摘要
本文考虑牵引网的影响，通过建立机车换相等效电路模型，导出了较为完善的谐波计算数学模型．又利用付里叶分解，对机车电而进行了谐波分析．结合豁山７型电力机车的具体参数，对在不同运行工况下的机车谐波特性进行了模拟计算．
In view of the affection of traction network, by establishing the commutation equivalent circuit model of multi-step bridge, the mathematical model to calculate the harmonic of electric locomotive is given in this paper. And the harmonic analysis of locomotive current is made by Former decomposition. Moreover, locomotive harmonic properties under various operating mode are analogously calculated in the light of the specific parameters of the SS7 electric locomotive.
