摘　　要：研究了300t电动轮自卸车交流传动系统的主电路、控制单元及控制策略,以此为基础研制了完全自主化的交流传动系统,该系统牵引电机转矩采用基于特定谐波消除PWM(SHEPWM)的矢量控制,发电机励磁采用电压电流双闭环控制.通过型式试验及运行考核表明:该完全自主化的交流传动系统能很好满足300t矿用自卸车的应用需求.This paper presents the power circuit ＆ general structure and the control unit of traction invert- er and it＇s control strategy in 300T heavy duty electric wheel dump truck. Based on the analysis, an com- pletely Sel-Development AC drive system is developed. A new method of vector control based on selected harmonic elimination and a double voltage and current closed-loop generator excitation control strategy is applied to this system. The result of the experiment shows that this AC drive system satisfies the require- ments of the 300T heavy duty electric wheel dump truck.
