Abstract

An analysis was performed to determine the risk posed by wind turbine fragments on roads and buildings at the National Wind Technology Center at the National Renewable Energy Laboratory. The authors used a previously developed model of fragment trajectory and took into account the wind speed/direction distribution at the site and the probability of rotor failure. The site‐specific risk was assessed by determining the likelihood of impact and related consequences. For both the roads and buildings, the risk varied from low to routine, which was considered acceptable.

Comments

The authors would like to thank Lee Jay Fingersh at the NWTC for providing the CART turbine data and some insight into the problem, along with Sheri Anstedt at NREL for editorial assistance.
