【摘要】 随着交流传动调速技术的不断发展,直接转矩控制技术得到越来越多的关注,其在交流调速领域得到了广泛的应用。本文通过对城市轨道交通车辆的牵引/制动特性曲线,牵引电机、牵引逆变器进行设计,详细介绍了牵引系统的设计过程,最后以成都地铁1号线车辆为例,通过基于城轨车辆的直接转矩控制系统建模仿真,说明了直接转矩控制在城市轨道车辆上的优越性。更多还原

【Abstract】 With the continuous development of AC speed regulation,direct torque control technology has been paid more and more attention,which has been widely applied in this field.Based on the urban rail transit vehicles traction / braking characteristics,traction motors,traction inverter design,detailing the traction system design process.Then take Chengdu Metro Line 1 for example,compared the simulations between DTC and VC based on urban rail vehicles,shows the superiority of direct torque control on urban rail vehicles.更多还原
