摘　　要：可控串联电容补偿（TCSC）动态基频阻抗特性对距离保护的影响与固定串联电容补偿（FSC）对距离保护的影响在主要方面是相似的，电压反向及电压互感器、电流互感器位置的选择同样是影响保护性能的关键因素，但电压反向、动态特性的变化、保护范围及动作速度等方面也存在差别。在FSC线路上能运行的距离保护在TCSC线路上仍然能很好地运行。The influence of TCSC dynamic power frequency impedance on distance protection relay is similar to that of FSC.Voltage inversion and location of potential transformer and current transformer are also the key factors for TCSC to influence the performance of distance protection relay. But there still exist some differences between TCSC and FSC about voltage inversion, variation of dynamic characteristic. protection range and tripping time. The distance relays with good per formance on transmission lines with FSC will also have good performance on lines with TCSC.
