大型矿用自卸车交流传动系统的研制

Research on AC Drive System for Heavy Duty Electric Wheel Dump Truck

针对电动轮自卸车的特殊工况,研制了全国产化交流传动系统.介绍了控制系统的基本参数和性能,该系统采用转差矢量控制的控制策略和基于空间矢量(SVPWM)的调制方式.试验表明:该系统启动转矩大,转矩响应迅速,牵引制动平稳可靠,满足大型矿用自卸车交流传动系统设计要求.

According to the special characteristics of heavy duty electric wheel dump truck,the localized AC drive system is developed.Basic parameters and performance of the AC drive system are introduced in this paper.A new method of slip frequency vector control based on space vector PWM is apllied in this system.The resulte of the experiment shows that this AC driver system has good response for the torque and running stability under the traction and brake state,and satisfies the requirements of the AC drive system for heavy duty electric wheel dump truck.
