Abstract

High pressure simulation of gas pipeline networks is one of the factors which enables to aid the system dispatcher decisions. Because of its complexity, this problem can be solved effectively only by using a computer techniques. As a basic fact one should recognize the dynamic phenomena appearing in the network, accumulating of the gas and a great number of admissible decisions. Moreover in order to elaborate proper control decisions it is necessary to perform a large number of simulations. Each of this simulation is connected with the necessity of the iterative solutions of nonlinear differential equation systems describing the dynamic phenomena appearing in the network. In the papers [4], [5] the solution methods of the above mentioned problem in the case of quasi static flows are described. This algorithms ensure a satisfactory concordance between the results obtained from simulation with the measuring data carried out on a real network especially in case of low pressure gas networks. Only in such situation it is possible to neglect in the model of network the phenomena of gas accumulation.
