摘    要:在分析了TCSC的基本特性的基础上,分析了TCSC对故障分量距离保护的影响,综合考虑故障TCSC旁路和不旁路2种情况,整定阻抗设为(Zad—jXc),并在此整定阻抗下,对故障分量距离保护在TCSC线路上的动作行为进行了分析,认为:故障分量距离保护在区外和反方向故障时不会误动作,但正向保护范围缩小了,在TCSC旁路时缩小更大。

关 键 词:可控串联补偿  故障分量距离保护  故障分量距离继电器  继电保护

Abstract:Based on the characteristics of TCSC, the influence of TCSC on fault component resistance protection is analyzed. With the new setting resistance to be Z_(Zd)-jX_C, the action of fault component resistance protection on the line equipped with TCSC is presented. It is concluded that the fault component resistance protection will not act incorrectly, but the range of protection will be reduced, especially when the TCSC is bypassed.
Keywords:TCSC  fault component distance protection  fault component distance relay  relay protection
