Gas Transmission Pipeline Network Simulation Technology And Operation Condition Analysis

With the rapid growth of the national economy,the progressive growing demand forhigh-quality clean energy and fuel,such as natural gas,is needed for my nation.My nation’s gaspipeline system is becoming large, pipeline network transmission system gradually becomesmore complicated. To understand and grasp the pipe systems operating rules,to analyze anddeal with the accident-operation of the pipeline system,to demonstrate and put forward theeconomical running program is becoming difficult for the pipeline manager.As the same time,pipeline system’operational state has a direct impact on the natualgas’production,supply,maketing.So pipeline manager find out mutual influence flowingrelation among each parameter in the pipe network to the result of the reasonable schedulingand optimal operation.In response to these circumstances,the simulation theory,SPS software and the pipelineinformation and operating data of the Central Asia natural gas pipeline as a case study arecombine to build the Central Asia natural gas pipeline simulation model,and thus for a varietyof operating conditions of the simulation analysis.Fist,the model of steady-state and dynamicerror is analyzed and the dynamic stability analysis of initial conditions for dynamicsimulation results is discussed.Then the pipeline system’running programs in a variety ofconditions and the impact of guound temperature,wall roughness, outbound temperaturechange for the gas system are analyzed on the certain degree. The rusult for Central Asianatural gas pipeline operation scheduling and output growth transformation of late has certainreference value, ensure that gas pipeline economical, efficient operation.Finally, on the basis of central Asia gas pipeline hydraulic model, the failure ofcompressor stations,pipeline burst pipes,pipe blockage,gas supply interruption accidentconditions typical model are established to analyze the above accident conditions on thepipelie system effects. such as the image of a chart describes a gas pipeline change variousparameters, the pipeline for a self study time and venting time, while based on the assumption,the pipe for the gas peak of the last paragraph, the operation of the pipeline to run on there issome guidance to further improve the planning and design, in order to improve pipeline safety,economic operation.
