Abstract

The simulation of the gas supply network in the environment of the graphical interface Matlab - Simulink is carried out in the work, which takes into account the change of parameters of this network at change of qualitative characteristics of energy resource, namely - calorific value of natural gas. The created model showed reduced volumes of natural gas consumption by network consumers in case of improvement of energy quality. The transition of payments for natural gas from volumetric to energy units is normatively supported by international and state legislative documents, the comprehensive coverage of which is given in the paper. This transition of calculations should be accompanied by the development of a system of tools for determining the specific heat of combustion of energy in the flow mode. In the paper it is offered to use this metrological system of means of an estimation of qualitative indicators of an energy resource for the purposes of an additional diagnostic sign of a technical condition of the gas pipeline. Tracking the ranges of changes in the calorific value of natural gas can serve as a basis for assessing changes in the technical condition of the pipeline itself. A diagram of this connection between the technical condition of the pipeline and the quality of the gas flowing through it is given in this paper. Also, to confirm the correlation between the quality of natural gas and the technical condition of the pipeline, the paper presents the results of an experimental study of the possibility of determining the defects of the pipeline by measuring changes in energy quality. The results of this study show that a gas pipeline with corrosion damage is characterized by a significant change in the calorific value of natural gas flowing through it (for the study area "Tustan - Diliyevo" it was 10%).
