Design Of Electric Drive Control System Of Paper Machines Based On PLC

Paper industry is a complex process industry, currently the world’s paperindustry is toward large-scale, continuous and comprehensive direction. Paper has acomplex production process control, from the early simple control instrumentsbased on conventional regulation, to adopt advanced PLC control, integratedautomation and then rapidly developing (CIPS) controls the level of automation andpaper industry continues to rapidly increase. The continuous paper machine is amechanical pulp paper, the portion of the web section, press section, dryer section,the calender unit, rolls and other components. In recent years, with the developmentof security paper technology for electric drive control system of the paper machinemade increasing demands. AC drive control system for its excellent performanceand less maintenance, etc., in the electric drive machine control system applicationsis increasing.According to the production equipment renovation project, the paper printingfactory in Baoding securities1880mm machine DC drive control system has beenmodified. AC drive designed machine PLC-based control scheme, developed amachine AC drive control system. Machine with inverter control, design speed andload distribution chain control, establishment of industrial Ethernet communicationsystem for the programming of the PLC program design man-machine interfacedesign and control systems. Experimental results show that the commissioning, PLCbased AC drive control system is stable, high precision, ease of maintenance, ease ofoperation and monitoring, security paper production process to meet therequirements of the machine to achieve the transformation of the target. The newhigh-end machine to improve the corporate security paper production capacity tomeet the growing market demand for the security paper.
