Для анализа текущей нагрузки сети среднего и низкого давления оценивается количество сосредоточенных и равномерно распределенных потребителей г. Ангарска и Ангарского городского округа. Анализ состояния сети производится методом теоретического исследования, включающим в себя анализ, абстрагирование и индукцию. Для выбора способов реконструкции и модернизации сети используется абстрагирование от действующего вида газового топлива, используемого в АГО. Основное внимание уделяется перспективному росту потребления в ближайшие 10–20 лет и возможной газификации природным газом Иркутской области вследствие запуска в эксплуатацию магистрального газопровода «Сила Сибири». В результате анализа текущего состояния газотранспортной сети выявлены недостатки, указывающие на необходимость реконструкции и модернизации участков сети и узлов контроля и регулирования. Произведен анализ надежности действующего оборудования с учетом срока его эксплуатации. На основании полученных данных приведены рекомендации по наиболее эффективным способам реконструкции газотранспортных сетей и модернизации узлов регулирования и газоиспользующего оборудования с технической и экономической точки зрения. Таким образом, с учетом роста объёма потребления газового топлива жилищным фондом и промышленным сектором проблема реконструкции газовой сети стоит достаточно остро. Однако необходимо разработать систему газоснабжения с учетом перспективного перехода на природный газ. Этот фактор диктует унификацию проектных решений для любого вида газового топлива.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the research is to analyse the status of the low-pressure gas distribution system functioning in of the Angarsk urban district (AUD), as well as to identify possible directions for its reconstruction and modernization. These measures are aimed at developing the housing stock and the capacity of industrial enterprises. The number of local and distributed consumers in Angarsk and the Angarsk urban district was used to analyse the current load of mediumand low-pressure gas supply systems. To check the status of the gas supply system in the region, a theoretical study was undertaken involving analysis, abstraction, and induction. Choosing the methods for reconstruction and modernization of the system required abstraction from the current gas type used in the AUD. Particular attention was drawn to the forecast of gas consumption in the next 10–20 years and possible gasification of the Irkutsk region due to the launch of the main gas pipeline "Power of Siberia". The conducted analysis of the current status of the gas distribution system revealed shortcomings, indicating the need for reconstruction and modernization of network sections, as well as control and regulation units. In addition, the reliability of the operating equipment was checked, considering its service life. The data obtained were used to develop guidelines for reconstructing the existing gas distribution systems and modernizing control units and gas equipment both technically and economically. An increasing volume of gas consumption by the housing stock and the industrial sector compels us to seriously consider the reconstruction of the gas supply system. However, it is essential to develop a gas supply system that accounts for the possibility of transition to natural gas. This factor calls for the project solutions to be compatible with any type of gas fuel.</p><p> </p></trans-abstract><kwd-group xml:lang="ru"><kwd>газотранспортная сеть</kwd><kwd>падение давления</kwd><kwd>надежность</kwd><kwd>реконструкция</kwd><kwd>модернизация</kwd><kwd>лупинг</kwd><kwd>коэффициент одновременности</kwd><kwd>сосредоточенные потребители</kwd><kwd>внутридомовое газоснабжение</kwd><kwd>бестраншейные способы реконструкции</kwd><kwd>теплота сгорания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gas transmission network</kwd><kwd>pressure drop</kwd><kwd>reliability</kwd><kwd>reconstruction</kwd><kwd>modernization</kwd><kwd>looping</kwd><kwd>simultaneity factor</kwd><kwd>concentrated consumers</kwd><kwd>intra-house gas supply</kwd><kwd>trenchless reconstruction methods</kwd><kwd>heat of combustion</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Винокуров М.А., Суходолов А.П.
