摘　　要：针对电力系统的稳定性问题,设计了发电机励磁系统与可控串联补偿TCSC(thysistor controlled series compensation)装置的协调控制器。该方法从发电机励磁系统与TCSC模型出发,建立了含TCSC的单机无穷大系统的四阶非线性状态空间模型,利用非线性系统的微分几何理论,将其非线性模型精确线性化。在线性化模型的基础上,考虑电力系统运行参数的不确定性,采用滑模控制理论对发电机励磁系统与TCSC进行协调控制,通过指数趋近律和准滑动模态方法,最终获得了整个系统的滑模协调控制规律。单机无穷大电力系统仿真结果表明,所设计的协调控制方法对电力系统的扰动具有良好的适应性和鲁棒性,提高了电力系统的稳定性。In order to tackle the stability of power system problems,the coordinated control method of generator excitation and thyristor-controlled series compensation （TCSC） is proposed.The method is on the basis of the generator excitation system with TCSC model,via a single-machine-infinite-bus with TCSC system of fourth-order nonlinear state-space model.The nonlinear model can be linearized accurately by the method of differential geometry theory for nonlinear systems,and on the basis of this linear model,via exponential reaching law and quasi-slide mode method to obtain sliding mode coordinated control law of the whole system.The simulation of single-machine-infinite-bus system results indicate that,the design of coordinated controller for disturbances of system has good adaptability and robustness.
