摘　　要：在线性控制理论的基础上设计同步发电机的最优励磁控制器,基于Matlab编程的时域仿真验证,表明:设计的系统有良好的动态响应速度和阻尼特性,具备良好的静态和暂态稳定性.通过对最优励磁控制系统暂态稳定性的分析,验证增大强励倍数对提高电力系统暂态稳定性起到的积极作用;对于单机无穷大系统短路点距线路首端越远,该线路的极限切除时间越大.Optimal synchronous generator excitation controller is designed based on the linear con- trol theory. By Matlab time-domain simulation, the results shows the designed system has good dynamic response speed and damping characteristic. The waves also show the system has fine static and transient stability. And increasing strong excitation multiples plays a positive role for improving transient stability. In addition, the farther short-circuit dot is away from the head of line, the longer the limit clearing time is.
