        <p>Показана актуальность и необходимость выбора и обоснования структур гибридных фильтрокомпенсирующих устройств на основе последовательных и параллельных активных фильтров для повышения качества электроэнергии в системах электроснабжения предприятий минерально-сырьевого комплекса. Разработаны математические модели гибридных фильтрокомпенсирующих устройств на основе параллельного и последовательного активных фильтров. На основе данных математических моделей разработаны компьютерные имитационные модели указанных гибридных структур. Результаты имитационного моделирования показали эффективность коррекции показателей качества электроэнергии в части снижения уровня высших гармоник тока и напряжения, а также отклонений напряжения. Выявлены степени влияния фильтрокомпенсирующих устройств на показатели качества электроэнергии, определяющие непрерывность и устойчивость технологического процесса на предприятиях минерально-сырьевого комплекса. Установлено, что гибридное фильтрокомпенсирующее устройство на базе параллельного активного фильтра позволяет снизить уровень высших гармоник тока и напряжения более чем на 90 и 70 % соответственно, а на основе последовательного активного фильтра – снизить уровень высших гармоник напряжения более чем на 80 %. По результатам моделирования выявлена возможность компенсации реактивной мощности гибридной структуры на основе параллельного активного и пассивных фильтров. Обоснована возможность интеграции гибридных фильтрокомпенсирующих устройств в более сложные многофункциональные электротехнические комплексы автоматизированного повышения качества электроэнергии, а также целесообразность и перспективность их использования в системах комбинированного электроснабжения на основе параллельной работы централизованных и автономных источников распределенной генерации.</p>

        <p>The urgency and necessity of choosing and justifying the structures of hybrid filter-compensating devices based on series and parallel active filters to improve the quality of electricity in the power supply systems of enterprises of the mineral resource complex is shown. Mathematical models of hybrid filter compensating devices based on parallel and series active filters have been developed. Based on these mathematical models, computer simulation models of the indicated hybrid structures have been developed. The results of simulation showed the effectiveness of the correction of power quality indicators in terms of reducing the level of higher harmonics of current and voltage, as well as voltage deviations. The degree of influence of filter-compensating devices on the power quality indicators, which determine the continuity and stability of the technological process at the enterprises of the mineral resource complex, have been revealed. It has been established that a hybrid filter-compensating device based on a parallel active filter can reduce the level of higher harmonics of current and voltage by more than 90 and 70 %, respectively, and based on a series active filter, it can reduce the level of higher harmonics of voltage by more than 80 %. Based on the simulation results, the possibility of compensating for the reactive power of a hybrid structure based on parallel active and passive filters has been revealed. The possibility of integrating hybrid filter-compensating devices into more complex multifunctional electrical systems for the automated improvement of the quality of electricity is substantiated, as well as the expediency and prospects of their use in combined power supply systems based on the parallel operation of centralized and autonomous sources of distributed generation.</p>
