摘　　要：京石邯(北京—石家庄—邯郸)输气管道输量大、气源多、用气量波动大,管道内压力、流量、流向等运行参数变化频繁,给清管作业期间清管器运行速度控制造成较大困难。为准确控制清管器运行速度,采用PSIGanesi软件建立了京石邯输气管道在线仿真模型,其清管器追踪功能可以实时计算清管器在管道中的位置、清管器平均速度、剩余清管距离、剩余清管时间等,为清管作业方案的临时调整提供最新的管网运行状态。选取石家庄站—邢台站管段,利用PSIGanesi在线仿真模型的清管器追踪功能实时模拟了皮碗、直板、钢刷3种清管器的清管作业,将现场实际的清管时间与仿真模型实时追踪时间进行对比,分析了造成偏差的原因,并提出了修正方法。研究成果可为管道管理部门准确把握清管过程中清管器位置及运行速度提供参考。The Beijing-Shijiazhuang-Handan Gas Pipeline is characterized by large transportation capacity,multiple gas sources,large fluctuations in gas consumption,and frequent changes in operating parameters such as internal pressure,flow,and flow direction in the pipeline,which cause the major problems in pig operation speed control during pigging operations.In order to accurately control the operating speed of the pig,an online simulation model of Beijing–Shijiazhuang–Handan Gas Pipeline was established with PSIGanesi software.With the pig tracking function of the model,the location of pig in the pipeline,the average speed of the pig,the residual pigging distance and the remained pigging time can be calculated in real time,so as to provide the latest operation status of the pipeline network for the temporary adjustment of scheme for pigging operation.Herein,pigging operation with a cup pig,a straight plate pig and a brush pig in the pipeline section between Shijiazhuang Station and Xingtai Station was simulated in real time with the pig tracking function of PSIGanesi online simulation model.On this basis,the actual pigging time on site and real-time tracking time of the simulation model was compared,thereby the causes resulting in the deviations were analyzed and a correction method was developed.The research results could provide reference for the pipeline management departments to accurately locate the pig and control its operating speed.
