MEASUREMENT OF STRESS ON BLADE OF NEDO'S 500 Kw PROTOTYPE WIND TURBINE

摘要

Among the components used in a wind turbine the blade is the most damageable component for fatigue caused by atmospheric turbulence. Therefore it is necessary to understand the stresses which are occurring on the operating wind turbine blade. We instaled a prototype 500 kW wind turbine developed by the NEDO (New Energy and industrial technology Development Organization) in Tappi Wind Park where is very complex terrian, to study its performance, reliablity and durability. Some measurements and data analysis of the blade stress have been done. In this paper, some results of the stress measurement are presented.
