Abstract：Because of the several inherent technic advantages of AT(Auto-Transformer) power supply, it has become the first choose for high speed train and heavy-haul train ,this paper aims at various of AT power supply which setting up Auto-transformer at the export of substation or not and different substation voltage, analyzed and simulation it’s impedance characteristics,current distributing of normal operation and short-circuit current carefully.This paper’s theoretic analyze will provide directly instruct for practical project application.
