摘　　要：针对当前我国火电厂脱硫技术自动化水平不高、脱硫率较低等问题,设计了一套基于PROFIBBUS-DP技术的火电厂脱硫控制系统,具有实时性强,能够实现信息管理(MIS)和实时监控(SIS)等特点。应用于河南豫新发电厂,脱硫效率达到80%以上,实现了减排效果。The thermal power plant desulfurization technology level was old,the desulfurization rate was low.Thus,a set desulfurization control system based on the PROFIBBUS-DP technology was designed.The system has good real-time,can realize the information management(MIS) and real-time monitoring(SIS),and is applied to Yuxing power plant of Henan.It showed that the system can improve the desulfurization efficiency,reduce concentration of SO2 and dust emission effectively,achieve the emission reduction effect.
