Abstract

In this research, modeling and vibrations analysis of a Wind Turbine system including tower and blades is studied. Modeling of each blade of the Wind Turbine is considered to be as an elastic beam with rotational speed, and Wind Turbine tower is also modeled as an Euler-Bernoulli flexible beam. Lateral vibrations of the system (tower and blades) are considered in the plane of rotational of blades. The governing equations of motion of the Wind Turbine are derived by the Lagrangian approach by the semi-analytically method, and then governing equations are solved numerically. For the numerical solution, a limited number of elements are considered for the tower and the blades. After that, the natural frequencies of 2. 5 MW SAMEN Wind Turbine are investigated by using its technical specifications. The effect of variation of tower length, blades length, and the total mass of nacelle and hub on the natural frequencies behavior of the system are investigated. Finally, the Sensitivity Analysis of the Wind Turbine natural frequencies with respect to different values of system parameters is presented.
