【摘要】 介绍了晶闸管控制串联补偿电容（ＴＣＳＣ）时域仿真的数学模型和软件，就ＴＣＳＣ的动态特性进行了研究分析，结果表明，ＴＣＳＣ元件达到稳定运行的时间随触发角的增大而减小，其基频阻抗与线路电流无关，并就金属氧化物避雷器（ＭＯＶ）的模型提出了新型的动态电阻模型，更好地反映了ＭＯＶ的实际工作特性．更多还原

【Abstract】 The mathematic model and program of TCSC time domain simulation are described. TCSC dynamic characteristic is analyzed by simulation. The delay of TCSC settling into steady state operation decreases with the increase of trigger angle. Line current has no effect on TCSCs fundamental frequency impedance. New dynamic resistance model for Metal Oxide Varistor (MOV), which simulates MOVs realistic performance better, is also presented.更多还原
