电气化铁路不停电过分相系统对机车影响研究
|
摘要
目前国内主流的过分相方式是车载自动过分相方式,列车要断电通过长达数千米的中性段,速度损失严重。不停电过分相方式则能有效解决速度损失问题。以地面不停电过分相方式为基础,将整个车网模型进行简化,分析在地面不停电过分相方式对电力机车的影响。并在PSCAD/EMTDC软件中搭建车网仿真模型以及地面自动过分相装置的简化模型,利用此模型探究采用地面自动过分相技术对电力机车四象限整流器以及车端电压的影响。
At present,the mainstream over-phase method in China is the automatic over-phase method of the vehicle. The train has to be powered off through the neutral section of several kilometers,and the speed loss is serious. The speed loss problem can be effectively solved without over-discharging. Based on the ground-based non-power-off over-phase method,the entire vehicle network model is simplified,and the influence of the over-phase method on the ground without power-off is analyzed. The vehicle network simulation model and the simplified model of the ground automatic over-phase separation device are built in the PSCAD/EMTDC software. This model is used to explore the influence of the ground automatic over-phase separation technology on the four-quadrant rectifier of electric locomotive and the voltage of the vehicle terminal.
