Hydraulic Characterization of Multi-Source Natural Gas Pipeline Network Based on Computer Optimization Algorithm

When performing hydraulic characterization, the interaction between gas sources can lead to some deviation of the calculated results from the measured values. In this paper, for the actual pipeline network data, the hydraulic characteristics of multi-source natural gas pipeline network are analyzed by computer simulation, and the natural gas moiré inversion model is established by genetic algorithm, and the multi-source natural gas pipeline network is simulated and optimized. According to the nodal algorithm calculation, the pressure drop change rule of pipe section under different gas conditions is determined, which provides a theoretical basis for the calculation of gas parameters of each pipe section, thus improving the accuracy and reliability of hydraulic characteristic analysis.
