| 摘要: |
| 分析了可控串补TCSC(Thyristor Controlled Series Compensation)分别以电容电压和线路电流为同步信号，在容性微调区从高补偿区向低补偿区及反方向阶跃跳变时。基频阻抗的暂态变化过程。研究了在不同同步信号下，感性区和容性区相互转换时TCSC的暂态特性，指出从容性区转换到感性区以及从感性区转换到容性区阻断模式时，两种同步信号下的暂态过程相似：但由感性区转换到容性微调区时，电容电压同步信号下需先将TCSC切换到阻断模式，待进入稳态后再调节补偿度，而线路电流同步信号下则可直接进行。 |

| Abstract: |
| Respectively with capacitive voltage and line current as the synchronization signal,the transient impedance characteristics of TCSC(Thyristor Controlled Series Compensation)during step change from high compensation to low compensation of the capacitive vernier region or vice versa are analyzed. The transient characteristics of TCSC during transitions between inductive region and capacitive region under different synchronization signals are studies. During the transition from capacitive region to inductive region or from inductive region to capacitive block mode,the transient processes under both synchronization signals are similar. However,during transition from inductive region to capacitive vernier region,it is necessary for TCSC under capacitive voltage synchronization signal to transit first to block mode and then adjust the compensation degree after steady,while under line current synchronization signal,it is not neccessary. |
