摘　　要：电力推进已经成为破冰船等船舶的主要推进方式,并且将直接转矩控制作为推进电动机的主要控制方法。本文以雪龙2号极地考察船为例,介绍了ABB公司回转型电力推进系统中ACS6000变频器的特点,分析了直接转矩控制的原理。通过驱动无刷励磁同步电机的负载阶跃实验,证明了直接转矩控制具有动态速度响应迅速和动态速度误差小的特点。Electric propulsion has become the main propulsion mode of icebreaker and others, and direct torque control is the main control method of propulsion motor. Taking the Snow Dragon Ⅱ Polar Survey Vessel as an example, this paper introduces the characteristics of ACS6000 converter in rotary electric propulsion system of ABB Company, and analyses the principle of direct torque control. Through the step response test of the load of driving brushless excitation synchronous motor, it is proved that direct torque control has the characteristics of fast dynamic speed response and small dynamic speed error.
