| 摘 要： | 传统的直接转矩控制算法,限制了电力机车在低速段的控制性能。介绍了一种基于定子磁链定向的直接转矩控制算法,并结合三电平逆变器SVPWM调制算法,有效减小了转矩的波动,降低了电流谐波的含量,提高了电力机车的控制性能。通过仿真比较,证明了该方法的合理性和有效性。

| Abstract: | The traditional direct torque control algorithm limits the performances of electric trains in the low-speed segment.This paper describes a direct torque control algorithm based on the stator flux-oriented method,combined with three-level inverter SVPWM modulation strategy.It effectively reduces the torque ripple,weakens the harmonic currents,and increases the control performance of locomotives.The results show that this method is reasonable and effective. |
