Optimization design of DC 600 V train power supply device for HX_(D)1G locomotive

现有HX_(D)1G型机车DC 600 V列车供电装置电路拓扑结构的输出电流波动大,会对后端的客车负载造成一定的影响,为此文章介绍了HX_(D)1G型机车DC 600 V列车供电装置的电路结构,并对其谐波电流的形成原因进行了分析,提出在列车供电装置输出端增加直流滤波电感的优化方案。经试验验证,该方案优化后的列车供电装置可满足机车供电需求。

The output current of circuit topology of DC 600 V train power supply device for HX_(D)1G locomotive fluctuates greatly,which will have a certain impact on the rear passenger car load.Therefore,this paper presents the circuit structure of DC 600 V train power supply device for HX_(D)1G locomotive,and analyzes the causes of its harmonic current.The optimization scheme of increasing the DC filter inductance at the output end of train power supply device is proposed.The test results show that the optimized train supply device can meet the power supply demand of locomotive.
