基于DCS的空预器吹灰顺序控制系统改造

Reformation of the Air Pre-heater Blowing Order Control System Based on DCS

本文针对大唐湘潭发电有限责任公司吹灰顺序控制系统全部由PLC控制的现状,提出了一种基于DCS的控制方式。综合分析空预器吹灰控制系统的控制要求,详细介绍了DCS实现空预器吹灰系统的过程。运用于实际的结果证明,此次改造提升了空预器吹灰顺序控制系统的安全性、稳定性、可操作性等。

The current blowing order control system of Datang Xiangtan Power Generation Company is controlled by PLC. This paper proposes a control method based on DCS. This paper comprehensively analyzed the control requirements of air pre-heater blowing control system, and introduced the realization process of air pre-heater blowing system by DCS. The application results show that the reformation has improved the security, stability and maneuverability of air pre-heater blowing order control system.
