大功率整流装置故障监测与诊断

介绍了如何利用网侧交流有效值来监测和诊断大功率整流装置的故障,并判断出是整流装置的硬件故障,还是整流控制器的故障.若是整流装置的硬件故障则给出报警,然后封锁触发脉冲和跳高压开关,以免事故进一步扩大;若是控制器故障,则微扰动切换到备用的控制器.重点给出了大功率整流装置在缺臂状态下,判断整流装置故障的一些条件,并叙述了如何利用可编程逻辑控制器(Programmable Logic Controller,简称PLC)实现备用控制器的自动投入和故障控制器的解除的方法.

Monitoring and Fault Diagnosis of High Power Rectifier

This paper introduces how to monitor and diagnose the rectifier using Alternative Current Root of Mean Square(AC-RMS),and confirms the fault in rectifier or in controller.To the fault of the hardware of rectifier,the Programmable Logic Controller(PLC) closes the trigger pulse and cut off the High Voltage(HV) breaker,but to the fault of the controller,the PLC switchs to the standby controller with no-disturbance.How to launch the standby controller automatically after relieving the fault controller is introduced.
