摘　　要：在分析可控串联电容补偿器TCSC(Thyristor-ControlledSeriesCapacitor)的运行模式、故障后的动作行为和动态基频阻抗特点的基础上,对比常规串联电容补偿器FSC(FixedSeriesCompensa鄄tion),分析了TCSC对距离保护、方向元件及纵联保护的影响,认为:与FSC的线路相比,在TCSC线路上保护的性能不会降低,在FSC线路上运行的保护,可以在TCSC线路上很好地运行。s:Based on the analysis of running mode,action after fault,dynamic power frequency impedance of TCSC(Thyristor-Controlled Series Capacitor) and compared with FSC(Fixed Series Compensation),the influence of TCSC on distance protection,direction component and pilot protection are analyzed. Protective relaying for lines with FCS may run well on lines with TCSC,and its protective performance will not become worse.
