摘要
主要从提高列车辅助供电系统的可靠性、稳定性及系统冗余度的角度,介绍分析了辅助供电系统的并网供电设计方案和接地故障策略,并结合现有车辆辅助供电系统存在的问题,通过对控制电路进行了改进设计,实现了既定的接地策略。
This paper mainly from the increase of train auxiliary power system reliability,stability and system redundancy perspective,and introduces and analyzes the design of grid connected power supply auxiliary power supply system and grounding fault strategy,combining the existing auxiliary power supply system of the existing vehicle problems,by improving the design of the control circuit.The established grounding strategy is realized in this paper.
