摘　　要：长输管道站点分布广、数量多,操作控制方式以站控和中控相结合且以中控统一集中调度为主。通过对长输管道SCADA系统国内外情况及发展的分析,比较了目前在长输管道应用中的SCADA系统调度中心两种典型系统结构;通过对两种结构的优缺点和故障率的比较和分析,论述了不同条件下相应的系统结构在长输管道中的应用场合和选择方式;提出了远控站、分控站和主控站设立的依据和方法,最大限度地发挥不同结构的作用。Long transportatxon plpehne has large amount oI WlClely dlstrlbutecl stations. Ntatlon control and centralized control are combined, and unified and centralized scheduling through central is mainly adopted. By analyzing the status and development of SCADA system of long transportation pipeline at home and abroad, the structure of two typical systems used in SCADA system scheduling centre for long transportation pipeline are compared. By comparing and analyzing the advantages and disadvantages and failure rate of these two structures, the application sites and selection modes of related system structure under different conditions in long transportation pipeline are discussed. The setting bases and method of remote control station, separate control station and central control station are put forward to maximize the roles of different structures.
