root-mean-square voltage 中文意思是什麼
root-mean-square voltage
解釋
電壓有效值-
Then, this thesis concerns with the wavelet transform and its application in power system and compare the deficiency vs strongpoint between the fourier transform, short - time fourier transform. this article point out that wavelet transform fit for non - stationary signals analysis and put it into the measurement of voltage sag. based on the comparion of several algorithm of voltage sag measurement in the literature, the thesis put up a new voltage sag measurement algorithm - - - combination of wavlet transform and root - mean - square. the thesis validate the algorithm according to simulation and actual measuring data
並將小波分析用於電壓凹陷的測量中。在詳細對比了現有文獻上已有的幾種凹陷檢測演算法的基礎上,提出了有效值與小波分析相結合的電壓凹陷測量演算法,文章對小波函數的選取,處理時的去噪,分解尺度的確定等問題進行了詳細的論述,從而實現了本文提出的電壓凹陷定義的測量。根據實測數據和模擬數據,對該演算法進行了驗證,證明該演算法是可行的。 -
