浅谈长输管道典型SCADA系统特点对比

摘要

Expounds the present situation of the long-distance pipeline SCADA system at domestic and abroad,compare two kinds of typical structure of SCADA system is currently widely used,and list their characteristics,advantages and disadvantages.Furthermore, through analyzing the reliability and failure rate of two structures,discussed according to different process requirements select the appropriate structure of SCADA system,proposed dispatch center and station control system,in order to maximize the role of different system structures, improve production efifciency.%阐述了长输管道广泛应用的SCADA系统的现状，对比了两种典型的SCADA系统结构，并列举了各自的特点和优缺点。此外，通过对两种结构可靠性和故障率的分析，论述了可根据不同的工艺需求选择合适的SCADA系统结构，提出了调度中心和站控系统选取的依据，以便充分发挥不同系统结构的作用，提高生产效率。
