With the continuous expansion of the scale of the gas pipeline network and the increasing of the equipment in the gas pipeline, the energy consumption of the pipeline increases sharply, threatening the steady-state operation of the gas pipeline.The steady flow equation of gas pipeline is constructed, the gas flow in the pipeline is calculated, and its motion characteristics are analyzed.Based on the results of feature analysis, the objective function of technology optimization is set.NSGA-Ⅱ algorithm is used to solve the multi-objective optimization function of technical optimization, so as to obtain the technical optimization parameters and complete the optimization process.Through the simulation experiment, the results show that the stability of the pipeline is 85.14%~86.71%, the fluctuation of energy consumption is 5.08%~5.79%, and the internal pressure of the gas pipeline is reduced.The application effect of the optimized technology is obviously better than other technologies, which can effectively control the energy consumption of pipeline, ensure the stability of pipeline operation, and improve the safety of pipeline transmission.
