摘要(Abstract)：

大规模风力发电并网可能会引发严重的稳定性问题,例如与直驱风电机组有关的新型次同步振荡(subsynchronous oscillation,SSO)。这种新型SSO发生时通常伴随着显著的频率耦合效应,且该耦合现象在分析系统稳定性时有重要影响。为此,文章首先提出采用频率耦合阻抗模型(frequency-coupled impedance model,FCIM)分析直驱风电机组的频率耦合特性,之后建立了频率耦合阻抗模型测试平台,提出了频率耦合阻抗模型的辨识方法。然后基于平台和辨识方法得到了直驱风电机组的频率耦合阻抗模型,并根据所提方法拟合得到了阻抗模型传递函数。最后分析了直驱风电机组的频率耦合特性,可为电力系统振荡研究的模型选择提供参考。
