摘要(Abstract)：
晶闸管控制的可控移相器具有功率快速可控的特点,可用于提升故障后系统的阻尼水平。目前,可控移相器的研究主要集中在调节电网潮流方面,而用于提升系统阻尼方面的应用研究较少。在研究可控移相器附加阻尼控制方法的基础上,在PSS/E机电暂态程序中搭建可控移相器的自定义模型,基于华东电网数据模型,设计了以母线频率和线路功率作为附加阻尼控制输入的传递函数,比较了不同输入量对附加阻尼控制的效果。通过案例仿真分析得出:将线路功率作为附加阻尼控制输入信号的控制效果更优。
The thyristor-controlled phase shift transformer(TCPST) is characterized by fast power control,which can be used to raise the damping level in system fault. However, the present research on TCPST largely focuses on power flow regulation while rarely on damping improvement. Based on the research of additional damping control method for TCPST, modeling TCPST in PSS/E electromechanical transient software is accomplished. In east China power grid data model, transfer functions which take the bus frequency and line power as the input of additional damping control are designed, and the effects of different inputs on additional damping control are compared. Through case simulation analysis it is concluded that the control effect is better when the line power is used as the input signal of the additional damping control.
