摘　　要：本文考虑含静止同步串联补偿器(SSSC)的单机无穷大系统、汽门、励磁各变量间的相互作用建立了4阶多变量3输入3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3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仿真结果验证了该控制方法对发电机功角,机端电压和传输功率这3个控制指标有很好的控制效果.For the interactions between the single-machine-infinite-bus system with static-synchronous-series- compensator, the excitation and the stream valve control, we develop a 4th order nonlinear model with thi＇ee inputs and three outputs. This model is decoupled and linearized by using the dynamic inverse system theory to obtain three SISO pseudo linear systems; with them we design three SISO controllers by using the variable structure control theory. Simula- tion results on MATLAB show the feasibility and effectiveness of this control strategy in stabilizing the power-angle, the generator terminal voltage and the transmission power.
