摘　　要：通过在PSCAD中建立IEEE First Benchmark进行仿真,分析了FSC和TCSC的SSR特性。针对两者不同的特性,建立TCSC次频阻抗特性分析模型,重点分析TM4不稳模式,详细解释了TCSC抑制SSR的原因。基于TCSC的阻抗特性可以抑制SSR,进行了FSC+ TCSC的仿真实验,发现选择合适的参数可以使FSC+ TCSC的串补装置抑制SSR。With simulation in IEEE First Benchmark using PSCAD, SSR characteristic of FSC and TCSC was analyzed. For the two different characteristics, one model for analyzing sub-synchronous frequency impedance characteristic of TCSC was proposed in the paper. Focusing on model TM4, the reasons for TCSC damping SSR was explained in detail. Based on the TCSC impedance characteristics, one FSC ＋ TCSC simulation was made. It was found that this series compensation can damp SSR if choosing suitable parameters.
