摘　　要：本文针对双馈风机经串补送出系统的次同步谐振问题,引入了电池储能附加阻尼控制来抑制风电场次同步谐振。首先分析了电池储能系统的常规控制策略,并建立了含电池储能的双馈风电场经串补送出系统的小信号模型,然后采用特征值法分析了系统次同步谐振模态和相关参与因子,以此为基础设计了具有次同步谐振抑制功能的电池储能附加阻尼控制策略,最后建立了含电池储能附加阻尼控制的双馈风电场经串补送出系统的PSCAD电磁暂态仿真模型,利用时域仿真法验证了电池储能附加阻尼控制抑制风电场次同步谐振的有效性。In view of the subsynchronous resonance problem of the DFIG-based wind farm interfaced with series compensation system,in this paper,the battery charging supplementary damping control is introduced to suppress the subsynchronous resonance of the wind farm.Firstly,the conventional control strategy of battery charging system is analyzedand the small signal model of doubly-fed wind farm with battery charging is established.Then the eigenvalue method is used to analyze the system*s subsynchronous resonance mode and related participation factors.Based this basis,a battery charging supplementary damping control strategy with subsynchronous resonance suppression is designed.Finally,the PSCAD electromagnetic transient simulation model of the DFIG-based wind farm with battery charging interfaced with series compensation system is established.The time domain simulation method is used to verify the effectiveness of the battery charging additional damping control to suppress the subsynchronous resonance.
