    Abstract: The control system of five coal feeders of No. 300MW unit ofZhangjiakou Thermal Power Company has been put into operationfor ten years, the plates are gradually aging, and the failure rate ishigh. In addition, the original Coal Feeder Control System programsolidified in the memory cannot be seen after the failure cannot beaccurately judged. In view of these problems, the control system of coalfeeder is upgraded. In this paper, the problems and solutions after thetransformation process and put into operation are described. The resultsshow that the coal feeder control system runs stably and achieves theexpected upgrading effect.

    Key words: Coal feeder, PLC; Control system; Automatic regulation
