通过计算机数值仿真和动模实验研究，提出了不同同步信号及电路参数对可控串补（TCSC）的动态工作特性及控制精度的主要影响。从等效的概念上分析了TCSC的动态阻尼特性。得到了采用闭环控制方式可缩短阻抗调节时响应时间的结论。研究表明，合理选取同步信号和采取特殊的硬件Block和Bypass控制模式，可有效减小各种干扰，实现TCSC三相运行时工作区域的快速过渡跳变和稳定运行，缩短了动态调节的响应时间，有效地消除了系统故障后的直流分量，提高了暂态稳定控制特性。
Through computer numerical simulation and dynamic model experiment, the main influence of different synchronization signals and circuit parameters on the TCSC dynamic performance and control accuracy are proposed. The dynamic damping characteristics of TCSC are analyzed from the concept of equivalence. The conclusion that the closed-loop control method can shorten the response time when the impedance is adjusted is obtained. The research shows that the reasonable selection of synchronization signals and the special hardware Block and Bypass control modes can effectively reduce various interferences and achieve fast transition transition and stable operation in the working area of TCSC three phase operation and shorten the response time of dynamic adjustment , Effectively eliminating the DC component of the system failure and improve the transient stability control characteristics.
