%X A pipeline operation optimization model with minimum energy consumption as the objective function was established based on the dynamic programming method. The model was applied to a 3840£¿km gas pipeline whose designed pipeline capacity was 170£¿¡Á£¿108£¿t/a. There were 40 stations in the line, including 22 compressor stations and 32 compressors. The solution time was controlled within 60£¿s to show that the algorithm was fast and effective. The number of starting-up compressors in the optimized scheme is two more than that in the actual operation scheme, and the total pressure drop of the pipeline decreased by 3.40£¿MPa, the average efficiency of the gas turbine units increased by 4.234%, the average efficiency of the electric drive units increased by 4.875%, and the power decreased by 18,720.38£¿kW, confirming the validity and feasibility of the optimization model
