| Title of the article | Numerical testing of mathematical models for monitoring the safe functioning of gas supply systems |
| Abstract. | The developed algorithms and software systems implemented previously developed method for solving the problem and the mathematical model for estimating the static gas supply systems. The same software package implements a mathematical model developed earlier for the formation pseudo measurement to overcome the lack of experimental data about the object of research. At the basis of mathematical models applied the principle of energy equivalenting. The software package provided with operational control of the rapidly changing mode settings, based on the realization of two interrelated problems algorithmically: diagnosis of leaks and static evaluation. Performance of software provided through the adoption of the aggregate of the estimated parameters in the form of selection among consumers, which is not the traditional approach. The practical value of the proposed method is that the pressure of the selected nodes as the estimated parameters, allowing for information about the initial state of the object to apply the most appropriate way to control the mode of operation of a manometer shooting. The developed software package enabled a computer experiment, confirmed the efficiency of the earlier models with an accuracy corresponding to the quality of the original experimental data obtained in a survey of pressure sensors installed on the gas supply system. The developed software is possible to use for technical diagnosis of urban gas supply systems. Introduction of the complex into practice will ensure reliable operation and cost in the design and operation of the protection, and hence improve their safety in use. |
