As the support structure of wind turbine, the tower bears alternating loads of wind when the wind turbine runs. To ensure the reliability of the wind turbine, it's necessary to carry out modal analysis on the tower, and this would prevent the natural frequency of the tower close to the rated speed of wind turbine. In this paper, finite element analysis of the tower is solved using ANSYS, and the natural...
In order to fully understand the characters and working principles of non-grid-connected wind turbine, this paper makes an analysis on different methods for modeling non-grid-connected wind turbine. First, according to the structure of the wind turbine, a theoretical model is presented, including three subsystems: rotor, transmission system and generator. Response of the model to a wind sequence is...
