合蚌客专牵引变压器选型

Traction Transformer Selection for Hefei-Bengbu Dedicated Passenger Line

通过分析VX接线变压器接线原理和结构特点,可知其适用于合蚌客专自耦变压器和直供合用的牵引变电所。对所采用的VX变压器原边绕组及次边T、F绕组容量进行了配置。为了减少牵引负荷对电力系统负序影响,研究了合蚌客专牵引变压器换相联接的方法,并通过MATLAB/Simulink进行了建模和仿真。

By analyzing the wiring principle and structure characteristics of VX connection transformer, it is found that VX wiring is suitable for the traction substation in Hefei-Bengbu Dedicated Passenger Line, the power supply method of which can both adopt direct power supply and power supply from AT. The original side winding and the secondary side T and F winding capacity of the VX transformer are configured. In order to reduce the negative sequence influence of traction load on the power system, phase alternating connection method in the traction transformer of Hefei-Bengbu Dedicated Passenger Line is studied, and modeling and simulation are carried out with MATLAB/Simulink.
