如今在我国大型火电机组中比较普遍地采用电子称重式给煤机,其控制系统多为单片机或者PLC进行控制,在日常的运行中发现此两种控制方式故障率较高,同时当故障出现时无法快速准确的处理故障.而将给煤机转入DCS系统进行控制则可以解决上述问题,DCS控制系统具有功能强大,组态简单,故障记录齐全的特点正是目前给煤机控制系统所需要的.%Today China's large-scale thermal power units mostly use electronic weighing coal feeder, and its control system mostly is SCM or PLC control. In the daily operation, the two control modes have high failure rate, and it is unable to quickly and accurately process the fault when a fault occurs. If the coal feeder is transferred to the DCS control system, the above problems can be solved. DCS control system has the features of powerful functions, simple configuration and complete fault recording, so it is necessary for coal feeder control system.
