英文摘要 Subject:Dynamic Simulation Analysis ofNatural Gas work inMethod of Characteristics Speciality:Oil-Gas Storage and Transportation Engineering Name: Song Tao(signature) Instructor:Wang Shouxi(signature) Abstract The advantages ofnatural pared tocoaland oil,have no waste water,110 residue, safer,higher calorificvalue ,natural gas ed inthe era ofthe LCE(10w·carbon economy).Pipeline as the main mode oftransportation ofnatural gas, forwards long—distance,large-diameter,high pressure,and cyberization,and gradually es alarge-scale plex gassupply naturalgas system es more and more huge plex,it increases thedifficulty ofunderstanding andmastering the operation rules accurately,limiting demonstrate and present areasonable optimal operation scheme,and letting theanalysis and process capacity ofitsemergency operating conditions es ,it seriously impediment to thenatural gas work system inrational planning anddesigning,safely dispatching management and accurate operating ,in order tostudy plexity oflarge natural gas pipeline system accurately,gas work simulation technology thesupporting skillwhich helps tomake decisions ofthenatural work,it revealsthe flowprocess,heat and water distribution under thedifferentdesigning,managing and operating from this,it also describes thechanging trend and process ofwater and heatunder different manipulations,changes and accident ,this paper has a great significance fortheoptimal design,effective management,reasonable dispatch and reliable operation. This paper investigates alarge number ofdomestic andforeign in steps withtheresearch ofdynamic simulation inthenaturalgas work andanalyses thedynamics simulation work. Atfirst,otherpapersignore questions such asconvection item,inertia itemand neutral item inthe process of present natural gas pipeline dynamic ,this paper constructs thenatural gaspipeli
