摘　　要：将SSSC考虑为输电线路上的可变阻抗,将其同含有汽门控制的单机无穷大系统联立为三阶多变量两输入两输出非线性模型,在此模型基础上,运用动态逆系统方法完成解耦和线性化,构造出两个单输入单输出的伪线性系统,并采用变结构控制理论分别设计控制器。根据Matlab仿真结果验证了该方法对发电机功角,传输功率这两个控制指标有很好的控制效果。According to viewing SSSC as a variable series impedance, the paper established three orders nonlinear model which is two input two output system, including the single machine infinite bus system and stream valve control. Based on the model the dynamic invert system theory was used to cope with the coupling and linearization, then variable structure control iwas employed for the two SISO pseudo linear systems. Finally, The results of MATLAB proved the viability and effectiveness of the control strategy which aim at the stability of power-angle and transmission power.
