摘　　要：针对部分地区新能源汇集站存在阻尼较弱问题,由汇集站调相机附加阻尼抑制弱系统低频振荡。首先给出、并建立含调相机的阻尼控制小干扰模型,分析模型的有功和无功关联特性,然后设计具有低频振荡抑制功能的调相机附加阻尼控制策略,最后建立含调相机的四机两区域仿真模型,利用时域仿真法验证调相机附加阻尼抑制低频振荡的有效性。To solve the weak damping problem in new energy collection stations in some areas,condensers are adopted to provide additional damping to suppress the low frequency oscillation in weak power grids.A small disturbance damping control model with a condenser is established.The correlation characteristics of the active and reactive powers of the model are analyzed.Then,the additional damping control strategy of the condenser with the low frequency oscillation suppression function is designed.A four-unit two-area simulation model with a condenser is constructed and the time-domain simulation method is adopted to verify the effectiveness of the proposed additional damping of the condenser in low frequency oscillation suppression.
