摘　　要：研究了含有晶闸管可控串联补偿(TCSC)的单机无穷大电力系统的暂态稳定性问题。应用Backstepping设计方法设计了非线性控制器,并通过引入一个辅助系统和Nussbaum增益函数解决了系统输入量幅值约束问题。所设计的控制器在保留原系统的非线性特性的同时能使系统的输入增益保持在约束的范围内。仿真结果验证了该方法所设计的控制器的有效性。The problem on the transient stability of the single machine infinite bus system with Thyristor Controlled Series Capacitor （TCSC） was studied. Backstepping method used, the nonlinear controller was designed. An auxiliary design system and Nussbaum gain functions were introduced to address the problem of input constraint. In the design process, the nonlinear characteristics are kept completely and the control input is in the constraint. The simulation results show the effectiveness of the proposed method.
