Wind Turbine Gearbox Fault Diagnosis Based on Pncc-Stft Voiceprint Feature Extraction and Gdc-Resnet
Abstract Due to harsh operating environments and wear caused by long-term use, wind turbine gearboxes often suffer from various faults, which lead to the emission of different noises or abnormal sounds during operation. This seriously affects the normal operation of wind turbines and their power generation efficiency.
