双源制机车蓄电池模式下辅助系统控制优化

Control optimization of auxiliary system in dual source locomotive battery mode

新型双源制机车采用“接触网+蓄电池”双供电系统,能自由穿梭于有接触网区和无接触网区。基于靖神双源制机车的主辅电路的设计及工作原理,讨论蓄电池模式下机车辅助系统的控制优化。通过对辅逆模式及辅助负载的控制,使蓄电池模式下的机车控制方式更加合理、更加节能。

The new dual source locomotive adopts catenary+battery dual power supply system,which can shuttle freely between the area with catenary and the area without catenary.Based on the design and working principle of the main and auxiliary circuit of Jingshen dual source locomotive,this paper discusses the control optimization of locomotive auxiliary system in battery mode.Through the control of auxiliary reverse mode and auxiliary load,the locomotive control mode in battery mode is more reasonable and energy-saving.
