MODERN CONCURRENT APPROACH FOR WIND TURBINE DRIVETRAIN DYNAMICS AND DURABILITY PREDICTION

摘要

The wind energy industry continually evolves, and industry professionals have streamlined drivetrain design to a consensus configuration. This configuration and its design iteration have existed for many years; consequently, design and manufacturing flaws have been minimized sequentially. Regardless of the maturity of the drivetrain design and design process, however, most wind turbine downtime is attributed to gearbox-related issues. Moreover, driveline replacement and lubrication accounts for 38% of the parts cost of the entire turbine. The authors present an approach to modeling and simulation of the dynamic/life behavior of drivelines in wind turbines, based on practical experience gained in research projects related to the previously mentioned aspects. The following steps involved in the dynamic/life simulations of the wind turbine drivelines are explained by the following: -Finite Element model updating of a full wind turbine, with the accent on the driveline model by component level correlation, and system level operational correlation; -Comparative approaches for accurate drivetrain loads determination/application; -Damage/Life prediction calculation applied to drive train components.
