| 摘 要： | 提出了基于YN,3d-1变压器并结合两单相变流器和自耦变压器(AT)的供电方式。它实现了同相牵引供电,牵引变电所一次侧不再轮换,变电所单相供电,不用设置分相绝缘器;通过实时检测系统的综合补偿电流控制变流器,平衡三相,动态滤除无功和谐波电流。讨论了其补偿原理,给出了指令电流检测和变流器控制方法。分析和仿真证明,该同相供电系统是可行的。

| Abstract: | It presents a power supply method based on YN, 3d -1 transformer, which combines with two single-phase converters and an autotransformer (AT). It achieves the cophase traction power supply. The primary side of traction substation will not be exchanged anymore, and the single phase power supply is applied without setting any neutral section insulator. The converter is controlled by comprehensive compensating current of real time detecting system, so that the three-phase is balanced, and the reactive and harm... |
