 摘要：火电厂辅助车间设备的控制功能通常采用可编程序控制器 PLC 来实现，但近年来，越来越多的电厂开始采用DCS完成辅助车间设备的控制操作。本文对采用DCS和PLC实现电厂辅助车间设备的控制进行了比较，认为DCS 系统用于全厂辅助车间设备控制具有系统可靠性更高、功能更强大、开放性更好、更加便于实现全厂管控一体化、系统性能价格比更好等优点。北京国电智深控制技术有限公司近年来承接了若干个电厂的全厂辅助车间DCS控制工程，均获得了较好效果，本文列举了其中典型工程应用方案。 关键词：PLC；DCS；火电厂；辅助车间；控制 Abstract: Thermal Power Plant BOP control usually uses PLC to achieve, but in recent years, more and more power plants began to use the DCS to complete the control operation. In this paper, the two methods of DCS and PLC to the control of power plant BOP equipment are compared, as a result，that DCS for the BOP control system is considered more reliable, more powerful, more open, more easy to achieve the whole plant Control integration and Cost-effective. In recent years，a number of BOP control system of thermal Power Plants undertaking by Beijing Guodian Zhishen control Technology Co., Ltd., were obtained good effect. This paper cited one typical project. Key words: PLC, DCS, Thermal Power Plant, BOP, Contorl
