| 摘 要： | 电力机车功率变化直接影响牵引负荷谐波特性,高速动车组与目前广泛应用的交-直机车的谐波特性有明显区别。基于电压型PWM变流器谐波的产生原理和牵引供电系统等效电路,以CRH2动车组为原型构建了交-直-交机车的谐波数学模型。在此基础上对高速机车在牵引和再生制动两种工作状态下功率变化时的谐波电压、谐波电流进行了仿真计算,分析其随功率的变化趋势、动态特性和频谱特性,与实测数据的对比验证了谐波模型及其理论分析的正确性与可行性。

| Abstract: | The harmonics characteristic of traction load is directly affected by variation of locomotive power,and the harmonics characteristic of high speed AC-DC-AC locomotive is different from the one of AC/DC locomotive.On the basis of analyzing harmonic voltage generation process and the equivalent circuit of traction system,a study for the harmonic model current injected was proposed by a typical EMU-CRH2.Harmonic voltage and current under locomotive traction and regeneration braking were simulated.Then the frequency spectrum characteristics and dynamic characteristics of harmonic voltage and current versus locomotive power level were analyzed.The measured results agree well with those by simulation analysis,which indicates the correctness and feasibility of the harmonic model and the theoretical analysis. |
