Рассмотреть наиболее актуальные и важные проблемы параллельной работы генераторных агрегатов в составе автономных электротехнических комплексов современных морских судов, таких как переход дизель-генераторных агрегатов в режим обратной мощности и существование обменных колебаний мощности при параллельной работе. Рассмотреть возможность совершенствования метода устранения обменных колебаний мощности с использованием карт зависимостей амплитуды колебаний от параметров дизель-генераторных агрегатов. МЕТОДЫ. При решении поставленной задачи применялась математическая модель автономного электротехнического комплекса, позволяющая учесть зазоры люфтов в контурах регулирования частоты вращения параллельно работающих дизель-генераторных агрегатов. РЕЗУЛЬТАТЫ. Построена карта зависимости угла нагрузки от зазоров люфта. Доказана полная идентичность карт зависимости угла нагрузки от зазоров люфта и карт зависимости амплитуды обменных колебаний мощности от зазоров люфта. В критерии определения значения амплитуды обменных колебаний мощности предложено использовать угол нагрузки генераторов вместо огибающих токов генераторов. ЗАКЛЮЧЕНИЕ. Использование угла нагрузки параллельно работающих генераторов позволяет повысить быстродействие и точность блока устранения обменных колебаний мощности. Разработанный подход позволяет контролировать переход генераторных агрегатов в режим обратной мощности и появление обменных колебаний мощности на основе измерения углов нагрузки генераторов.</p></abstract><trans-abstract xml:lang="en"><p>THE PURPOSE. Consider the most pressing and important problems of parallel operation of generator sets as part of autonomous electrical complexes of modern sea vessels, such as the transition of diesel generator sets to reverse power mode and the existence of power exchange oscillations during parallel operation. Consider the possibility of improving the method for eliminating power exchange oscillations using maps of dependences of the amplitude of oscillations on the parameters of diesel generator sets. METHODS. When solving the problem, a mathematical model of an autonomous electrical complex was used, which allows to take into account the backlash clearances in the control loops of the rotation frequency of parallel diesel generator sets. RESULTS. A map of the dependence of the load angle on the backlash clearances was constructed. The complete identity of the maps of the dependence of the load angle on the backlash clearances and the maps of the dependence of the amplitude of the power exchange oscillations on the backlash gaps has been proved. In the criterion for determining the value of the amplitude of the power exchange oscillations, it is proposed to use the load angle of the generators instead of the envelope currents of the generators. CONCLUSION. The use of the load angle of parallel operating generators allows to increase the speed and accuracy of the unit for eliminating power exchange oscillations. The developed approach makes it possible to control the transition of generating sets to the reverse power mode and the appearance of power exchange oscillations based on measuring the load angles of the generators.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>обменные колебания мощности</kwd><kwd>параллельная работа</kwd><kwd>автономный электротехнический комплекс</kwd><kwd>угол нагрузки</kwd><kwd>генераторный агрегат</kwd><kwd>экспериментальные исследования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>power exchange oscillations</kwd><kwd>parallel operation</kwd><kwd>autonomous electric power complex</kwd><kwd>load angle</kwd><kwd>generating set</kwd><kwd>experimental research</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">Грачева Е.И., Ильясов И.И., Алимова А.Н.
