preset) Update roof:colour field to new colour field type (#647) Add cables field to presets for Power...
Most direct drive wind turbines have radial-flux generators. Jeumont is the only company to have built direct drive wind turbines with axial-flux machines. Several people investigated axial-flux generators (Lampola, 2001). Although axial-flux machines may be smaller than radial-flux machines, they...
Another field-proven radial shaft seal for wind turbines is made of the material HNBR (Hydrogenated Nitrile Butadiene Rubber). It provides a constant line force on the sealing lip to securely handle all types of oil or grease-lubricated bearings. A special feature, the so-called rubber lock (...

The digital twin serves two main purposes: a.) Acting as a performance watchdog where a physics-based model of the wind turbines calculates theoretical output, taking into consideration the current weather conditions, comparing the theoretical output with the actual output, and flagging any anomalies...
