| 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。

| Abstract: | 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-bus system.Indicate that liner optimal excitation controller has more preferable control performance,and compare with AVR+PSS excitation controller has well dynamic performance,too. |
