摘　　要：双馈感应发电机与输电线路串联电容补偿之间的次同步控制相互作用(SSCI)是引发双馈风电交流并网系统次同步振荡(SSO)的主要原因。该文通过建立双馈风电交流并网系统的阻抗模型,分析风电机组不同控制参数对系统SSO的影响程度,提出一种可等效电流环控制参数调整且兼顾基频控制性能的附加阻尼控制方法。为提升对振荡模态迁徙的适应性和鲁棒性,进一步将实时测频与模糊控制相结合,形成一种可根据振荡频率自动调整附加阻尼控制参数的SSO自适应抑制策略。最后,基于Matlab/Simulink仿真平台,验证该文所提出的SSO自适应抑制策略的正确性与有效性。The sub-synchronous control interaction(SSCI)between the doubly-fed induction generator(DFIG)and the series com-pensation capacitor(SSC)of the transmission line is the main reason for the sub-synchronous oscillation(SSO)of the dou-bly-fed wind power AC grid-connected system.By establishing the impedance model of the doubly-fed wind power integration system with SSC,this paper analyzes the influence of different control parameters of the wind turbine on SSO,and proposes an additional damping control method that is equivalent to the adjustment of current loop parameters and take into account the fundamental frequency control perfor-mance.In order to improve the adaptability and robustness to the oscillation mode migration,this paper further combines real-time frequency measurement with fuzzy control to form an adaptive suppression strategy that can automatically adjust additional damping control parameters according to the oscillation frequency.Finally,based on the Matlab/Simulink simulation platform,the correctness and effectiveness of the adaptive suppression strategy proposed in this paper are verified.
