Алгоритмические методы обеспечения электромеханической совместимости асинхронных электроприводов при питании от преобразователей частоты

Abstract

A computer model was developed for to research purpose of electromechanical compatibility in asynchronous drive. On the basis of Based on this computer model, the influence of PWM-VSI’s inverter frequency and load value of asynchronous motor shaft load on the level of electromagnetic torque pulsing was investigated. Results of modeling are presented and recommendations for converter’s control algorithms modification, and improving electromechanical compatibility of asynchronous drive, are formulated.

Для исследования электромеханической совместимости асинхронного электропривода разработана компьютерная модель. На компьютерной модели исследовано влияние частоты ШИМ-инвертора и величины нагрузки на валу асинхронного двигателя на уровень пульсаций электромагнитного момента. Приведены результаты моделирования и сформированы рекомендации по модификации алгоритмов управления преобразователем, повышающие электромеханическую совместимость асинхронного электропривода.
