Abstract: Based on the actual data of a natural gas pipeline network, an improved minimum cost flow programming model is proposed. The model limits production to market ability, and calculates the optimal transmission scheme. It is found that the approximate simulation and the “analogy optimization” are two commonly used compressible flow optimization methods. The calculation results verify the effectiveness of using the programming model to solve compressible flow problems, which is different from the commonly used methods.

Key words: compressible flow, natural gas pipeline network, optimized transportation
