| 摘 要： | 变频调速系统输出的脉宽调制波含有丰富的谐波,谐波引起附加损耗,使交流牵引电机运行温升增加,导致绝缘加速老化,缩短其运行寿命.文章利用MATLAB软件建立了变频调速仿真系统,对影响变频牵引电机谐波损耗的逆变器参数进行了分析,并提出一种用谐波总损耗因数表征谐波损耗的方法.

| Abstract: | This paper focuses on the influence of frequency control system on harmonic losses of traction motors.Output of the inverter in frequency control system contains a great quantity of harmonics,which will give rise to extra losses that are harmful to the insulation of traction motors.Using MATLAB,the frequency control equivalent model is developed based on the principle of sinusoidal pulse width modulation(SPWM).The harmonic spectrum of steady-state operation is simulated using this model.The influence of the following inverter parameters is considered:modulation index and switch frequency.HLF is defined and used to represent the harmonic losses. |

| Keywords: | inverter traction motor harmonic loss factor(HLF) total harmonic distortion(THD) |
