摘要
在原SCADA系统半自动控制方式的基础上,提出对控制功能进行提升。通过对控制逻辑的优化改造,实现根据需要可以自动完成站场工艺操作和设备联锁动作,从而代替值班人员对设备运行的监视控制,进一步提升了天然气管道自动化控制水平,同时提高了自动化系统运行的可靠性和安全性。
Basing on original SCADA system’s semi-automatic control mode,the enhancement of the control function was proposed.Through optimizing the control logic,the process operation and the interlocking action of the station field can be completed automatically as required and supervisory control over the equipment by the operator on duty can be replaced to further promote the auto-control level of natural gas pipelines and to effectively improve both reliability and security the automatic system.
