摘　　要：随着同步发电机组容量的增加,为防止发电机内部故障扩大,对发电机的灭磁系统提出了更高的要求。本文分析了交流灭磁和无源零开断自动灭磁两种灭磁方式,对大型同步发电机的灭磁系统应用做了一些展望。Along breakdown from with the synchronization power set capacity increasing, for prevent the generator interior expanding , the generator has a higher request to the de -excitation system. This article has analyzed the two de - excitation ways AC - excitation and Automatic excitation with no source and no current, also has made some forecasts to the de - excitation system application of large - scale syn- chronousgenerator.
