Canadian Wind Energy AssociationOPERATIONS & MAINTENANCE SUMMIT
Toronto
Wind Turbine Blades The most expensive components
Wind Generator Failures 7 – 10% caused by the rotor blades
lade Damage Commonly caused by lack of maintenance,
lightning strikes and fabrication defects
Without regular inspections and maintenance, blades will get damaged and lead to shut down
THE FACTS
With eyes and ears: Each time you are on site Visual check from ground and nacelle Abnormal sounds (whistling) Carbonization of lightning collectors
Rope Access Weather conditions
Suspended Platforms Time consuming
Remote Scope-Camera Fastest solution
New system installed at AVVto improve mobility and operation on field
Set up of Remote
Inspection Camera
Working Platform
Delamination-Debonding
Detector
On arrival on site Fabrication and transportation
During commissioning Lifting and installation
In-service inspection during the warranty period including repair activities
End of warranty period and claims filed on detected problems
Post-warranty inspections and maintenance work
Inspection Schedule (Records)
Materials Selection & Formulations: Related to temperature and weathering
conditions (Polymer)
Repair Method Wet molding (adhesive) Adherence (interface) Cure time (limitations)
Blade Access Ground – platform – rope
Safety Considerations
Mobile Laboratory
Cured Temperature Control
Infrared Heating
Large UV Light Prepreg Curing
Major importance of the end of warranty inspections and claims justification.
Availability of specialized composite technical resources.
Complete knowledge on blade design and its material composition.
