Design and Development of Loads for the Final Wind Turbine

Abstract

This work discusses the need for a large number and long length of simulations to generate reliable load estimations, in addition to the inherent uncertainty in the simulation of loads using structural dynamics software. Loads data has substantial statistical variance, and we provide a methodology for extrapolation and quantile determination. In order to determine severe loads with a reasonable amount of uncertainty, it may be possible to further minimize the necessary numerical labor by using a stochastic process model for the dynamic reactions. We offer a method that allows for a non-Gaussian but nonetheless reasonably accurate answer. When everything is said and done, the turbine's extreme loads are computed accordance to the new IEC 61400-1 standard for safety regulations for wind turbines, and a comparison is made between loads derived from gust models and suitably extrapolated simulation extremes
