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.
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。
