How to model extreme wind shear

1. From the IEC standard

2. In SIMA

For special cases use Turbine Class S. Vref is not used for EWSV, and Iref is the expected value of hub height TI at a 10 min average wind speed of 15 min/s.

3. Environment in SIMA

The wind environment must have a power shear profile with wind shear exponent set to 0.2.

4. Wind at top of rotor
