摘　　要：随着我国电力系统的发展,串联电容补偿在输电系统的应用越来越广泛,但其引起的次同步谐振(SSR)问题也随之而来。针对输电网中串联电容补偿引发的次同步谐振,文章采用基于时域仿真实现的复转矩系数法分析了不同发电机出力以及不同串补度对系统次同步谐振的影响。仿真验证了故障情况下,较小串补度系统对次同步谐振的稳定性。With the power system development in China, series capacity compensation has been generally used in power transmission system, but it accordingly induced subsynchronous resonance （ SSR） problem. Aiming at this problem, the paper analyzes the influence of SSR under different generator output and different degree of series compensation through adopting complex torque coefficient approach based on time domain simulation. The simulation proves the stability of lower degree series capacity compensation on SSR.
