01.05.2022To match the effects of wind field characteristics on bearing fault types, the bearing fault signals are regrouped. In other words, three sets of bearing fault signals are constructed, and these sets separately contain more ball faults, outer race faults, and inner race faults. This approach allows us to utilize different diagnostic methods for different wind farms, thus
