Description

technical field [0001] The invention relates to the technical field of electric locomotive traction control, in particular to an intelligent high-efficiency electric locomotive traction drive control system and a method thereof. Background technique [0002] Electric locomotive is a traditional equipment of industrial and mining enterprises, mainly used for mining or tunnel operations. According to the power supply method, it can be divided into: wire electric locomotive, battery electric locomotive; according to the traction force, it can be divided into: 5t, 8t, 12t, 20t, 24t series electric locomotive; according to the speed regulation method, it can be divided into: DC traction motor series resistance speed regulation, DC traction motor chopper speed regulation, AC traction motor frequency conversion speed regulation. Judging from the trend of technological development: trolleys and battery trolleys will develop in parallel, and battery trolleys with larger tonnage (12t...

AI Technical Summary

Problems solved by technology

The outstanding problems of this system are: first, the starting voltage of the electric locomotive fluctuates greatly, which damages the battery; Group charging affects the life of the battery pack; third, with the operation of the electric locomotive, the voltage of the battery gradually decreases, which affects the operating efficiency of the electric locomotive; fourth, the excessive frequency of starting and braking of the electric locomotive, and heavy-duty operation damage the battery and reduce the The efficiency of the battery; Fifth, the intelligent identification, location tracking, and fault diagnosis capabilities of electric vehicles are insufficient
