摘要	The dynamic characteristics and response of wind turbines can be changed by the variation of soil characteristics and rotational velocity of blades. Based on the 2 MW three-blade horizontal axis wind turbines in Northwest wind farm, the model of wind turbine is established by using ANSYS software, considering the influence of blade rotation and soil-structure interaction on the dynamic characteristics of wind turbine, the wind turbine is studied in different working conditions (different blade rotational speed, different site conditions and both), and uses Campbell diagram to analyze the resonant characteristics of wind turbines under these conditions. The results show that the vibration frequency of wind turbines increases with the increase of blade speed, the coupling deformation of the cylinder and the blade increases the frequency; Considering the soil-structure interaction, the frequency of the wind turbine is reduced and the frequency of the soft wind generator is smaller. When the two working conditions work together, the blade rotation only affects the first order frequency, it has little effect on high order frequency, and the frequency of wind turbine is lower, considering that the wind turbine does not produce resonance point in 1P rotating frequency, the resonant point of the first order frequency in 3P rotating frequency is 14 r•min-1. In addition, the resonant points of wind turbines are generated in different sites, and the resonant frequencies of three kinds of soils are far away from the rated frequency. Therefore, in the field selection, structure design and daily operation of Wind farm, it is necessary to pay attention to its dynamic characteristic change, so that its frequency is far away from the resonant region and provide guarantee for the safe operation of wind turbines. © 2021, Solar Energy Periodical Office Co., Ltd.
