Research on simulation of the ring-like pipeline system of natural gas

Due to the complex structure and installation of the ring-like pipeline system of natural gas, it is difficult to monitor the actual situation by equipments. Having taken into consideration of the restrictions of the node pressure and pipe flow, the author simulates the pipeline system by existing basic data aiming at optimizing the pipeline system. In relation with the current situations, we simulate the actual situation of the existing pipeline system in this mode means, which demonstrates that the means can play a guiding role in pipeline system operation in local cities. Besides, the means supplies scientific tools and foundations for the new, renew and enlarge project.
