摘　　要：该文设计了一种TCSC自适应Terminal滑模稳定控制器,以提高互联电力系统的稳定性。文中建立了含TCSC的两机电力系统的数学模型;控制器设计应用了Terminal滑模控制理论,使误差能够快速收敛,从而取得良好的控制效果;设计中考虑了阻尼参数的不确定以及外扰动的影响;利用MATLAB进行了两机系统的仿真。仿真结果表明,所设计的TCSC自适应Terminal稳定控制器能够快速阻尼功率振荡,提高互联电力系统的稳定性,且效果优于基于逆推法设计的TCSC稳定控制器。An adaptive terminal sliding mode controller for TCSC is designed in order to improve the stability of interconnected power systems. A mathematical model of two-machine power system with TCSC is established. Terminal sliding mode control theory is applied to controller design, so that the fast convergence of errors can be realized to achieve good control effect. The impacts of uncertainty of parameters and external disturbances are also considered during the controller design. The simulation results of two-machine system using MAT- LAB show that the terminal sliding mode controller can damp power oscillation quickly and improve the stability of interconnected power systems, and the effect is better than the baekstepping controller.
