永磁同步电机牵引系统在成都地铁上的应用优化方案研究

Study on Application and Optimizing Scheme of Permanent Magnet Synchronous Motor Traction System in Chengdu Metro

介绍了城市轨道交通行业的节能需求和成都地铁的发展概况,以成都地铁10号线为例阐述了永磁同步电机牵引系统在地铁领域应用的优化设计方案,并分析了永磁同步电机牵引系统在成都地铁的节能经济效益预期。根据仿真计算得出:再生能量充分回馈条件下,永磁牵引列车节能率可达25%～28%。

The energy-saving demand of urban rail transit industry and the development of Chengdu metro was introduced. Taking Chengdu metro line 10 as an example, the optimal design scheme of the application of permanent magnet synchronous motor traction system in metro field was expounded, and the energy-saving and economic benefit expectation of the permanent magnet synchronous motor traction system was analyzed in Chengdu metro. According to the simulation calculation, the energy saving rate of permanent magnet traction train can reach 25%-28% under the condition of full regeneration energy feedback.
