Регулирование механических координат вентильного электропривода методом векторного управления

Регулирование механических координат вентильного электропривода методом векторного управления

Abstract

Рассматриваются вопросы регулирования скорости вращения и электромагнитного момента в вентильном электроприводе, построенном на основе синхронного двигателя с возбуждением от постоянных магнитов. Приводятся аналитические соотношения, определяющие закон изменения угла коммутации исходя из условий обеспечения заданного значения регулируемых координат или максимального значения электромагнитного к.п.д. Показано качественное и количественное отличие электромагнитного к.п.д., учитывающего электрические потери, и полного к.п.д., определяемого отношением электромагнитной к полной потребляемой мощности.

The article is devoted to regulation of speed and torque of Synchronous Motor with Permanent Magnet. The law of change of switching angle is received from conditions of support of the preset value of adjustable coordinates or the maximum value of electromagnetic efficiency. Qualitative and quantitative difference of electromagnetic efficiency from full efficiency is received. Theoretical provisions are supported by specific calculations and computer simulation.
