HX_D1B型机车谐波特性分析

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。

Analysis of harmonic characteristics of type HXDIB locomotive

Since type HXD1 locomotive is launched into operation in 2007, the traction of China railway electrification began ＂AC-DC＂ drive to ＂AC-DC-AC＂ drive transformation process. At present, more than 4 500 AC drive electric locomotive have been launched into operation. A large number of AC drive electric locomotive is in operation. While greatly enhancing the efficiency and quality of rail transport, it also brings to the electrified line harmonic resonance issue that affects the stability and security of system operation. This paper expounds the electrical principles of type HXD1B locomotive, analyzes its harmonic characteristics by simulation and test data. Finally by combining theoretical analysis with statistical analysis of test data, it elaborates locomotive-line system harmonic resonance characteristics. This basic work is believed to have a certain reference value on analyzing the operation performance of HXD series electric locomotives and research the solutions of high-order harmonic resonance suppression.
