HXD3型电力机车交流传动系统仿真分析

The simulative analysis of HXD3 electric locomotive AC drive system

针对HXD3型电力机车的主传动和辅助传动系统采用了交流传动技术,通过介绍HXD3型电力机车牵引变流器的工作原理,对HXD3型电力机车的主传动系统进行了仿真分析,仿真结果表明基于交-直-交传动方式的牵引变流器应用于机车时具有良好的牵引特性,功率因数高,且谐波干扰小。

Pertaining to the fact that high-power transmission is widely adopted in the main and auxiliary transmission system of HXD3. AC-DC-AC transmission mode is introduced to be applied in the locomotive with the analysis of the simulative results of the four quadrant rectifier and the two levels inverter on the basis of theoretical principles of traction converter in HXD3.The simulation results illustrate that the locomotive boasts of good traction features with high power factor and low harmonic interference.
