摘　　要：文章针对2012年5月2日龙泉换流站发生的极Ⅱ直流系统突发强迫停运事件,对换流站监控系统事件信息、故障录波信息、闭锁信号来源、信号传输过程以及直流控制保护系统软件等方面进行了分析,判断故障原因为:直流控制保护B系统主机MC1的PCIB板或PCI总线出现瞬时性异常,导致换流变非电量保护Z闭锁信号从PCIB板传输到CPU板时出错。针对故障原因提出了相应建议。On May and, 2012 the shutdown incident of pole 2 DC system suddenly occurred in Longquan converter station. The information from monitoring system, fault recorder and DC control and protection system was analysed. The PCIB plate or PCI bus in DC control and protection B system was suspected abnormal. The relevant proposal was put forward as well.
