摘要
神华号电力机车为神华集团主力运输车型之一,采用交直交型传动系统,功率大、功率因数高,但谐波频谱更宽,其谐波特性与传统货运交直型电力机车有明显区别。通过建立牵引供电系统和神华号电力机车仿真模型,对不同工况下神华号电力机车谐波特性进行分析,并得出结论,为谐波治理提供参考。
Shenhua electric locomotives are one of the types of main transportation vehicles for Shenhua Group, the locomotives, equipped with AC DC AC driving system, are of high power, high power factor and wider harmonic spectrum, and the harmonic characteristics are quiet different to those of traditional AC DC electric locomotives for freight transportation. The simulation models of traction power supply system and Shenhua electric locomotive are established for analyzing of harmonic characteristics with Shenhua locomotives being under various working conditions, the conclusions are obtained and will be providing references for control of harmonics.
