摘　　要：大型发电机定子绕组的故障放电是造成大型发电机损坏的重要原因。大型发电机定子绕组故障放电的识别，特别是如何有效地从强大的噪声干扰中最大限度不失真地抽取故障放电的特征信息，是大型发电机故障放电在线监测的技术关键。本文介绍了大型发电机定子绕组故障放电的原因、机理、危害、识别方法和抗干扰措施。The fault discharge of large generator winding is an important cause of damages. Recognition of fault discharge of stator winding, particularly extracting the characterizing information from the noise interference, is the key technique of monitoring the fault discharge of large generator stator winding on line. In this paper, the cause, mechanism, damages, monitoring methods, anti interference measurements and practical monitoring technologies of large generator stator winding fault discharge are introduced.
