SIMULATION OF GAS TRANSMISSION SYSTEM

摘要

Gas supply system is a control system consists of gas regulator and pipeline. Until now, as a model of gas pipeline, lumped parameter model has been used. However in real system, there is an interaction between gas pipeline and gas regulator, response of system is different from simulation with lumped parameter model. Therefore, in accurate pressure control, model of gas pipeline is needed. There are many reports about the transfer function model of the fluid pipeline. But suitable model about the gas transmission pipeline has not known. From these point of view, we proposed new transfer function model considering the heat transfer between pipe wall and gas and temperature change, and described the effectiveness of this model by comparison with experiment in previous paper. In this paper, we conform the assumptions of that new model using experiments and the numerical simulation of gas transmission pipelines.
