摘　　要：由于PSS对于联络线上的低频振荡抑制效果不佳,所以有大量文献都提出采用SVC来抑制联络线低频振荡。根据SVC抑制低频振荡的原理,在电力系统仿真软件PSASP中搭建了SVC附加控制模型,在真实电网运行方式中仿真调试,来评估SVC对低频振荡的抑制效果,为大规模应用提出建议。Due to poor inhibitory effect of PSS for low frequency oscillations of contact line, a lot of literature have proposed the use of SVC to suppress low-frequency oscillation contact line. The SVC additional control model is built in the power system simulation software PSASP based on the principle of SVC to suppress low-frequency oscillations. A real simulation grid operation mode was simulated to assess the SVC to the inhibitory effect of low-frequency oscil-lations,and the proposals for large-scale applications was given.
