摘要：

随着交–直–交动车组在电气化铁道中的大量使用,动车组产生的高次谐波引起的牵引网谐波放大、谐振问题越发严峻。针对该问题,本文建立了牵引网的等效电路模型,对牵引网谐振和谐波放大特性进行理论分析和仿真验证,并介绍了一种通过在机车内的牵引变压器辅助绕组上增加高通滤波器来抑制谐波电流增益的方法。最后通过理论计算和仿真验证了该方法抑制谐波增益的有效性,对防止谐波对牵引网造成的危害有一定的参考价值。

Abstract:

With the extensive uses of electric multiple units (EMU) in electrified railway, harmonic resonance problem of traction network resulted from high frequency harmonics generated by electric multiple units becomes more serious. To solve this problem, the equivalent circuit model of traction network is built in the paper to analysis harmonic resonance and amplification characteristics theoretically, and the characteristics by simulations are verified. Thus, a harmonic resonance suppression method is introduced by installing high-pass filter in the locomotive traction transformer secondary winding. A method is presented to select filter element parameters, and the effectiveness of harmonic suppression method are verified through theoretical calculations and simulations, which has reference value for harmonic resonance hazard prevention.

Key words: Traction power supply system, harmonic transmission characteristics, high-pass filter, Matlab simulation
