• Static loading – generally constant
• Cyclic loading – quasi static & dynamic cycling
• Stochastic loading – random variations
• Aerodynamic loading – force of the wind
• Mechanical loading – gravity, gyroscopic, transient

• IEC 61400-2: 2006 requires an aeroelastic approach
• No simplified load model for VAWTs hence no standard design filedesign file
• large number of load cases
• differences in the software implementation
• challenging for both the designer and CB – guidance is at best vague

• power performance issues – self start (savonius) or ‘motored’ up consequences for AEP
• issues in duration – net positive power flow….. • issues in duration – net positive power flow…..
• safety and function – dynamic behaviour observations
• supporting structure – currently excluded
• braking, shutdown and protection

• Power production• Power production plus occurrence of fault• Normal shut down• Emergency or manual shutdown
Aeroelastic load cases
• Emergency or manual shutdown• Parked (standing still or idling)• Parked and fault condition• Transport, assembly, maintenance and repair
