摘要
基于三相-单相变换器的新型牵引供电系统可彻底取消电分相,全面解决电气化铁路存在的电能质量问题。针对这种新型牵引供电系统中的交直交变电所,设计了一种电力电子变压器结构,可取消输入及输出变压器,PSCAD/EMTDC仿真结果验证了该结构的可行性和有效性。
The new traction power supply system based on three-phase to single-phase converter can completely eliminate neutral section and comprehensively solve the problem of power quality in electrified railway.A power electronic transformer structure is designed for this new traction power supply system,which can cancel the input and output transformers.PSCAD/EMTDC simulation results verify the feasibility and effectiveness of the structure.
