摘要: 介绍了油气长输管道SCADA系统的特点。通过建立SCADA冗余系统的可靠性数学模型, 从理论上对冗余设计方案进行了分析。介绍了SCADA二模式并-串-并冗余系统在陕银输气管道中的应用。Abstract: The features and functions of SCADA system used in pipeline are introduced. A theoretical analysis on redundant design program has been made by means of establishing a reliability mathematical model of SCADA redundant system. In this paper, the application of SCADA system with 2-mode parallel-serial-parallel redundancy in Shaanxi-Yinchuan gas transmission pipeline is introduced.
