Driving control system for mine electric vehicles

Abstract

A drive controlling system of electric locomotive for mining shaft is composed of a rechargeable supper capacitor set as power supply, a single switching magnetoresistance motor as the drive motor, an energy controller for quickly recovering the regenerated electric energy to said super capacitor set when the electric locomotive is braking and is in electric generation state, a motor controller, and a master controller communicated via CAN but to said motor and energy controllers.

Description

Technical field: [0001] The invention relates to a drive control system for the operation of a mine electric locomotive, in particular replacing a traditional storage battery with a supercapacitor and replacing a brushed DC motor with a brushless switched reluctance motor control system, belonging to the technical field of electric drive control for mine electric locomotives . Background technique: [0002] Coal is currently the most important energy pillar in my country, and mine electric locomotives are important equipment for coal mine transportation. Existing mine electric locomotive is divided into two kinds, and a kind of is battery electric locomotive, and another kind is wire type mine electric locomotive. For high-gas mines, battery electric locomotives must be used because overhead electric locomotives are not allowed. In addition, the existing electric locomotives are mainly driven by brushed DC motors, and there are also a small number of vehicles driven by AC ...

AI Technical Summary

Problems solved by technology

[0004] 1) Wire-type mine electric locomotives are not allowed to be used in high-gas mines;

[0005] 2) Battery electric locomotives have low efficiency in energy conversion and system operation, and the battery life is short and the maintenance is heavy, causing high costs and increasing coal costs;

[0006] 3) Each locomotive needs to be equipped with two motors, which are expensive and complex in structure;

[0007] 4) When the DC motor is driven, due to the mechanical commutation and carbon brush, the maintenance amount is large and the replacement is frequent;

[0008] 5) The underground explosion-proof requirements and the humid working environment are not conducive to the heat dissipation of the motor, and the rotors of the DC motor and the AC induction motor both generate heat, which requires high heat dissipation for the motor
