摘　　要：为了解决某火电厂配煤系统不定期出现的配煤量跳变的异常问题,从分析控制程序入手,分析有关的外部输入信号在各种异常状态下控制程序可能出现的输出结果,并通过在实际运行程序中设置条件模拟故障原因来验证推断的方法查找故障原因,找出了引起故障的具体原因,经改进控制程序后再未出现过配煤量跳变的情况,有效解决了故障问题。In order to solve the problem of the irregular jump of coal blending amount in the coal blending system of a thermal power plant,an analysis of the control program was carried out.Possible output results of the control program in various abnormal states with relevant external input signals were analyzed,and the fault cause was derived and verified by fault simulation.The problem of jump of coal blending amount was effectively solved following improvement of the control program.
