摘要:
城市轨道交通混合供电系统为双向变流器机组和二极管整流机组并联工作的供电系统。二极管整流机组输出电压不可控，无法根据现场工况变化进行调整；双向变流器采用全控型器件，可通过参数调整实现多种输出特性。在混合供电系统中，双向变流器需根据不同的控制目标及二极管整流机组输出特性等因素对自身输出特性进行调整。针对混合供电系统中双向变流器输出特性设计方法进行研究，实车测试结果表明，混合供电系统能满足各种供电模式的实际应用需求，也能实现双向变流器与整流机组之间的协同工作。
Abstracts:
Urban rail transit hybrid power supply system is a parallel-working power supply system, which consists of bidirectional converter unit and diode rectifier unit. The output voltage of the diode rectifier unit is uncontrollable and nonadjustable to the changes of field working conditions, while the bidirectional converter can realize various output characteristics through parameter adjustment by adopting the fully controlled apparatus. In hybrid power supply system, the bidirectional converter needs to adjust its output characteristics according to different control objectives and output characteristics of the diode rectifier unit. The design method of bidirectional converter output is studied according to the characteristics of hybrid power supply system, and the test result of actual vehicles shows that the system can meet the application demands under all kinds of power supplying modes, and achieve the coordination between bidirectional converter and rectifier unit at the same time.
