Это стимулирует инженеров все чаще обращать внимание на учет погодных факторов, влияющих на температуру проводников, используя соответствующие математические модели. Тем самым обеспечивается возможность оперативно реагировать на изменения в тепловом режиме проводников.</p><p>В данной статье на основе уравнений теплового баланса произведен вывод аналитических выражений для расчета температуры изолированных и неизолированных проводов воздушных линий электропередачи. Представленная математическая модель подтверждена сравнением с методом конечных элементов, реализованным в программном комплексе Ansys. Исследование также включало в себя комплексное изучение того, как температура окружающей среды, скорость ветра и атмосферное давление влияют на тепловое состояние проводника.</p></abstract><trans-abstract xml:lang="en"><p>Due to the growing demand for electricity and the deterioration of existing infrastructure, overhead power lines in many cases are forced to operate at the limit of their thermal capabilities. This encourages engineers to increasingly pay attention to the consideration of weather factors affecting the temperature of conductors, using appropriate mathematical models. This makes it possible to quickly respond to changes in the thermal regime of the conductors.</p><p>In this article, based on the equations of thermal balance, analytical expressions are derived for calculating the temperature of insulated and non-insulated wires of overhead power lines. The presented mathematical model is confirmed by comparison with the finite element method implemented in the Ansys software package. The study also included a comprehensive study of how ambient temperature, wind speed and atmospheric pressure affect the thermal state of the conductor.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>активное сопротивление</kwd><kwd>потери мощности</kwd><kwd>линия электропередачи</kwd><kwd>метеорологические факторы</kwd><kwd>температурный режим</kwd><kwd>изоляция</kwd><kwd>метод конечных элементов</kwd><kwd>пропускная способность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>active resistance</kwd><kwd>power losses</kwd><kwd>power transmission line</kwd><kwd>meteorological factors</kwd><kwd>temperature regime</kwd><kwd>insulation</kwd><kwd>finite element method</kwd><kwd>throughput capacity</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">World Energy Investment 2024.
