摘　　要：针对传统矿用蓄电池电机车充电过程繁琐,需将蓄电池从电机车上吊离至专用充电机房充电,再吊回至电机车,这种充电方式要求有多套蓄电池进行替换,效率低下,并且充电纹波大、质量差。对此设计了一种蓄电池电机车车载充电控制系统,采用PWM整流和DC/DC变换两级式拓扑结构,对前级PWM整流器电压外环用线性自抗扰控制,内环采用电流解耦控制,对后级双向DC/DC采用恒流转恒压的双闭环控制。实验结果表明,基于线性自抗扰的车载充电控制系统在提升充电效率的同时,能够有效降低母线电压纹波、减小网侧电流畸变,提高充电质量。In view of the complicated charging process of traditional mining accumulator electric lo-comotive,the battery needs to be lifted from the electric locomotive to the dedicated charging room for charging,and then lifted back to the electric locomotive.This charging method requires multiple sets of batteries to be replaced,which is inefficient,and the battery charging ripple is large and the quality is poor.In this paper,a kind of on-board charging control system for accumulator electric locomotive is designed,which adopt PWM rectifier and DC/DC conversion two-stage topology structure.Linear auto-disturbance rejection control is used for the voltage outer loop of the front stage PWM rectifier,cur-rent decoupling control is used for the inner loop,and constant current and constant voltage double closed loop control is used for the rear stage bidirectional DC/DC.The experimental results show that the charging control system based on linear active disturbance rejection can not only improve the char-ging efficiency,but also effectively reduce the voltage ripple,reduce the current distortion on the grid side,and improve the charging quality.
