Dynamic Analysis of Wind Generators

Ming-Hung Hsu

Abstract

Wind power does not make any pollution and it also create a recyclable energy. The wind blade speeds significantly affect the measured output power. It is necessary to keep the wind blade tip speed to obtain maximum power. The wind blade speeds significantly affect the energy losses and the power coefficients. It is required to keep the wind blade tip speed to obtain the maximum power coefficient and minimum energy loss. The dynamic problems of the wind turbine generators are formulated by employing the differential quadrature method. The Euler-Bernoulli beam model is used to characterize the wind turbine generator blade. The differential quadrature method is used to transform the partial differential equations that present the dynamic behavior of the wind turbine generator blades into a discrete eigenvalue problem. The results show that the rotation speed could affect the frequencies of the wind generators. The inclined angle could not affect the frequencies of the wind generators significantly.
