Abstract: The model design and software development of products pipeline simulation is introduced based on the example of Lanzhou—Chengdu—Chongqing Products Pipeline.There are equipment, offtake station, initial station and so on in the simulation model.The simulation software consists of 11 models.The frame of simulation software also is given in the paper.The simulation system will help operators to master promptly the change of the surge process during the dynamic running of pipeline and monitor the whole pipeline.
