多模塊互聯(lián)電力電子系統(tǒng)穩(wěn)定性和動(dòng)態(tài)特性研究進(jìn)展

由多個(gè)具有獨(dú)立和完整功能的電力電子變流器通過(guò)相互級(jí)聯(lián)和并聯(lián)的方法連接起來(lái)，已經(jīng)成為構(gòu)成現(xiàn)代各種先進(jìn)的復(fù)雜電力電子系統(tǒng)的基本形式。現(xiàn)有的電力電子技術(shù)體系大都是討論單個(gè)變流器與簡(jiǎn)單特性的電源或負(fù)載之間的相互作用并進(jìn)行相應(yīng)的分析和設(shè)計(jì)的，對(duì)多模塊（變流器）互聯(lián)而成的電力電子系統(tǒng)中變流器之間的相互作用（包括級(jí)聯(lián)時(shí)電源變流器和負(fù)載變流器之間的相互作用、并聯(lián)變流器之間的相互作用等）以及由這種相互作用表現(xiàn)出來(lái)的整個(gè)電力電子系統(tǒng)的特性，亟待進(jìn)行深入的認(rèn)識(shí)和研究。本文將概述在多模塊互聯(lián)電力電子系統(tǒng)的穩(wěn)定性和動(dòng)態(tài)特性領(lǐng)域國(guó)際上近年來(lái)的發(fā)展歷史和現(xiàn)狀，并匯報(bào)總結(jié)作者所在的課題組近年來(lái)在該領(lǐng)域所取得的成果。
Abstract: Cascading and/or paralleling multiple power converters have become a common method to constitute all kinds of advanced power electronics systems. Current techniques and knowledge system of power electronics is mainly addressing interactions between a power converter and an ideal power source or load. There is a tremendous need to
understand and investigate interactions among power converters in a multi-module power electronics system, including the
interactions between source converters and load converters in cascaded connection, and the interactions among paralleled
power converters. The need is solidly extended to explore the system level performance of multi-module power electronics
systems. This paper reviews and summarizes research advances in this area around the world as well as reports recent progresses made by the authors’ research team.
