摘要
伴随着国内城市化进程的快速发展,城际交通的需求日渐增长,而动车组以其灵活的编组方式、优良的调速性能成为城际交通的首选。动车组列车牵引变流器中的拍频现象会导致系统损耗增加、发热及机械抖动严重。本文结合单相整流器的结构特性,对拍频现象的来源及其影响进行了分析,综合比较了国内外各种拍频现象的抑制方法,并进行了归纳总结。
With the rapid development of nationwide urbanization, there is a growing demand for intercity transportation. EMU becomes the preferred intercity transport with its flexible marshalling approach and excellent speed performance. Beat phenomenon inEMU traction converters can lead to system loss, severe fever and mechanical shaking. Combined with structural characteristics of single-phase rectifier, sources and influence on the beat phenomenon are analyzed in the paper. The suppression methods of beat phenomenon at home and abroad are compared. The advantages and disadvantages of control modes are summarized.
