| 摘 要： | 利用数学公式分析电力机车励磁涌流大小,基于MATLAB/SIMULINK搭建电力机车牵引主变压器模型,分析得出合闸时间、剩磁、变压器容量和接触网电压幅值是影响励磁涌流大小的因素。建立车载主变压器、接触网和牵引变压器的仿真系统,选取电压波动作为评估励磁涌流对电力系统公共连接点影响的参数。分析电力机车发生励磁涌流时,不同牵引变压器接线形式下公共连接点电压波动的大小,并得出励磁涌流对公共连接点存在影响但不明显的结论。

| Abstract: | At present, research on inrush current in the field of electric locomotive is in situation of less study. This paper uses the math formula of inrush current to analyze the magnitude, sets up main transformer model of electric locomotive based on MATLAB/SIMULINK, and the factors which have influence on the inrush current are discussed. The switching time, the residual flux, the transformer capacity and the voltage magnitude of the traction line are all the dominant factors. The simulation system which consis... |
