| 提出了改进虚拟支路法的串联谐振分析方法。将非理想的谐波电压源等效为等效阻抗和Norton支路的组合，利用由节点导纳矩阵得到的关联矩阵代替回路阻抗矩阵进行串联谐振分析，通过支路法求取支路电流响应获得串联谐振频率及谐振幅度，有效地解决了节点导纳矩阵维数较大问题。利用所提方法对高速铁路牵引网串联谐振进行分析，结果证明了它的准确性和有效性。 |

| Abstract: |
| A method of series resonance analysis based on the improved dummy branch method is proposed， which equals the non-ideal harmonic voltage source with the combination of equivalent impedance and Norton circuit，replaces the loop impedance matrix with the correlation matrix obtained by the node admittance matrix to analyze the series resonance，and applies the branch method to obtain the branch current response for calculating the series resonance frequency and amplitude to effectively avoid the large dimension of the node admittance matrix. The proposed method is used to analyze the series resonance of high-speed railway traction network and the analytical results show its correctness and effectiveness. |
