描述
2009年8月31日,现场检查时发现#5机#11 I/O站和#26 I/O站主控器故障,均为A主控故障灯闪亮,双机冗余通讯灯不亮,B主控备用。从工程师站上查看,主控制器显示A主控为主,B主控备用,状态显示正常;查阅DCS历史记录,无相关故障记录;相关I/O站内各参数采集、控制设备动作均正常。经分析,认为主控制器当前仍正常运行,但双机冗余的同步性存在问题,如果这时发生主控切换将会出现较大扰动。而在这之前异常控制器不能冗余切换故障已发生过多次,如#3炉DCS系统曾发生一次风压自动调节偏差大于36OPa时,运行人员手动干预操作送风机勺管调节执行机构无效,急忙至就地进行手操。热工通过工程师站,检查对应的#12 I/O站,发现A主控离线,B主控备用,在I/O站上查看A主控系统灯1和系统灯2均不亮,故障灯未亮,表明该主控已失去与系统网的数据交流,但主控未实现冗余切换。另#3炉#23 I/O站也曾发生过A主控故障离线,故障灯与双机冗余数据交换灯均不亮,主控制器未自动切换。这些故障案例表明,MACS系统主控制器冗余切换功能不完善,某种故障状态下该功能失效。
