| 摘要: |
| 基于谐波谐振模态分析(HRMA)法及谐波谐振严重程度的相关概念介绍，通过数学原理分析指出HRMA法在谐振严重程度分析上的不足，并采用归一化电压法实证了HRMA法存在偏差不可忽略的情形。定义谐振严重程度换序矩阵、谐振严重程度偏差矩阵和分段偏差平均值指标，以准确描述谐波电流从不同节点注入时HRMA法中关键左特征向量在反映谐振严重程度方面存在的偏差，进而改进了谐振严重程度的分析流程，得出应在精准度不足时结合系统矩阵分析谐振严重程度，并根据具体问题的目标需求生成对应的补充集以实现对HRMA法偏差修正的结论。基于IEEE 30节点系统应用所提方法对HRMA法进行精度分析，并以谐振监测点选择问题为例采用生成补充集的方式实现对HRMA法偏差的修正。 |

| Abstract: |
| Based on the introduction of harmonic resonance mode analysis(HRMA) method and related concepts of harmonic resonance severity, the deficiencies of HRMA method in the analysis of resonance severity are pointed out through mathematical principle analysis, and the normalized voltage method is used to prove that the deviation of HRMA method cannot be ignored. The resonance severity sequential swapping matrix, the resonance severity accurate deviation matrix and the average segmented deviation index are defined to accurately describe the deviation of the key left eigenvector in HRMA method in reflecting the resonance severity when the harmonic current is injected from different nodes, and then the analysis process of resonance severity is improved. It is concluded that when the accuracy is insufficient, the resonance severity should be analyzed in conjunction with the system matrix, and the corresponding supplementary set should be generated according to the target requirements of the specific problem to achieve the deviation correction of HRMA method. The accuracy of HRMA method is analyzed based on the proposed method in the IEEE 30-bus system, and the resonance monitoring point selection problem is taken as an example to correct the deviation of HRMA method by generating a supplementary set. |
