摘要：在管道发生事故工况时，管道安全保护系统是管道输送整体安全受控的主要保障，在保护过程中该系统能够自动触发并执行，不需人工干预，
可大大降低管道事故引发的次生灾害
常用的管道安全保护措施包括水击超前保护、进出站泄压保护、自动压力越站保护、压力超限保护、紧急停车保护等。针对兰郑长成品油管道，通过离线仿真软件计算得出设计输量下全线水力坡降。在中间系站用系情况下，105内采取水击超前保护程序，管道全线不会超压，三门峡分输票站压力越站，实现管道降量输送，管道输量为1223m/h。在末站罐前间门误关断时，郑州站关闭信号发出后，105内采取水击超前保护程序，管道全线需停输才不会超压。目前管道安全保护设计依托SCADA系统，已经越来越智能化，并形成了一套成熟、完整的系统工程，

Liu Chao, Wang Dapeng, Li Yixin, Xu Jianan, Hao Yuanfang, Xian Yulong
Abstract: Pipeline safety protection system is the main guarantee for the entirety safety of the pipe sys tem in the condition of accident. The process triggers and executes automatically, without manual in tervention, which greatly reduces the secondary disasters caused by pipeline accidents. The common methods of safety protection for long distance pipelines includes water hammer advanced protection, Inlet/outlet pressure relief protection, automatically pressure passby station, pressure overrun protec tion and ESD system. And with the specific example of the LanZhengChang product oil pipeline, the off line simulation software has calculated the whole pipe hydrdulic gradient in design condition. Supposing the booster pump station malfunctions shut down when the flow rate is 1 223 m'/h, ther the surge pre=protection program
can executive within 1O seconds, the pressure limit of the pipe will
not be broken and Sanmenxi distribution& pump
statior
n automatically pressure passby to reduce
the flux.When the valve of terminal station before tanks closes in misoperation then the signal of
the surge
Zhengzhou station closure be sent,
pr
program can execute within 10 seconds,
eventually the whole pipeline has to be shutdown and there will not be overpressure.
Based on SCA
DA system, the pipeline safety system is more and more intelligent and evolve to be a suit of mature and prefect system projects.

随《石油天然气管道保护法》的正式实施以及社会环境意识、公共安全意识的不断提高，油气管道安全间题越来越多地受到重视。管道安全保护系统不仪能够处置管道运行申因超安全极限引发的风险，而且能够监测和处理自身的故障，按照系统预定程序，自动执行一系列的指令（无需人工干预），从而确保工作人员、工艺设备和周边环境的
安全。目前的管道安全保护设计依托SCADA系统，已经形成了一套成熟、完整、系统的解决方案。
