Аннотация. Актуальность исследований обусловлена снижением потерь электроэнергии в системах передачи электрической энергии класса напряжения 6-35 кВ, представленных преимущественно витыми неизолированными проводами и одновременным повышением требований к техническим и физикомеханическим характеристикам используемых проводников. В данной работе выполнен анализ влияния внешних воздействий на линию электропередачи, проанализированы потери электроэнергии, обусловленные нагревом проводника, а также возникновением коронного разряда в зависимости от формы поперечного сечения витого неизолированного провода. По результатам выполненного анализа получена целевая функция определения энергоэффективной формы провода воздушной линии электропередачи класса напряжения 6-35 кВ по различным критериям. Ключевые слова: неизолированный провод линии электропередачи, энергоэффективная форма.

The paper demonstrates an approach to the creation of the mathematical model of electric power transmission grid with using an artificial neural network for training a centralized system of ACS RPVC. The efficiency of its application was proved during the full-scale experiment on the laboratory bench.

The problems of increasing the energy efficiency of oil and gas production are becoming very urgent. The cost of purchasing electricity greatly affects the cost of hydrocarbons. The cost of electricity is an important contributor to the price of oil and gas. This is due to low oil and gas prices and expensive electricity. Reliable power supply to oil and gas fields is a big problem. Oil companies are starting to use gas turbine power plants, solar panels and wind turbines. Under these conditions, oil companies are trying to optimize their energy costs. Most of the electricity is consumed by downhole production and injection wells. Development of mathematical models allows minimizing power consumption. All technological processes of oil and gas production are interconnected. Water injection into the reservoir affects the production pumps. The operation of borehole pumps affects the oil treatment and pipeline transportation systems. The tools’ synthesis for modelling development strategies in the electric power field into oil and gas producing enterprises (OGPE) is considered. The structural and parametric identification of the macromodel for energy consumption in the OGPE energy complex into the generalized Golden section metric is performed. The calculations’ results are given.

Some mathematical models of the scheduled normalized dynamic characteristics of the process of oil and gas wells drilling were developed. These models practical application for assessment of the technological process power efficiency was examined. The identified models soft testing was performed.
