电力电子技术的发展给直流传动技术带来新的发展机遇,目前,工矿直流1500V电力机车速度控制系统,一般采用多台驱动电机串、并联,用增减串联电阻多少来控制电机车的速度。其缺点是能耗
The development of power electronic technology brings new development opportunities to DC drive technology. At present, the speed control system of industrial and mining direct current 1500V electric locomotive generally adopts multiple drive motor strings and parallel connections, and controls the speed of the electric motor car with increasing or decreasing series resistance. The disadvantage is energy consumption
