摘　　要：基于我国电气化铁路近年来的快速发展,供电系统和机车之间的车网谐振问题越发突出。哈大线山海关站、哈尔滨站,大秦线,西安恒口变电站都发生过车网谐振造成的避雷器炸裂、中断区间供电等故障。针对铁路牵引供电系统以及电力机车四象限控制进行研究,实测了西安恒口变电站HXD21000型交流传动货运机车各种工况下车网谐振频率和幅值,经过对测试数据和HXD21000型交流传动货运机车四象限控制分析,提出了系统解决车网谐振问题的方法。With the rapid development of electrified railways in China in recent years,the problem of the resonance between supply network and locomotives(vehicle-network resonance)has become increasingly acute.The lightning arrester crack,interruption of section power supply and other failures caused by vehiele-network resonance occurred at Shanhai Pass station and Harbin station of the Harbin-Dalian line,the Datong-Qinhuangdao line and the Hengkou substation in Xi-an.Therefore,we studied the railway traction power supply system and the four quadrant control of electrie locomotives and measured the resonance frequency and amplitude of the HXD21000 AC freight locomotive under various working conditions at the Hengkou substation.At the basic of analyzing the lest data and the four quadrant control of the HXD21000 AC freight locomotive,we.proposed a systematie solutions to the problem of vehicle-network resonance.
