摘　　要：针对直驱风电系统,建立了控制器理想输出时永磁直驱风电系统的非线性模型,分析了研究系统稳定性的必要性。并阐述了系统稳定性分析主流方法的利弊,在此基础上提出了一种基于数值算法的扰动稳定性分析法,并用仿真获得了系统的受扰动稳定域。ABSTRACT：This paper establishes the nonlinear model of the directly driven permanent magnet wind power system assuming the output of the controller is ideal,and examines the necessity to study the system stability. The paper also expounds the advantages and disadvantages of the mainstream method for the system stability analysis. On this basis,the paper presents a disturbance stability analysis based on the numerical algorithm and the disturbance stability region of the system is obtained through simulations.
