摘要(Abstract)：

局部放电在线测量和分析能有效监测发电机的绝缘状态,可早期诊断绝缘缺陷,避免突发性故障的发生。无线电射频监测和局放监测是目前主要的两种发电机局部放电在线监测方法,已被广泛应用。主要介绍SIEMENS局部放电监测系统信号测量、噪声抑制、故障定位等原理,分析了该系统的特点及在发电机中的应用。
On-line partial discharge measuring and analysis can monitor the generator's insulation effectively, thereby the insulation defect is diagnosed early, unexpected malfunction can be prevented. Radio frequency monitoring and partial discharge analyzer are two main on-line monitoring methods for generator partial discharge, which have been put into application widely. This paper mainly describes the principles of signal measuring, noise restraining, malfunction positioning in SIEMENS partial discharge monitoring system, and the characteristics and application in generator are analyzed.
