摘    要:针对需要对每个火电厂自动配煤系统单独编写控制程序存在工作量大的问题,介绍了一种通用的配煤控制程序的设计;以犁煤器为控制对象,通过找出影响其抬起和落下的关联条件,设计出了通用的PLC功能块。实际应用表明,设计的程序可移植性和可扩展性强,可靠性高,节省了输煤程控系统的编程时间和调试时间。

关 键 词:火电厂  煤仓  配煤系统  控制程序  犁煤器  PLC

Abstract:In view of problem of bigger workload because of needing write control program individually for each automatic blending system of thermal power plant,the paper introduced design of a general coal blending control program.Taking coal plough as control object and finding association condition influencing on lifting and falling of coal plough,it designed general PLC function block.The actual application showed that the program has strong portability and expansibility and high reliability,which saves time of pr...
Keywords:thermal power plant  coal bunker  coal blending system  control program  coal plough  PLC
