摘要
通过对辅助电源系统进行了详细的研究,确定了110V低压回路建模所需要的参数,并获取了相应的有效参数,通过Saber仿真软件对地铁列车低压回路接地进行模拟研究,最后分析比较了低压回路接地电阻法和接地开关法的优劣。
Through a detailed study of the auxiliary power supply system,the parameters required for the modeling of the 110 V low-voltage circuit are determined,and the corresponding effective parameters should are obtained.The simulation of the grounding of the low-voltage circuit of the subway train is carried out by Saber simulation software.Finally,the advantages and disadvantages of the low-voltage loop grounding resistance method and the grounding switching method is compared.
