摘　　要：文章建立了风力机、异步感应发电机、桨距角控制系统的数学模型并给出了对应的微分方程。通过分析异步风电机接入传统电力系统特征根和振荡模式,研究了接入异步风电机多机系统的小干扰稳定性。得出全风况条件下系统特征根的轨迹图并对相应的振荡模式进行分析,给出了各特征根的主要参与因子。In this paper, the models and the linear cquations of state of wind turbine, asynchronous induction generator and pitch angle system are built. By analyzing eigenvalues and oscillation modes, small-signal stability of power system with asynchronous induction generator is studied. Root locus, main participation factors of eigenvalues as well as oscillation modes under different wind speed conditions are obtained.
