Real-time Design Incident Structural feedback improvement analysis monitoring CASE STUDY Consistent damage to a number of Insensys sensors installed along blades Blade damage identified on 3 blades blades from unknown cause. to monitor bending moment. with bending moment imbalance. Situation An Operator managing a number of small wind farms in Europe approached us after identifying a number of turbines that were consistently su昀昀ering from blade damage. This was signi昀椀cantly increasing their operational costs and causing them excessive downtime. Solution Insensys carried our a retro昀椀t installation to monitor the condition of the turbine blades over a 14 day period. The sensors allowed an individual blade's bending moment to be monitored during operation. Diagnosis Upon completion of the 2 week test all data was post-analysed using Insensys algorithms. Insensys identified one turbine with a major issue (approx. 18% bending moment imbalance between the blades, and two more with minor imbalances). After investigation, the team determined that the cause of the blade with the major issue was damage due to lightning strike, the Operator was able to quickly carry out a repair returning the turbine to full operational capacity. Without Insensys this would not have been identified as quickly thus justifying the implementation of Insensys CMS..
