摘　　要：介绍了目前核电站的主流发电机励磁系统模型,通过对幅频特性的研究,指出此种系统存在的不足。因而推荐带电流负反馈的高起始系统,通过分析证明其性能稳定并能有效提高响应速度。同时还简要概述了其相关的特性。The excitation system for generators in nuclear power plants currently is introduced. Shortcomings of this system are pointed out through the study on its amplitude-frequency characteristics. A high initial response system with current negative feedback is recommended through analysis, the system is able to keep stable and increase the response speed.Meanwhile,other related characteristics of it are briefly summarized too.

关 键 词：励磁系统 电流负反馈 高起始 幅频特性
