13. Minimize Turbine Loads: Is this turbine good
for my site?
Demonstration that the wind conditions at the site are no more
severe than those assumed for the design of the wind turbine
(IEC 61400 – 1: Design Requirements)

14. Minimize Turbine Loads: Assessment of
structural integrity by reference to wind data
the following conditions should be checked at the site:
• Estimate of extreme 10-min average wind speed at hub height
with a recurrence period of 50 year
• Value of the probability density function of Vhub
• Environmental turbulence plus wake induced turbulence from
nearby turbines
• Average vertical wind shear
• Flow inclination
• Air density

15. Remote Sensing Correction
Elevation
• Correlation – LIDAR vs Mast
• 6.7% Averaged Relative Error
• Remote Sensing Correction Tool –> 0.3%
Vertical Wind Speed

16. Layout design and optimization
Drawn wind farm area
Check IEC constraints
Optimize layout according to:
- Annual Energy Production
- Net present value

17. Post construction assessment
Compare measured and expected wind Performance Matrix method used
farm power curve to check the
performance of your investment.
