DIRECTIONS OF TRANSFORMATION OF ENERGY SUPPLY SYSTEMS TAKING INTO ACCOUNT THE PROSPECTIVE DEVELOPMENT OF TERRITORIES

Abstract

Modern cities have a multi-level structure of technological systems that functionally and organizationally meet the needs of consumers. The development of urban areas requires an integrated approach. Heat and gas supply systems are the main element of energy systems. In accordance with the economic, social and technological conditions, heat and gas supply systems undergo organizational and structural transformations. The purpose of the study is to develop promising schemes of heat and gas supply systems for territories based on mutual influence. Methods. Based on the analysis of the functional and planning zoning of urban areas, the calculation method provides options for the development of heat and gas supply schemes. The implementation of modern standards of heat supply is possible due to multivariate approaches. The reliability of the research results is ensured by the use of proven calculation methods. Residential neighborhoods with a load on heat supply and household consumption are considered as the main consumers. Small industrial and municipal facilities are taken into account when planning the use of energy resources in the considered territory. Industrial consumption, as a rule, has an independent system of heat and gas supply. The method for determining loads is based on specific normative indicators. When developing the gas distribution scheme for urban areas, the possibility of spreading the load on the heat supply is taken into account. Results. On the one hand, the developed variants of heat and gas supply schemes were considered as alternative ones. Both the scheme of the main heat supply networks and the gas distribution scheme will be able to perform functional tasks to provide subscribers with resources for the considered design area independently. On the other hand, at different stages of system development, alternative options can complement each other, according to the periods of phased development, taking into account the criteria of reliability and cost-effectiveness. Conclusions. The variants of heat and gas supply systems allowed us to identify the main linear parameters for different building densities. The general material criterion for heat and gas supply systems is the material characteristic. The development of heat and gas supply schemes, taking into account the mutual influence, ensures a stable and economical development of the territory.
