摘要
针对列车辅助供电系统扩展供电和并网供电2种供电方式的优劣,主要介绍了并网供电方式,详细分析了辅助变流器的并网供电分时启动控制算法、中压接触器的控制方法、短路检测流程。此控制算法在某地铁列车上应用稳定,表明中压交流并网供电技术的发展已基本成熟。
Aiming at the advantages and disadvantages of two kinds of power supply modes,i.e.extended power supply and grid power supply,the grid power supply mode was introduces,and the time-sharing start control algorithm of grid power supply of auxiliary converter,the control method of medium voltage contactor and the short circuit detection process were analyzed in detail.The application of the control algorithm in a metro train was stable,which indicated that the development of medium voltage AC grid power supply technology has been basically mature.
