Changes over time for the structural vibration spectrum signature of both the turbine blade and support steel structures are important indicator of substantial degradation. Any substantial fractural of any of the structures produces exception in the vibration signature should alert the operational team of potential dangers requiring immediate attention and inspection.
- Real-Time Vibration-Shock Monitoring for Unforeseen Fatigue and Mechanical-Structural Vibrational Events at distributed over rotor blade and support structures
- Applicable to erosion induced structural degradation of the wind turbine blade.
- Also applicable to monitor the corrosion induced structural degradation of the monopile and upper support structures.
Real-time Stress-strain and mechanical spectrum monitoring along with erosion and corrosion damages for operational efficiency and safety. Exceptional changes in the mechanical vibrational spectrum under stress is a good signal for immediate attention and inspection.
Most wind turbine mechanical failures are initiated by rotor blade failure that induces the supporting structure to exceed its load limits and fails. The onsite is typically started with stress concentration due to specific areas having stress induced cracking. AVANTE Online Real-Time Structural INTEGRITY SPECTRAMECHANIC™ Erosion and Corrosion Sensor Monitoring System is designed to provide real-time alert in case of detecting exception in vibration spectrum induced by cracking along the wind turbine blade or the support tower structure.
