摘要
近年来CRH系列动车组大量投入高速铁路,其功率因数、谐波含量等方面的电气特性与传统交—直型机车有较大区别。简要分析了CRH380AL动车组的电气原理,根据实测数据,并利用曲线拟合的方法,主要对该车型功率因数和网侧电流谐波含量进行分析。这些基础工作对分析该系列车型运用性能及牵引供电系统电能质量具有一定的参考价值。
In recent years,the CRH series EMU are launched into high-speed railway lines. The power factor and the current harmonic contents of the CRH series EMU are different from the traditional AC-DC type electric locomotives. This paper briefly analyzes the electrical principle of CRH380AL EMU. On the basis of measured data, the power factor and the current harmonic contents of CRH380AL EMU are analyzed by using curve-fitting method. This basic work is believed to have a certain reference value on analyzing the operation performance of CRH series of EMU and the power quality problem of traction power supply systems.
