摘　　要：分析了TCSC的结构、运行模式及谐波特性，着重研究了TCSC对保护安装处电压的影响，对线路电流序分量相位的影响，以及TCSC谐波对距离保护的影响。认为稳态条件下，距离保护性能不受TCSC的影响；故障条件下，也基本不会降低距离保护的性能。The structure, operation modes and harmonic of TCSC are analyzed. The influence of TCSC on voltage of the node where distance protection relay is located and phase of line current sequence component as well as the effect of TCSC harmonic on distance protection relay are emphatically studied.It is concluded that TCSC has no effect on distance protection relay under normal condition. and under conditions of faults, the performance of distance protection relay will not be impaired by TCSC.
