- Abstract
The pantograph-catenary offline has many adverse effects on the safe operation of the subway. Firstly, the simulation model of pantograph-catenary offline traction system was established, and then the offline conditions of different durations were simulated. By analyzing the transient process of the DC side voltage, IGBT voltage and motor rotor current of the traction inverter circuit during the offline period, the differential effects of different offline time lengths on the electrical characteristics of the train traction process were obtained. The results have a good theoretical guiding role for the fault diagnosis of the traction system and the formulation of maintenance strategies.
