基于修正模态法的支路串联谐振识别
|
摘要
针对电力系统支路串联谐振识别难的问题,提出了修正节点导纳矩阵模态法的支路串联谐振识别方法。首先,在使用网络矩阵模态法识别节点并联和回路串联谐振点时,发现其对应谐振点重合;经理论分析发现,支路阻抗比越小,对应的回路串联和节点并联谐振点重合度越高。然后,对于支路串联谐振,通过使用添加虚拟支路的方法将其转化为回路串联谐振,并利用系统串并联谐振重合的理论,进一步转化为并联谐振识别。最后,通过对三节点系统和IEEE14节点系统的仿真分析,验证了该谐振识别的可行性和正确性。
For the identification of series resonance in power system branches, the identification method of branch series resonance based on modified nodal admittance matrix modal method is proposed. First of all, when the network matrix modal method is used to identify the parallel connection of the nodes and the series resonance points of the loop, the corresponding resonant points are found to coincide. The theoretical analysis shows that the smaller the branch impedance ratio, the higher the coincidence degree of the corresponding series and parallel resonant points. Then, for branch series resonance, it is transformed into loop series resonance by adding virtual branch, and further transformed into parallel resonance identification by using the theory of system series-parallel resonance coincidence. Finally, the feasibility and correctness of the three node system and the IEEE14 node system are verified by simulation analysis.
