中文摘要 | 本文應用小波輔助法觀測電力系統諧波趨勢。由於小波理論兼具時間及頻率之局 部觀測能力,因此可將其應用於電力品質課題上諧波趨勢之監督。文中將所提之方法應用於 電弧爐及馬達啟動運轉上之諧波動態觀測,執行結果證實此方法在該類相關應用上具有其優 點及實用性。 |
英文摘要 | A wavelet-aided approach to visualizing power system harmonic trends is proposed in this paper. With time-frequency localization characteristics embedded in wavelets, the time and frequency information of a waveform can be presented as a visualized scheme. Different from the fast Fourier transform, the proposed method is more efficient in monitoring harmonic dynamics. The proposed method has been tested on an arc furnace and electric drives Test results demonstrate the practicality and advantages of the method. |
