电气化铁路接触网上谐波的分布

Harmonic Wave Distribution along the Traction Network of Electrified Railway

本文将电力机车等效成电流源,建立接触同系统的等效电路,分析了由电力机车在电气化铁路接触网上产生的高次电压和电流谐波的分布形式.

By means of the equivalent circuit of electrical locomotive and traction network, author studied the voltage and current harmonic wave distribution along traction network of electrical railway.Formulas for the calculation of current and voltage were given.Finally author discussed the results obtained by these formulas under some special conditions.
