| 摘要: |
| 高速铁路牵引供电系统不同的负荷模型将得到不同的节点导纳矩阵，从而对谐波谐振幅度、频率产生较大的影响。利用复矩阵模态分析研究不同高速列车的谐波模型对高速铁路牵引供电系统谐波谐振特性的影响规律。将利用频谱分析得到的驱动点阻抗变化曲线与三种不同负荷谐波模型得到的模态幅值和频率敏感度分析进行对比。结果表明，不同的谐波模型在相同的谐振模态下得到了相近的谐振频率区域。 |

| Abstract: |
| Different modal admittance matrix, obtained according to different harmonic model of non-linear loads (NLLs), may have a big influence on the modal impedance and modal frequency in a resonance mode. The effect of load modeling of high-speed train on resonance behavior of high-speed railway traction supply system employing modal sensitivity of modal analysis approach is investigated. Results inferred from the driving point impedance curve got from frequency scan are compared with those of the modal sensitivity analysis with three different NLL models. The results show that different NLL models produce closed resonance frequency zone in the same resonance modes. |
