摘　　要：在高压线路上装设可控串联补偿电容器(TCSC)可以改善系统的暂态稳定性,提高线路的传输容量。利用逆推方法与L2性能准则相结合,设计了多机系统TCSC非线性鲁棒控制器,该控制器可以抑止干扰对系统输出的影响。设计过程中不需要线性化和求解Riccati矩阵不等式,因此基于该方法的设计过程简明,易于为工程设计人员所接受。仿真表明该控制器能够维持闭环系统的渐近稳定。Thyristor controlled series compensation (TCSC) is expected to be applied in higher voltage lines to achieve much benefit such as improving the transient stability and enhancing the power transfer capability of long interconnected transmission lines. The controller based on backstepping method and L2 performance norm for the TCSC in multi-machine system is presented. The controller can attenuate the influences of external disturbances on system output. It need not to find the solution of Riccati matrix inequality in designing controller and make the controlled system linearized, so the design procedure based on this method is simplified. It is believed that this method can be accepted easily by engineers. The simulation results show that with this controller asymptotic stability of closed loop system can be met successfully.
