In response to the problems of a single index and insufficient comprehensive analysis of each transportation step in the energy consumption evaluation system of the natural gas pipeline system,a comprehensive evaluation of the multi-objective decision analysis of the natural gas pipeline system is carried out.Based on the actual production and energy consumption characteristics of the system,evaluation indicators such as self-consumption and gas consumption per unit are proposed.Then,based on game theory,the combination weights of indicators are determined.Finally,a TOPSIS-RSR comprehensive evaluation model is established and the overall energy consumption level of the NP line natural gas pipeline system is evaluated.The results show that in the natural gas pipeline transportation system with a capacity range of 18 billion to 25 billion m3/a,80%of the startup schemes have basically met the overall energy consumption level,while only 10%of the startup schemes have relatively excellent overall energy consumption levels.Under each output step,the software optimization and compressor core replacement renovation have significant effects on reducing energy consumption in the startup plan,with the core replacement renovation having a more significant effect.
