Latest Patents

One of Jun Wang's latest patents involves a method for detecting faults in wind turbines. This innovative approach includes obtaining a first signal from a generator of a wind turbine and a second signal from a vibration sensor coupled to the wind turbine. The first signal represents the output current of the generator, while the second signal is a time-sampled representation of vibrations from a bearing in the wind turbine. The method further involves determining a shaft rotation frequency signal from the first signal, which indicates the time-varying rotational speed of the turbine's shaft. By resampling the envelope of the second signal based on the shaft rotation frequency signal, a third angular sampled signal is created. This allows for the detection of faults in the bearing of the wind turbine by identifying characteristic signatures of bearing faults in the third signal.
