摘　　要：以IEEE第一标准模型为研究对象,采用时域仿真的方法分别比较了固定串补电容、可控串联补偿(TCSC)以及电容和电感相并联的TCSC阻抗等效模型对该系统发生次同步谐振的影响,结果表明TCSC能够抑制该系统发生次同步谐振。采用基于时域仿真的复转矩系数法[2]分析了3种情况下发电机侧的等效电气阻尼特性,发现TCSC引起了电气阻尼的巨大变化,并对TCSC抑制次同步谐振的机理作了初步分析。In this thesis, time domain simulation is used to compare the impact of fixed series capacitor, TCSC and LC equivalent impedance model on sub-synchronous resonance. The results of the simulation show that TCSC can mitigate sub-synchronous resonance. The Complex torque approach realized by time domain simulation is adopted to study the electrical damping characteristics in the three cases and the results show that TCSC causes the huge change of electrical damping characteristics. Finally, this paper discusses the mechanism of SSR Mitigation Using the TCSC.
