城轨车辆永磁同步牵引系统的仿真研究

Simulation Research on Permanent Magnet Synchronous Traction System of Urban Rail Vehicle

以某地铁10号线地铁车辆为技术平台,对永磁同步牵引系统在地铁领域应用进行研究。对整车总体技术指标、牵引特性曲线、牵引传动系统主电路及相关控制策略进行介绍,并通过建模仿真验证了永磁同步牵引系统及其控制策略等关键技术的可靠性。

In this paper,a metro line 10 subway vehicle was used as a technology platform to study the application of permanent magnet synchronous motor traction system in the subway field.The overall technical indicators of the vehicle,the traction characteristic curve,the main circuit composition of the traction drive system,and the control strategy of the permanent magnet synchronous motor were introduced.Simulation verification showed that the key technologies such as the permanent magnet synchronous traction system and its control strategy were reliable and could achieve the expected goals.
