交流传动电力机车谐振原因分析与对策

多台HXD1 交流传动电力机车在太原铁路局湖东机务段同时运行时，发生了牵引网和机车变流器谐振现象，致使机车跳闸保护不能正常工作，严重影响了列车调度运行。铁道部专门组织了现场测试。本文对测试结果进行了理论分析分析，找出了谐振的原因，提出了可能的解决办法，并给出了最经济的解决办法。解决的办法被采纳后HXD1 机车与牵引网的谐振问题不再发生。
Abstract : The HXD1 AC locomotives were automatically shut down by protective equipment because of excessive resonant high voltage occurred in DC link of their converters, which originated current resonance between power supply network and the locomotives while couple of them were running simultaneously. This incidents severely impaired locomotives dispatched for freight transportation. This paper presents the analysis and consequent solutions for the resonance based on the on-site data acquisition sponsored and organized by the ministry of railway of China.
