自2007年,以HXD1型机车投入运用为标志,我国电气化铁路牵引动力开始了“交—直”传动向“交—直—交”传动转化的进程。目前,已有超过4 500台交流传动电力机车投入运营。随着交流传动电力机车的大量投入使用,一方面极大地提高了铁路运输效率和质量,另一方面也给电气化线路带来了谐波谐振的问题,影响系统的稳定和安全运行。文章阐述了HXD1B型机车的电气原理,然后通过仿真和线路实测数据对其谐波特性进行了分析,最后通过理论结合实测数据的统计分析,阐述了车网系统谐波谐振特性。这些基础工作对分析该系列车型运用性能和研究高次谐波谐振抑制方案具有一定的参考价值。
Since 2007, with the HXD1 locomotive put into operation as a symbol, the traction power of China’s electrified railway has begun the process of “transmission-direct-transmission to delivery-direct-delivery” transmission transformation. At present, more than 4 500 AC drive electric locomotives have been put into operation. With a large number of AC drive electric locomotives put into use, on the one hand, rail transport efficiency and quality have been greatly improved. On the other hand, it has also brought harmonic resonance problems to the electrified lines, affecting the stability and safe operation of the system. The article elaborates the electrical principle of HXD1B locomotive, and then analyzes the harmonic characteristics of the locomotive through simulation and line measured data. Finally, the harmonic resonance characteristics of the vehicle network system are expounded by theoretical analysis and statistical analysis of measured data. These basic work have certain reference value for analyzing the application performance of this series of vehicles and studying the harmonic resonance suppression scheme.
