多臺(tái)HXD1 交流傳動(dòng)電力機(jī)車在太原鐵路局湖東機(jī)務(wù)段同時(shí)運(yùn)行時(shí)，發(fā)生了牽引網(wǎng)和機(jī)車變流器諧振現(xiàn)象，致使機(jī)車跳閘保護(hù)不能正常工作，嚴(yán)重影響了列車調(diào)度運(yùn)行。鐵道部專門組織了現(xiàn)場(chǎng)測(cè)試。本文對(duì)測(cè)試結(jié)果進(jìn)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(jīng)濟(jì)的解決辦法。解決的辦法被采納后HXD1 機(jī)車與牽引網(wǎng)的諧振問題不再發(fā)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.
