| 摘 要： | 针对电气化铁道牵引供电系统三相严重不平衡造成各供电区段需要用分相绝缘器分断,从而制约了高速、重载铁路的发展,提出了一种基于斯科特变压器的新型同相AT牵引供电系统,阐述了平衡变换原理及控制和补偿电流实时检测方法,仿真证实该文提出的平衡方式、检测与控制方法是正确的,同相供电系统方案切实可行。

| Abstract: | The phase seperation insulator is necessary due to the seriously unbalanced 3 phases of the traction power supply system for the electrified railway. Thus the development of high-speed and heavy-load railways is restrained. As a solution, a new cophase AT traction power supply system based on Scott transformer is proposed. The balance conversion principle and the real-time testing method of control & compensation current are explained. The simulations prove that the proposed methods of balance, detection and control are correct and that the program of the cophase power supply system is rational and practicable. |
