摘　　要：大庆石化公司丁二烯抽提二套装置螺杆压缩机原来应用PLC控制系统。由于控制和操作部分结构设置不合理,系统故障率较高。2012年该系统升级改造成S7-400系列PLC控制后,新型PLC在螺杆压缩机控制系统已经连续稳定运行了18个月,实现了机组控制的优化与稳定。The screw compressor of the Second Butadiene Extraction Unit of Daqing Petrochemical Company used PLC controlsystem in the first place. The failure rate was high due to part of the structure setup of control and operation was unreasonable. Afterupdating and rebuilding of this system to S7-400 series PLC in 2012,the new PLC has been continuously and stably running in thescrew compressor control system for 18 months,and realized the optimization and stability of the compressor control.
