Abstract
In order to develop strategies to maximize the utilization of wind power, it is necessary to have reliable models to simulate wind turbines’ responses. Manufacturers have detailed models, though these are “black box”, which makes them unusable even in new designs. Thus, so-called generic models have proliferated. Under this approach, this article presents dynamic modeling for a three-bladed rotor in a wind turbine using Euler-Lagrange formulation. For this analysis, the rotor is described as a multibody system with four degrees of freedom using simplified transformation matrices. The details of how the model was obtained and the interpretation of its three-dimensional (3D) simulation are presented using diverse conditions, which guarantees that the model’s reliability can be easily verified.
