轨道交通永磁同步牵引系统的发展概况及应用挑战

Development Overview and Application Challenges of Permanent Magnet Synchronous Traction System for Rail Transit

永磁同步牵引系统在轨道交通领域已逐步进入到工程化和商业化应用阶段。株洲南车时代电气股份有限公司在沈阳地铁上首先实现了该系统的装车试验,对于我国轨道交通牵引系统技术的自主创新具有积极而深远的意义。文章在简要介绍国内外轨道交通永磁同步牵引系统发展技术现状的基础上,阐述了该系统的技术优势及态势,同时阐明其在轨道交通领域内的应用挑战,为该系统的发展提供一定的参考。

Permanent magnet synchronous motor （PMSM） traction system in rail transit has gradually entered into engineering and commercialization application stage. Zhuzhou CSR Times Electric Co., Ltd. has achieved field trial of PMSM traction system on Shenyang Metro in China firstly, which has a positive and profound significance for the innovation of China＇s rail transit traction system technology. This paper introduces the status of the domestic and international development of PMSM traction system in rail transit. The merits and application characteristics are introduced, and the application challenges are also presented, which provides a reference for the development of PMSM traction system in rail transit.
