SEISMIC ANALYSIS OF WIND TURBINE SYSTEM
In this paper, the dynamic response of wind turbine system under earthquake action is numerically investigated. First, an integrated finite element (FE) model of wind turbine system consisting of the rotor, the nacelle and the tower is established. To evaluate the effect of the soil-structure interaction (SSI) on the dynamic performance of wind turbine system, a comparative FE model taking the foundation and surrounding soil into consideration is also created. Then, the time history analysis of wind turbine system under the input of El Centro earthquake record is carried out. The results show that the seismic response of wind turbine system is remarkable and may be the dominant factor in the design of wind turbine system located at seismically ac-tire zone. It is also found that apparent difference exists between the results from the model considering SSI effect and that from the model not considering SSI effect.
