Series Resonance Analysis Based on Branch-Circuit Method

    摘要
  • 摘要: 为有效分析电力系统串联谐振引起的支路谐波过电流问题,提出了基于支路法的串联谐振分析方法,应用该方法对三母线系统和IEEE14节点系统进行了测试分析,并与成熟的模态分析法,即通过求解网络导纳奇异矩阵特征根分析谐振机理的方法进行了比较. 利用串联支路出现导纳极大值获得的谐振频率与利用模态分析法得到的谐振频率相近这一结果表明,提出的方法能准确地识别电力系统中的串联谐振频率,有效分析串联谐振问题,具有较好的实用性.

     

    Abstract: A frequency spectrum analysis technology based on the branch-circuit method was proposed to effectively analyze the branch harmonic over-current caused by series resonance in power systems. The proposed method was tested on the three-bus and IEEE 14-node systems and compared with the modal analysis method, which analyzes the resonance mechanism by utilizing the eigenvalue of the singular admittance matrix. The series frequencies determined by the peak admittance obtained by the branch-circuit method are be close to the resonance frequencies obtained by the modal analysis, showing the effect of the proposed method in analyzing series resonance.
