| 摘 要： | 为了分析电力机车产生的谐波对电力系统的影响,以某牵引变电所普通的Ynd11型变压器接线为例,从动态的过程对牵引供电系统和电力机车进行建模仿真,分析了注入110 kV侧的不平衡谐波电流和电压;通过模型的仿真结果和实际测量数据对比验证了模型的正确性;同时,针对机车不同牵引功率,仿真分析了其对电力系统影响,包括电流谐波、电压谐波和负序电压变化.结果表明:电流、电压谐波随着功率的增加呈曲线增加,其变化趋势复杂;而负序电压含量变化近似一条直线,与功率的变化成正比.

| Abstract: | In order to analyze the influence of harmonic caused by electric locomotive on power system,taking Ynd11 transformer connection of a traction station as an example,this paper presents a dynamic model of electric locomotive and traction power supply system,and then presents simulation analysis of the imbalance harmonic current and voltage injecting 110 kV side.Comparison of the simulation results with the actual measurement data at a traction station verifies the correctness of the proposed model.Finally,the... |
