Анализ энергетических характеристик высоковольтных преобразователей частоты для регулирования скорости турбокомпрессоров

Abstract

The analysis of the topology features and power characteristics of modern high-voltage converters of frequency is presented. The features of the circuit structures and the functional capabilities of multilevel converters of domestic production for power efficiency and reliability increase of electric drives have been considered. There conducted the simulation of a harmonic composition of output voltage and current of highvoltage converters of frequency and received the oscillograms of output characteristics and harmonious spectra of the parameters of 5 most typical structures of converters of frequency at the work for an active-inductive loading The results of calculation of the factors of distortion of output voltage and current and the corresponding levels of spectra of the frequencies have been presented.

Представлен анализ особенностей топологии и энергетических характеристик современных высоковольтных преобразователей частоты для электроприводных компрессорных станций. Рассмотрены особенности схемных структур и функциональных возможностей многоуровневых преобразователей отечественного производства для повышения энергоэффективности и надежности электроприводов. Проведено моделирование гармонического состава выходного напряжения и тока высоковольтных преобразователей частоты и получены осциллограммы выходных характеристик и гармонические спектры параметров 5 наиболее типичных структур преобразователей частоты при работе на активно-индуктивную нагрузку. Представлены результаты расчета коэффициентов искажения выходного напряжения и тока и соответствующие уровни спектров частот.
