摘要

为了提高新能源电动汽车的续航里程，解决低速行驶阶段电力传动系统效率低的问题，提出了一种空间矢量脉宽调制算法。利用Matlab/Simulink软件建立仿真模型，分析新能源电动汽车实际行驶过程中电力传动系统的试验参数，探讨电力传动系统线路电压的谐波分布以及电池母线电压对谐波含量的影响。实际测试结果表明，在实际电力传输情况下，减小母线电压与基线电压之差可以降低谐波含量，提高系统效率。根据发电系统的特点，提出了一种可靠的电机优化方案，以降低谐波含量，提高新能源汽车电力传动系统的效率。

Harmonic Analysis of Electric Transmission System of New Energy Vehicle

In order to improve the cruising range of new energy electric vehicles and solve the low efficiency of electric transmission system in low-speed driving stage, a space vector pulse width modulation algorithm is proposed. The simulation model is established by Matlab/Simulink software, and the test parameters of electric transmission system in the actual driving process of new energy electric vehicle are analyzed, and the harmonic distribution of line voltage of electric transmission system and the influence of battery bus voltage on harmonic content are explored. The actual test results show that reducing the difference between the bus voltage and the fundamental line voltage under actual electric transmission can reduce the harmonic content and improve the system efficiency. According to the characteristics of power generation system, a reliable motor optimization scheme is proposed to reduce harmonic content to improve the efficiency of electric transmission system of new energy vehicles.
