Modelling and Power Estimation of a New Method for the Extraction of Wind Energy

A new conceptual method is introduced in order to extract wind energy using a set of airfoils and a linear generator. Indeed, the idea of this method is inspired by the ocean wave energy extractor, and the linear wind generator. In this method, under wind velocity a mover connected to the airfoils undergoes a linear reciprocating motion such that this motion is converted to electricity using the magnetic field of a linear generator. Moreover, the structure and mechanism of the proposed method is illustrated. Based on this illustration, a perfect kinematics and kinetics analysis of the mechanism including of the displacement, velocity, acceleration, force and mechanical powers is done. Finally, the average generative power based on the proposed method is investigated under different conditions and compared to the output power of the ocean energy extractors in similar situations. The most important advantage of the proposed method in comparison with two mentioned methods is its simplicity, high efficiency and compatibility to all wind situations
