摘要
利用PSCAD仿真软件对韶山Ⅳ型电力机车(SS4)的运动过程建立动态仿真模型,提出了基于傅里叶级数展开方法的谐波电流计算方法。并以AT牵引变电所为算例,带入机车模型进行仿真计算,得出各次谐波电流分量及其谐波含量,并与实测数据进行了比较,结果证明本方法及模型是有效的。
This paper presents constructs a dynamic simulate model of type-SS4 electric locomotive＇s movement by using simulation software PSCAD,and proposes a method based on fourier series expansion to calculate harmonic currents.Also,AT traction substation for example,drag-in SS4 locomotive simulation model to calculate,then educe the harmonic currents and their content.Compare with measured data,results show that this method and model are effective.
