摘要
通过对SS3B型电力机车电路模型的分析 ,阐述了机车相控整流谐波产生的机理。运用离散傅立叶算法和电力电子技术 ,对机车理论负荷电流的谐波进行了分析计算。借助牵引变电所负荷录波装置 ,对实际馈线电流电压波形进行频谱分析。得出机车在几种运行状态下的负荷特征 ,验证了理论与实际负荷分析的一致性。
Based on the analysis of circuit model of SS 3B electric locomotive, the paper expatiates the reason of rectifier harmonic. Applying DFT arithmetic and power electronical technique to harmonic analyses the loading-current in theory. With the assist of waveform recorded in substation to sample the data, proceed to form the actual current and voltage frequency spectrum. In the end achieve the loading characteristic in some types of state, and conclude the loading analysis in theory and in practice is consistency.
