文摘
- •
The electromagnetic vibration acting as a disturbance source for fault feature extraction in wind turbine generators is deduced.
- •
Cyclic coherence function is applied to detect bearing fault feature hidden in intensive electromagnetic vibration successfully.
- •
The fault mechanism of shaft current corrosion is illustrated and the precautions are given to prevent this fault in wind turbine generators.
