Extreme wind speed

Extreme wind speed is a term used in electricity production by Wind Turbines (WT). Highest average wind speed, averaged over t seconds, that is likely to be experienced within a specified time period of N years ("recurrence period”: N years)

In this standard recurrence periods of N = 50 years and N = 1 year and averaging time intervals of t=3 sec. and t=10 min are used. In popular language, the less precise term "survival wind speed” is often used. In this standard, however, the WT is designed using extreme wind speeds for design load cases.
