摘要
通过对大容量柔性直流牵引供电方案仿真研究及其节能效果评估研究,提出2种大容量柔性直流牵引供电方案:(1)整流+变流一体化方案;(2)高频一体化整流/逆变双向变流方案。并完成整流和再生回馈一体化的柔性直流牵引供电装置研发及样机试制,目前正在进行样机挂网试验工作。
Based on the simulation study of large capacity flexible DC traction power supply scheme and energy-saving effect evaluation study,this paper proposes two kinds of large capacity flexible DC traction power supply schemes:(1)rectifi er+converter integration scheme,(2)high frequency integrated rectifier/inverter bidirectional converter scheme.It has completed the research and development of fl exible DC traction power supply device integrating rectification and regeneration and feedback and prototype trial production.At present,the prototype test with OCS is in progress.
