    Con el propósito de desarrollar estrategias para el mayor aprovechamiento del recurso eólico, es necesario disponer de modelos confiables para simular la respuesta de los aerogeneradores. Si bien, los fabricantes cuentan con modelos detallados, estos son generalmente de “caja negra”, lo que los hace incluso inutilizable en nuevos diseños. Así, los llamados modelos genéricos han proliferado. Bajo este enfoque, en este artículo se presenta el modelado dinámico del rotor de un aerogenerador tripala usando la formulación Euler-Lagrange. Para su análisis el rotor es descrito como un sistema multicuerpo de cuatro grados de libertad empleando matrices de transformación simplificadas. Se exponen los detalles de la obtención del modelo, y la interpretación de su simulación tridimensional (3D) bajo diversas condiciones, que garantiza una fácil comprobación de la fiabilidad del modelo.

    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.
