Abstract
Daily statistics on the volume of gas consumption and the average daily outdoor air temperature for a six-year period were adopted as an information basis for scientific research with the matter of studying the functioning and developing of the regional gas supply system. For the regional gas supply system, the type of structural fields “daily gas consumption – average daily outdoor air temperature” was determined and their constancy over time was proved. For structural fields, 4 temperature ranges are allocated and a system of characterizing indicators was proposed. The regularities of the formation of daily gas consumption from the average daily outdoor air temperature for the proposed temperature ranges were established, the sensitivity coefficient of the relative change in the daily gas consumption with a relative daily change in the outdoor air temperature was determined. Daily models of the gas consumption dependence on the outdoor air temperature was developed, smoothed by a moving average over 30 days for two temperature regions: 1 - the area of the connected state of the heating system, 2 - the area of the disconnected state of the heating system. The seasonal coefficient of gas consumption was assessed.
Highlights
Today, the modern regional gas supply system (RSGS)is a large and, multi-layered, dynamic technological system [1], the major task of which is to ensure safe and uninterrupted supply of natural and liquefied gas to consumers
Statistics on the volume of gas consumption and the average daily outdoor air temperature for a six-year period were adopted as an information basis for scientific research with the matter of studying the functioning and developing of the regional gas supply system
The high degree of similarity of the structural fields in different years was validated by the high coefficient of pair correlation between the series of daily gas consumption in different years
Summary
Is a large (in terms of the number of elements included in it, as well as the number and structure of consumers) and, multi-layered, dynamic technological system [1], the major task of which is to ensure safe and uninterrupted supply of natural and liquefied gas to consumers. Of the entire complex of tasks for the functioning and development of the regional gas supply system, the most acute today are[2-8]: 1. Drawing up applications for the planned volume of gas supplies. 2. Elaboration of projects for the development and reconstruction of gas supply and gas storage systems. 3. Formation of gas tariffs for various groups of consumers, taking into account the profitability of their production. The task of forming applications for the planned volume of gas supplies is currently a priority [3-. 5, 7], which is explained by the requirement of Russian gas suppliers to pay at the adjusted tariffs for deviations from the declared volumes of gas consumption. In connection with the designated tasks, it is urgent to study the regularities of the functioning and development of both individual balance groups and the RSGS as a whole
