摘要(Abstract)：

提出了含有TCSC装置的电力系统仿真的原理和方法。仿真研究表明，TCSC的等间隔触发控制策略［2］，能有效地提高系统的动态性能，过冲小且更快地趋于稳定。仿真研究还表明，采用电容电压过零时刻为基准的触发控制方式比以线路电流过零时刻为基准的控制方式具有更好的阻尼系统振荡的性能。这一点在以往许多研究文章中，由于采用电流源作为其分析TCSC动态特性的基础，而没有被揭示。
A program to analysis of AC system incorporating detailed model of TCSC has been developed. Itrevealed that the dynamics can be greatly improved with the new proposed equidistant firing control scheme.The analysis also revealed that a more significant improvement in system damping may be obtained when firingis synchronized to zeros of the voltage across the TCSC, compared to synchronized to zeros of line current. Thecharacteristic has not been revealed in present papers which analyze the TCSC dguamics based on currentsource medel.
