摘要(Abstract)：

通过计算与分析,论证了系统并联谐振频率与回路串联谐振频率完全相同。比较几种不同的模态分析法并得出结论:基于节点导纳矩阵或基于节点阻抗矩阵的模态分析法适用于系统并联谐振分析,且两种方法结果相同;基于回路阻抗矩阵的模态分析法适用于回路串联谐振分析,由于系统回路串联谐振频率与并联谐振频率完全相同,因而与系统并联谐振分析结果相同,单一使用基于回路阻抗矩阵的模态分析法并不能求得支路串联谐振频率;结合运用基于节点导纳矩阵的模态分析法和虚拟支路法,可求得包括支路串联谐振频率在内的系统全部谐波谐振频率。论证了虚拟支路法对于支路串联谐振分析的适用性。
Through calculation and analysis, the paper demonstrates that the parallel resonance frequency of the system is the same as the loop series resonance frequency. It is concluded by comparing several different modal analysis methods that modal analysis methods based on node admittance matrix or node impedance matrix are suitable for the analysis of parallel resonance, and the results of the two methods are the same. The modal analysis methods based on loop impedance matrix are suitable for the analysis of loop series resonance. Because parallel resonance frequency of the system is the same as loop series resonance frequency of the system, the results of harmonic resonance are the same as the analysis of parallel resonance. The modal analysis method using loop impedance matrix only can not conclude branch series resonance frequency. In combination with modal analysis method and virtual branch based on node admittance matrix, all harmonic resonance frequencies including branch series resonance frequency can be concluded. The paper demonstrates that the virtue branch method can be applicable to tributary series resonance analysis.
