摘要:
随着全国城市轨道交通线网规模的不断扩大，列车再生制动能量的有效利用问题也日益被关注。宁波轨道交通集团有限公司创新地研发了双向变流器牵引供电技术，该技术将牵引变电所整流机组的整流供电和能馈装置的逆变回馈功能合二为一，通过运营线路挂网试运行、实车测试，验证了双向变流器牵引供电技术优势突出，经济及社会效益亦较为明显。
Abstracts:
With the continuous expansion of national urban rail transit network, the effective utilization of train regenerative braking energy has become a rising concern. Ningbo Rail Transit Group Co., Ltd. has creatively developed a traction power supply technology with bidirectional converter, which combines the rectifier power supply of traction substation with the inverter feedback function of the energy feedback device. Through trial run on the operation line, actual vehicle test and verification, the technical advantages of bidirectional converter are verified, the economic and social benefits generated by the bidirectional converter are obvious.
