换流阀BOD动作告警的异常与处理分析

Analysis of Abnormity and Handling of BOD Action Alarm of Converter Valve

阐述换流站换流阀解锁后,阀控系统触发晶闸管BOD动作告警异常,通过对换流阀晶闸管监视及BOD检测原理分析,结合现场检查试验,判定这是一起由阀控系统光收发板卡故障引起的误报警。

This paper describes the abnormal action alarm of thyristor BOD triggered by the valve control system after the converter valve of the converter station is unlocked.Through the analysis of the thyristor monitoring and BOD detection principle of the converter valve,combined with the on-site inspection test,it is determined that this is a false alarm caused by the fault of the optical transceiver card of the valve control system.
