摘　　要：从水轮发电机的状态监测现状出发 ,在研究总结水轮发电机常见故障模式及机理基础上 ,归纳了以实现电厂状态检修为目的的综合状态监测的监测内容、手段及诊断方法 ,提出状态检修信息系统中的水轮发电机状态监测与诊断系统 。The research and application status of the condition monitoring in hydrogenerators is described.Based on summarizing the basic failure modes and their mechanism of hydrogenerators, this paper concludes the contents and methods of condition monitoring as well as the diagnosis strategy. A condition monitoring and diagnosis system of hydrogenerator is presented to provide essential information to perform condition maintenance in hydro power plants. The structure and features of this system are also discussed.
