摘　　要：文章以异步风力发电机组的动态模型为基础,在Matlab/Simulink中进行仿真和量测,得到相关稳态运行数据。通过参与因子的计算,分析了不同振荡模态与系统的动态过程之间的对应关系,通过特征根灵敏度的计算,得到了不同系统物理参数对相应振荡模态的影响,得到的分析结果与参与因子的分析结果是一致的,这些分析结果对进一步提高并网的异步风力发电机组的动态稳定性具有一定的参考价值。Based on the dynamic model of wind turbine with asynchronous generator, steady-state operating data is obtained through the simulation and measurement in Matlab/Simulink. The corre-spondence relationship between different oscillation modes and different dynamic process are devel-oped through the caculation of participation factors, the impacts of different physical parameters corresponding different oscillation modes are also obtained through the caculation of eigenvalue sensitivity. These two results are mutually consistent. These results provide reference value for im-proving the dynamic stability of gTid-connected asynchronous wind power generation system.
