Distributions of Daily Extreme Winds and Wind Turbine Operation

Two statistical distributions are fitted to a set of extreme wind data and the Fisher-Tippett Type I is shown to be superior. Daily extremes are examined for their influence on wind turbine operation. Formulas are given for converting annual extreme wind statistics to daily or monthly extremes. A daily extreme of 40 mph is experienced about 1 day out of 10 and 56 mph about 1 day out of 100 at 50 m in Kansas.
