摘　　要：针对某重水堆核电厂备用柴油发电机AVR820励磁系统在起励建压过程中发生电压失控引起过电压停机的事件,展开了故障分析,确定原因是脉冲发生装置因整流桥失控、同步电压扰动而误触发脉冲,并提出了设计阻容滤波器和安装续流二极管的整改方案。In this paper,the accident of over-voltage shutdown caused by voltage out of control in the process of excitation of the standby diesel generator AVR820 excitation system in a heavy water reactor nuclear power plant is analyzed.The reason is that the pulse generator false triggering pulses due to the control failure of bridge rectifiers and the disturbance of synchronous voltage.A rectification program of designing a RC-filter and installing freewheeling diode is proposed.

关 键 词：起励 同步电压 触发脉冲 阻容滤波
