摘要
电力机车是电力系统中的主要谐波源之一。本文介绍了６Ｋ型电力机车的电路特征，分析了机车电流的变化规律，并给出了谐波电流的计算方法。
Electrirled locomotive is one of the main harmonic source in the electric power system. In this paper, the circuit character of type 6K electrified locomotive is introduced,the change aaw of locomotive current is analysed and the calculation method of harmonic current is given.
