多臺HXD1 交流傳動電力機車在太原鐵路局湖東機務段同時運行時，發生了牽引網和機車變流器諧振現象，致使機車跳閘保護不能正常工作，嚴重影響了列車調度運行。鐵道部專門組織了現場測試。本文對測試結果進行了理論分析分析，找出了諧振的原因，提出了可能的解決辦法，并給出了最經濟的解決辦法。解決的辦法被采納后HXD1 機車與牽引網的諧振問題不再發生。
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.
