Dr. Edward Hart

Royal Commission Brunel Research Fellow Wind Energy and Control Centre, UK

Conference day I, Tuesday, 20 June 2023

9:30 AM Challenging the applicability of ISO standarts and design assumptions for wind turbine main bearings

• Transparent deep dive into MB replacement statistics and reported damage for

~15GW of wind capacity

• Characteristics and features of real-world main bearing operational loading and conditions

• ISO equations, assumptions, and applicability in this case

• The value of turbine certification on wind farms where the MB’s failure rate is above 10% before the certified lifetime

• Roadmap for the identification of root-cause and possible solutions 

12:50 PM A strategic dive into the industry’s lack of an international standard about grease cleanliness during operation for avoidance of hard particles lamination

• How hard particles lamination is detrimental to MBs

• What size of hard particle will initiate lamination for MBs in the highly variable operating conditions in wind?

• Particles nature and size characterization

• Harmonization of sampling port/sampling procedure, analyses and interpretation

• Is wear particles in grease a reliable methodology?

• Can wear particles in grease early identification allow mitigation, life “extension” and failure avoidance?
