Использовались методы теории автоматического управления. Исследования проводились в среде MatLab с применением пакетов имитационного моделирования Simulink и SimPowerSystems. Предложен метод формирования и настройки групповых прогностических регуляторов на основе определения резонансной частоты колебаний ротора ведущего генератора. Указанный подход позволяет получить лучшие показатели качества управления напряжением и частотой в системе электроснабжения при сохранении прежних настроек регуляторов установок распределенной генерации. Установлено, что при подключении дополнительной нагрузки в изолированной системе электроснабжения в 1,75 раза снижается максимальный провал напряжения по сравнению с локальным прогностическим регулированием, а по сравнению с обычными регуляторами – в 3,5 раза. Для указанного режима использование прогностических регуляторов в 3 раза уменьшает время переходного процесса скорости вращения ротора синхронного генератора. В режиме пуска мощного электродвигателя (благодаря прогностическим регуляторам синхронных генераторов в системе электроснабжения) в 1,5 раза уменьшается провал напряжения, а после пуска в 1,4 раза снижается перенапряжение. При кратковременном трехфазном коротком замыкании по сравнению с локальным регулированием групповые прогностические регуляторы позволяют в 1,5 раза уменьшить время переходного процесса и в 2,3 раза величину перерегулирования для частоты в сети. При этом также уменьшается колебательность частоты в сети. Аналогичные эффекты наблюдаются и в других режимах работы рассматриваемых систем электроснабжения с установками распределенной генерации. Динамическое моделирование подтвердило эффективность использования групповых прогностических регуляторов напряжения и частоты для установок распределенной генерации, заключающуюся в положительном влиянии на качество процессов управления параметрами системы электроснабжения в различных режимах работы.</p></abstract><trans-abstract xml:lang="en"><p>The paper determines the effect of proposed joint voltage and frequency predictive controllers for distributed generation (DG) plants on quality indicators characterizing the control process in different operating modes of power supply systems. The studies are conducted in the MatLab environment (Simulink and SimPowerSystems simulation packages) employing control engineering methods. It is proposed to design and adjust joint predictive controllers by determining the resonant frequency of oscillations for the master generator rotor. This approach provides better quality indicators of voltage and frequency control in power supply systems while maintaining the same settings for the controllers of DG plants. With an additional load in an isolated power supply system, the maximum voltage sag is found to be 1.75 times lower than for local predictive control and 3.5 times lower as compared to the use of conventional controllers. For the specified mode, predictive controllers enable a threefold reduction in the transient time between rotor rotational speeds in a synchronous generator. In the start mode of a powerful electric motor, the predictive controllers of synchronous generators in the power supply system enable a 1.5 times reduction in voltage sag, with a 1.4 times reduction in overvoltage following its start. In the case of a short-term three phase short-circuit, joint predictive controllers allow a 1.5 times decrease in transient time and a 2.3 times decrease in the overshoot of power line frequency as compared to local control. In addition, frequency oscillation in the power system is also reduced. Similar effects are observed in other operating modes of the considered power supply systems equipped with DG plants. The performed dynamic simulation confirms the effectiveness of using joint voltage and frequency predictive controllers for DG plants, which consists in a positive impact on the quality of processes involved in controlling the parameters of power supply systems in various operating modes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>установки распределенной генерации</kwd><kwd>газотурбинная установка</kwd><kwd>малая гидроэлектростанция</kwd><kwd>синхронные генераторы</kwd><kwd>автоматический регулятор скорости</kwd><kwd>автоматический регулятор возбуждения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>distributed generation plants</kwd><kwd>gas turbine</kwd><kwd>small hydro power plant</kwd><kwd>synchronous generators</kwd><kwd>automatic speed regulator</kwd><kwd>automatic excitation regulator</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования выполнены при финансовой поддержке по гранту государственного задания Министерства науки и высшего образования Российской Федерации (проект № FZZS-2020-0039).</funding-statement><funding-statement xml:lang="en">The research was carried out with the financial support under a state assignment grant from the Ministry of Science and Higher Education of the Russian Federation (project No. FZZS-2020-0039).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Fathabad A.
