二、DCS在生产过程中的故障情况
每个厂家的DCS都有其各自的特点,因此其故障的现象分析和处理不尽相同,但归纳起来由DCS引起机组二类及以上障碍可划分为三大类:
(1)系统本身问题,包括设计安装缺陷、软硬件故障等。
(2)人为因素造成的故障,包括人员造成的误操作,管理制度不完善及执行环节落实。
(3)系统外部环境问题造成DCS故障。如环境温度过高、湿度过高或过低、粉尘、振动以及小动物等因素造成异常。
2.1 DCS本身问题故障实例
此类故障在生产过程中较为常见,主要包括系统设计安装缺陷,控制器(DPU)的脱网等故障,操作员站黑屏,网络通讯堵塞,软件存在缺陷,系统配置较低,与其他系统及设备接口存在问题等。
