Dynamic Modelling of the Rotating Subsystem of a Wind Turbine for Control Design Purposes

The present work reviews the dynamic models for the rotating subsystem of a wind turbine, which have been developed for control purposes in the literature. Modelling approaches are systematically organized and classified including advantage, drawbacks and limitations. Based on the 5-MW reference turbine developed by NREL, analysis and simulation studies for some of the presented models are carried out. Hence, it is possible to determine modelsâ properties in time domain, sampling time, computational burden of time discrete models. Finally, recommendations for the selection of a model according to the application are given.
