摘要
目前火电厂输煤程控的一般实现方式为基于现场总线技术的PLC控制,而广州珠江电厂输煤程控则在此基础上增加了以太网技术应用,节约了成本,提高了可靠性和开放性。该文对其实现方式予以简要介绍。
PLC control, based on the fieldbus technique is usually used for realizing program control of coal conveying in power plants; but in Guangzhou Zhujiang Power Plant the Ethernet technique is being used in addition, wherewith costs are reduced and reliability as well as accessibility promoted. The paper presents a short account of how this has been done.
