Развитие электрических сетей напрямую зависит от стоимости и надежности конструкций воздушных линий электропередачи (ВЛ), для чего необходимо, прежде всего, уточнение статических и динамических нагрузок и воздействий с целью оценки несущей способности при проектировании и эксплуатации; поиск, разработка и апробация новых оптимальных решений опор ВЛ, а также комплексный подход к проектированию сети как единой конструкционной системы на основе учета требований изготовления, монтажа и эксплуатации. Цель исследования — поиск оптимальной конструктивной формы стальных узкобазых башенных и портальных опор ВЛ напряжением 35 и 110 кВ.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. При исследовании башенных одностоечных и портальных опор ВЛ 35 и 110 кВ с диагоналями и распорками по массе учитывались нормальные, аварийные и монтажные режимы работы для анкерованных участков с углами поворота воздушной линии от 0 до 60°. Линия рассматривалась как единая система. При изучении анкерно-угловых опор по массе учитывались возможные режимы работы: нормальные, аварийные и монтажные для различных углов поворота трассы линии.</p></sec><sec><title>Результаты</title><p>Результаты. Разработан алгоритм определения напряжений для всех регламентируемых нормативными документами режимов работы токоведущих проводов и необходимого количества пролетов ВЛ. Впервые решена задача расчета напряженно-деформированного состояния ВЛ как единой системы с учетом совместной работы токоведущих проводов, грозотросов, гирлянд изоляторов, опор и фундаментов. На основе предложенного численного метода оптимизации дополнительно снижены показатели массы и стоимости узкобазых опор до 20 %.</p></sec><sec><title>Выводы</title><p>Выводы. Предложенные узкобазые опоры технологичны в изготовлении, монтаже и эксплуатации. Портальные опоры с подкрепляющими диагоналями и без них рациональны в анкерно-угловых вариантах 110 кВ, особенно при больших нагрузках из плоскости и значительных перепадах рельефа местности, а также в промежуточных вариантах 110 кВ при высоте опор до 27 м. На ВЛ напряжением 35 кВ применение портальных свободностоящих опор дает положительный эффект только для промежуточных вариантов высотой до 20 м.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The development of electric networks directly depends on cost and reliability of overhead line structures, which requires, first of all, clarification of static and dynamic loads and impacts in order to assess the bearing capacity during design and operation; search, development and testing of new optimal solutions for overhead line supports, as well as well as an integrated approach to network design as single structural system based on requirements for manufacturing, installation and operation. The purpose of work is to find the optimal structural form of steel narrow-base tower and portal supports for 35 and 110 kV overhead lines.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. When studying tower single and portal supports of 35 and 110 kV overhead power lines with diagonals and spacers by weight, normal, emergency and installation modes of operation were taken into account for anchored sections with overhead line rotation angles from 0 to 60°. The line was considered as single system. When studying anchor-angle supports by weight, possible operating modes were taken into account: normal, emergency and installation for different rotation angles of line route.</p></sec><sec><title>Results</title><p>Results. Has been developed an algorithm for determining voltages for all operating modes of current-carrying wires and required number of overhead power line spans regulated by regulatory documents. For the first time has been solved the problem of calculating the stress-strain state for overhead power line as single system, taking into account the joint operation of current-carrying wires, ground wires, insulator strings, supports and foundations. Based on proposed numerical optimization method mass and cost of narrow-base supports have been further reduced by up to 20 %.</p></sec><sec><title>Conclusions</title><p>Conclusions. Proposed narrow-base supports are technologically advanced in manufacturing, installation and operation. Portal supports with and without reinforcing diagonals are rational in anchor-angle versions of 110 kV, especially with large loads from plane and significant differences in terrain, as well as in intermediate versions of 110 kV with support height of up to 27 m. On 35 kV overhead lines the use of portal free-standing supports gives a positive effect only for intermediate versions up to 20 m high.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>воздушная линия электропередачи</kwd><kwd>узкобазая опора</kwd><kwd>напряженно-деформированное состояние</kwd><kwd>расчетная модель</kwd><kwd>автоматизированный расчет</kwd></kwd-group><kwd-group xml:lang="en"><kwd>overhead power line</kwd><kwd>narrow-base support</kwd><kwd>stress-strain state</kwd><kwd>design model</kwd><kwd>automated analysis</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">Крюков К.П., Новгородцев Б.П.
