【摘要】：电网中的谐波危害十分严重,随着网络结构日趋复杂化,因谐振造成的谐波污染问题变得更加突出。为了更好地研究分析电网谐振规律,提出一种基于奇异值分解理论的谐波放大分析方法。该方法通过提取谐波源与响应之间传递函数矩阵中的关键信息,获取网络中节点电压和支路电流的谐波放大规律。理论分析和算例分析结果验证了所提出的谐波放大分析方法的有效性。
[Abstract]:The harmonic damage in power network is very serious. With the network structure becoming more and more complicated, the harmonic pollution caused by resonance becomes more prominent. A harmonic amplification analysis method based on singular value decomposition (SVD) theory is proposed in order to better study and analyze the resonance law of power grid. By extracting the key information from the transfer function matrix between the harmonic source and the response, the harmonic amplification law of node voltage and branch current in the network is obtained. The results of theoretical analysis and numerical analysis verify the effectiveness of the proposed harmonic amplification analysis method.
