摘要
文中对城市轨道交通双向牵引供电系统进行深入研究,针对双向变流装置与二极管整流机组并联运行时功率分配问题,双向变流装置绕组间环流问题及输出电能质量问题,重点研究基于三电平拓扑结构下桥臂并联的主回路拓扑,提出基于电流PR的控制策略,算法实现相对简单,最后在厂内搭建基于10 kV能量内循环的整机试验平台,验证了该算法的有效性。
In this paper,an in⁃depth study of the bidirectional traction power supply system for urban rail transit is carried out.In view of the power distribution problem when the bidirectional converter device and the diode rectifier unit are operated in parallel,the circulation current problem between the windings of the bidirectional converter device and the output power quality problem,this paper focuses on the main loop topology of the bridge arms in parallel under the three⁃level topology structure.A control strategy based on current PR is proposed,and the algorithm is relatively simple for implementation.A whole machine test platform based on 10 kV energy internal circulation is built in the factory,which verifies the effectiveness of the proposed algorithm.
