摘要
基于对交-直型机车与交-直-交型机车谐波特性的分析,对车网系统之间的耦合作用机理进行了阐述,研究了网侧电压谐波对交-直-交型机车变流器的作用机理,并以单线直供牵引网为例绘制了系统谐波阻抗波形图。建立了高次谐波车网系统仿真模型,利用仿真手段对车网耦合作用机理进行了深入研究和验证。得出的结论对今后研究及治理车网高次谐波耦合现象可起到重要的参考作用。
Based on the analysis of AC-DC and AC-DC-AC locomotive harmonic current character,the network-harmonic coupling effect mechanism was elaborated.The influence of function principle of harmonic voltage on AC-DC-AC locomotive rectifier was investigated,the system harmonic impedance was drawn in the case of single-line NF traction network.The further research was done by utilizing high-order harmonic network-locomotive system model so that the theoretical analysis mentioned before was verified.The result can help play a key role in research and management of high-order harmonic network-locomotive coupling phenomenon in the future.
