摘　　要：城际动车组的大量投入使用,使电气化铁路牵引供电系统发生谐波谐振,严重损坏车载设备以及地面设备,因此有必要深入研究“车-网”系统下的谐波问题。为此,基于相关国家电能质量标准,采用广域分布式电能质量监测系统,对国内某城际动车组与牵引变电所展开同步测试,定量评估不同运行工况下整车谐波电流发射特性。此外,基于车辆运行期间牵引变电所馈线谐波电流,评估城际动车组谐波在牵引供电系统中的传递特性与分布规律。The large increase in newly operating intercity EMU leads to harmonic resonance of electric railway traction power supply system,poses serious damage to on-board and ground equipment,and hence highlights the necessity of deepened investigation on harmonic problem in the"vehicle-network"system.Therefore,based on the relevant national power quality standards and by applying wide-area distributed power quality monitoring system,this work conducts synchronous tests on a domestic intercity EMU and traction substation to quantitatively evaluate harmonic current emission characteristics of the whole vehicle under different operating conditions.In addition,based on the harmonic current in the feeder line of traction substation during vehicle operation,the transmission characteristics and distribution law of harmonics in the traction power supply system of intercity EMU are evaluated.
