摘　　要：基于单机无穷大系统的线性化模型,结合线性最优控制理论建立了最优励磁控制器用的系统状态方程,求出线性最优励磁控制电力系统稳定器,用Matlab仿真软件在单机无穷大系统两种不同的运行状态下进行仿真,结果表明最优励磁控制具备了良好的电压性能,且给出了比AVR+PSS更强的阻尼,表现出良好的动态特性。Based on the linear model of single-machine infinite-bus power system and the theoretic of linear optimal control, a set of state space equations by linear optimal excitation controller are built. Then the optimal power system stabilizer is obtained. The Matlab simulation results on two operation points of single-machine infinite-hus system. Indicate that liner optimal excitation controller has more preferable control performance, and compare with AVR ＋ PSS excitation controller has well dynamic performance ,too.
