针对可控串联补偿（ＴＣＳＣ）的动态包含离散动态和连续动态的特点，首先分析当ＴＣＳＣ运行状态发生改变时影响其动态过程的因素，认为ＴＣＳＣ的固有动态响应时间与可控硅导通时刻电容电压偏离稳态值的大小有关，因此可以假设ＴＣＳＣ的动态过程可以预测，并在仿真分析的基础上得出ＴＣＳＣ基频动态等值新模型。该模型内在地包含了可控硅触发逻辑和同步环节的动态。在暂态稳定计算程序中，ＴＣＳＣ被视为一个变阻抗，与电力系统网络接口良好，而且计算量增加不多，可以得到比较精确的计算结果。但该建模方法仅适用于ＴＣＳＣ在容性区域内运行。如ＴＣＳＣ从容性模式过渡到旁通模式，其动态过程用电流源模型来描述。
In view of the dynamic discrete dynamic and continuous dynamic characteristics of TCSC, the factors that affect the dynamic process of TCSC are analyzed first. The inherent dynamic response time of TCSC is compared with that of thyristor on-time Since the voltage deviates from the steady-state value, it can be assumed that the TCSC dynamic process can be predicted, and based on the simulation analysis, a new TCSC baseband equivalent dynamic model is obtained. This model inherently contains the dynamics of the thyristor trigger logic and synchronization. In the transient stability calculation program, TCSC is regarded as a variable impedance, good interface with the power system network, and the calculation of the amount of increase is small, you can get more accurate calculation results. However, this modeling method only works for TCSCs in capacitive areas. If TCSC transition from capacitive mode to bypass mode, the dynamic process of current source model to describe.
