中低速磁浮逆变回馈型再生制动组合变流装置应用

Application of Inverter Feedback Regenerative Braking Combined Converter for Medium and Low Speed Maglev

目前国内城市轨道交通主要采用独立于整流机组的再生制动变流器与再生制动隔离变压器组合的中压逆变能馈方案。本文结合凤凰磁浮文化旅游项目一期工程,阐述了基于独立的整流模块与双向逆变模块构成的组合变流装置在中低速磁浮项目中的应用。随着凤凰磁浮一期线路的试运营,该组合变流装置已取得预期效果,以期对后期中低速磁浮轨道交通供电设计提供参考。

At present,the domestic urban rail transit mainly adopts the scheme of medium voltage inverter energy feedback composing of regenerative braking converter independent of rectifier unit and regenerative braking isolating transformer.The paper,with connection to the First Phase of Fenghuang Maglev Express Cultural Tourism Project,illustrates the application combined converter device composed of independent rectifier modules and bidirectional inverter modules in medium and low speed maglev project.With the trial operation of the line of the first phase of Fenghuang Maglev Express,the combined converter device has achieved the expected results.It is expected to provide reference for design of medium and low speed maglev rail transit in the future.
