Using Simulink package for transient support-parametric simulation in gas pipeline section

The possibilities of the modern software package of block-modular simulation to the transient simulation tasks in the gas stream in the natural gas transportation area are considered. An approach to modeling in vector format the spatially distributed cell model object generated on the special nonlinear basis is offered. This permits to solve the problems on diagnosis and flow control in the transient processes by macro-cellular modeling of its mass and kinetic energy balance. The adequacy of the starting and ending state of the cell model is provided by the calculation of the reference-parameter vector that characterizes the steady-state flow, and by comparing it with these states.
