交直交电力牵引谐波的影响与改进

Impact of AC-DC-AC electric traction harmonic and its improvement

测试结果表明交直交动车组、大功率电力机车与传统电力机车相比最显著的特征是其谐波特性不同,对牵引供电系统、动车组的影响较大。本文列举上海铁路局管内交直交电力牵引负荷的谐波特性及其对牵引供电系统、动车组的影响,经研究试验采用了相应技术措施进行改进,确保牵引供电系统和动车组的正常运行。

Test results show that the AC-DC-AC EMUs, high-power electric locomotive, compared with the traditional electric locomotive, a notable feature is the distinct character of its harmonics, the impact of harmonics on the traction power supply system and EMU is larger, it’s a new subject, this article lists the characteristics of harmonics in AC-DC-AC electric traction which belongs to Shanghai Bureau, and lists the impact on the traction power supply system and EMU, the corresponding technical measures was taken to make improvements by research and test, it ensure the normal operation of the traction power supply system and EMU.
