The invention provides an auxiliary inverter control method and system and a train. The method comprises the steps that the real-time capacity of each auxiliary inverter is obtained; on the basis of the obtained real-time capacity of each auxiliary inverter, the working efficiency under each real-time capacity in the working efficiency curve of the auxiliary inverter is searched, and the sum of the optimal efficiency is obtained; and controlling the output efficiency of each auxiliary inverter based on the sum of the optimal efficiency. The auxiliary inverter works in the optimal efficiency interval, and meanwhile, a polling working mechanism based on temperature is given, so that the energy consumption of the train is reduced, the availability of the train is ensured, and the working aging of components is reduced.

    本发明提供了一种辅助逆变器控制方法、系统及列车,包括:获取每个辅助逆变器实时容量;基于获取的每个辅助逆变器实时容量,查找辅助逆变器工作效率曲线中每个实时容量下的工作效率,得到最优效率之和;基于最优效率之和控制每个辅助逆变器的输出效率。通过使辅助逆变器工作在最佳效率区间,同时给出一种基于温度的轮询工作机制,降低列车能耗、保证列车可用性、降低元器件工作老化。
