摘要
随着水轮发电机组单机容量的增大,其安全经济运行显得尤为重要。而常规的监测系统不能满足现代化水电厂实行状态检测、预知维护的需要。主要叙述了水轮发电机局部放电在线监测系统设计,包括局部放电信号的监测系统原理、监测系统的结构和软硬件的构成。
With the unit capacity increase of hydroeleetric generating set, its safe and economic operation appears even more important. But common monitoring systems can't meet the need of the condition maintenance and predictive maintenance in modem hydropower station, so the design of on- llne monitoring system for partial discharge of hydro- generator are mainly described, including the monitoring system theory of partial discharge signal, the structure of monitoring system and the composition of software and hardware.
