Экспериментальное исследование двенадцатифазного компенсированного выпрямителя с векторным управлением

Abstract

Проведено экспериментальное исследование двенадцатифазного компенсированного выпрямителя с фильтрацией в коммутирующие конденсаторы нечетно-кратных гармоник входных токов шестифазных вентильных блоков в случае векторного управления. Исследование выполнено с использованием оборудования лабораторного стенда, подключенного к сети внутреннего электроснабжения университета. Напряжение управления, вносимое последовательно с напряжением питающей сети, создавалось посредством применения индукционного регулятора. Продемонстрировано качественное соответствие электромагнитных процессов, протекающих в преобразователе, полученной ранее теории преобразователя с векторным управлением. Получены экспериментальные внешние и энергетические характеристики выпрямителя. Проведенная статистическая обработка экспериментальных данных показывает качественное соответствие теории и эксперимента. Сделан вывод о том, что векторное управление эквивалентно подключению преобразователя к источнику с регулируемыми амплитудами и фазами питающих напряжений.

An experimental investigation of twelve-phase compensated rectifier with vectorial control was realized. The investigation was delivered by means of using laboratory equipment connected to an university’s mains supply. The rectifier has a compensating device that filters in the commutating capacitors odd-multiple harmonics of rectifier assemblies’ input currents. A control voltage that summarized with a mains supply voltage is created by means of using a induction voltage regulator. A qualitative equivalence between experimental rectifier’s electromagnetic processes and the theory of converter with vectorial control was shown. Experimental rectifier’s output and power performances were obtained. A statistical treatment of experimental data shows a qualitative equivalence between the theory and the outcome of experiment. The vectorial control is an equivalent of supplying the rectifier by a power source with adjustable amplitudes and phases of its voltages.
