Fault Diagnosis Method for Wind Turbine Equipment Based on Quaternion Graph Frequency Domain Transform in High-Dimensional Sensing Data

Wind turbine units are subjected to fluctuating loads, intense noise, and complex operating environments over long periods, making it easy for the faint fault signatures of components such as gearboxes, bearings, and drive trains to be masked. A fault diagnosis method employing quaternion graph frequency-domain trans...

Method for enhancing the amplitude of fault features in wind power equipment via complex cepstrum-assisted optimization

Precise diagnosis of rolling bearing health conditions is essential for reducing the maintenance costs of rotating machinery. To overcome the limitations of conventional spectrum segmentation methods, which rely on fixed filter banks and struggle to adapt to complex modulation characteristics, this paper proposes a cep...
