摘　　要：ＴＣＳＣ的动态基频阻抗特性分析对研究含ＴＣＳＣ线路上的线路保护的特性具有重要意义。采用数值仿真分析的方法，详细研究了ＴＣＳＣ动态基频阻抗与滤波器、触发角、故障条件下ＴＣＳＣ是否旁路、短路时刻及短路地点等多种因素的关系，认为在选定滤波器的条件下，ＴＣＳＣ对故障的应对方式是影响动态基频阻抗变化规律的最重要因素。The dynamic power frequency impedance of TCSC is of great importance to the analysis of protective relaying characteristics on transmission line with TCSC.By digital simulation,this paper studies in detail on the relationship between TCSC dynamic power frequency impedance with filter,firing angle,TCSC's bypass,fault time and fault location when a short circuit fault occurs on transmission line with TCSC.It is concluded that with the selected filter,the response of TCSC to fault has the most important effect on the change of TCSC dynamic power frequency impedance.
