【摘要】：電網(wǎng)中的諧波危害十分嚴(yán)重,隨著網(wǎng)絡(luò)結(jié)構(gòu)日趨復(fù)雜化,因諧振造成的諧波污染問題變得更加突出。為了更好地研究分析電網(wǎng)諧振規(guī)律,提出一種基于奇異值分解理論的諧波放大分析方法。該方法通過提取諧波源與響應(yīng)之間傳遞函數(shù)矩陣中的關(guān)鍵信息,獲取網(wǎng)絡(luò)中節(jié)點(diǎn)電壓和支路電流的諧波放大規(guī)律。理論分析和算例分析結(jié)果驗(yàn)證了所提出的諧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.
