We want to derive the peak coefficient for wind
turbines based on wind data per hour for the past 10 -20 years for different
regions offshore and onshore.
Some questions:
- Is it sufficient with data on an hour basis or is
data per 10 min required?
- Do you use the minimum wind speed value of the
past 20 years or do you select a representative year?
- If latter, how do you know if it is a
representative year?
- How do you handle the situation where the wind speed is below the operational area of the wind turbine (cut in speed)?
I assume that we will see that there is less
variation in the wind speed for offshore compared to onshore wind turbines.
Also, I assume that the peak coefficient differ if you model a small region, a
country or the world. Do anyone have an opinion on this?
I am grateful for all comments!
Thanks!
