摘　　要：首先基于单机无穷大系统的数学模型建立了包括可控串补的状态空间描述;然后根据线性最优控制理论,应用基于次时间最优控制的加权矩阵确定方法设计了单机无穷大系统的可控串补控制器。采用上述方法不仅可以准确、快速地设计出所需要的控制器,还可避免设计者的盲目试验。最后利用PSCAD/EMTDC仿真程序,通过对含可控串补的单机无穷大系统的暂态仿真验证了该方法的有效性。In this paper, firstly based on the mathematical model of single-machine infinite bus system the state space description is built in which thyristor controlled series compensation （TCSC） is included; then according to linear optimal control theory, a TCSC controller for single-machine infinite bus system is designed by the determination of weighted matrix based on subtime optimal control. Using above-mentioned method not only the required controller can be designed, but also the blind trial by designer can be avoided. Finally, using PSCAD/EMTDC simulation software, by means of transient simulation of single-machine infinite bus system containing TCSC, the effectiveness of the proposed method.
