摘要(Abstract)：

基于传递函数的思想分析了次同步扰动下双馈风机系统的多频率响应。首先,基于次同步扰动信号的响应路径,将双馈风机系统分为受控异步机系统和网侧换流器系统。其次,基于次同步扰动信号在受控异步机系统内各环节的作用或响应流程,定性推导并分析了受控异步机系统各环节的频率响应,获得了异步机转子和定子的多频率响应。再次,基于次同步扰动信号在网侧换流器系统各环节的作用或响应流程,定性推导并分析了网侧换流器系统各主要环节的频率响应,获得了网侧换流器注入系统的各频率响应。由此,获得了双馈风机系统整体在并网点输出的电流多频率响应,揭示了次同步扰动下,双馈风机并入系统的多频率特性。最后,基于仿真验证了上述理论分析的正确性。
