Обеспечение сохранения устойчивости асинхронных двигателей при провалах напряжения является важной задачей обеспечения непрерывности технологического процесса, а также снижения материальных убытков. ЦЕЛЬ. Привести основные причины провалов напряжения. Разработать имитационную модель, соответствующую типовой схеме электроснабжения нефтеперекачивающей насосной станции с группой асинхронных двигателей в качестве нагрузки. Выполнить две серии расчетов по определению параметров электрического режима при провалах напряжения и последующем восстановлении напряжения на шинах питающей подстанции. МЕТОДЫ. При решении поставленной задачи применялся программный комплекс PSCAD. РЕЗУЛЬТАТЫ. В статье описана актуальность темы, приведены основные причины провалов напряжения. Выполнено моделирование провалов напряжения, возникающих в результате короткого замыкания на оборудовании подстанции. Выполнены серии расчетов, отличающиеся друг от друга измененными исходными данными: место возникновения короткого замыкания (далее – КЗ), выдержка времени автоматического ввода резерва (далее – АВР). Выполнен анализ полученных результатов. ЗАКЛЮЧЕНИЕ. По результатам проведения испытаний видно, что снижение напряжения на шинах низшего напряжения подстанций после работы АВР тем ниже, чем больше выдержка времени АВР. В настоящей работе максимальная выдержка времени составляла 7 секунд, при этом, нарушения устойчивости асинхронных двигателей не возникло. Также определена необходимость исследования работы группы асинхронных двигателей при авариях во внешней электрич еской сети.</p></abstract><trans-abstract xml:lang="en"><p>Voltage dips are quite frequent and dangerous phenomenon, which can lead to disruption of the production process. Ensuring the stability of induction motors during voltage dips is an important task to ensure the continuity of the technological process, as well as to reduce material losses. THE PURPOSE. List the main causes of voltage dips. Develop a simulation model corresponding to a typical power supply scheme for an oil pumping station with a group of asynchronous motors as a load. Perform two series of calculations to determine the parameters of the electrical mode in case of voltage dips and the subsequent restoration of the voltage on the buses of the supply substation. METHODS. When solving the problem, the PSCAD software package was used. RESULTS. The article describes the relevance of the topic, the main causes of voltage dips are given. The simulation of voltage dips resulting from a short circuit on the substation equipment has been performed. A series of calculations were performed, differing from each other in the changed initial data: the place of occurrence of a short circuit, the time delay of automatic transfer of the reserve. The analysis of the obtained results is carried out. CONCLUSION. According to the test results, it can be seen that the decrease in voltage on the low voltage buses of substations after the operation of automatic transfer switch is the lower, the longer the time delay of automatic transfer switch. In this work, the maximum time delay was 7 seconds, while there was no violation of the stability of the induction motors. The need to study the operation of a group of asynchronous motors in case of accidents in an external electrical network is also determined.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>асинхронный</kwd><kwd>двигатель</kwd><kwd>провал</kwd><kwd>напряжения</kwd><kwd>пуск</kwd><kwd>самозапуск</kwd></kwd-group><kwd-group xml:lang="en"><kwd>asynchronous</kwd><kwd>motor</kwd><kwd>failure</kwd><kwd>voltage</kwd><kwd>start</kwd><kwd>self-launch</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">Исмагилов Ф.Р., Максудов Д.В., Гареев А.Ш. и др.
