摘　　要：选择交流励磁机系统IEEE—AC2A模型与静态励磁系统IEEE—ST1A模型进行仿真研究，仿真结果表明系统受大干扰后，静态励磁系统在抑制功角摆动、维持发电机机端电压和维持系统频率的能力上优于交流励磁机系统，为励磁系统建模，励磁系统选型，励磁系统大干扰稳定性分析等相关研究工作提供了可借鉴的经验。This article chose IEEE - AC2A model of AC exciter system and IEEE - ST1A model of static excitation system to do simulation. Sum up that static excitation system was better than AC exciter system in inhibiting swing of power - angle, maintaining terminal voltage of generator, maintaining system frequency when large disturbance oeeurod. Some quotable experience for excitation system modeling and selection were provided.
