wpd 中文意思是什麼
wpd
解釋
WPD ＝ War Plans Division 〈美俚〉作戰計劃處。-
Based on wavelet packet decomposition （ wpd ）, entropy threshold method （ etm ） has been put forward to reject the discrete spectrum interference （ dsi ） in on - line pd monitoring
首次提出用於抑制局部放電在線監測中周期性窄帶干擾的小波包變換熵閾值法（ etm ） 。 -
With the frequency division of wpd, etm uses shannon entropy as the criterion of determining whether or not dsi exist in certain wpd tree nodes and interference are suppressed successfully. lots of simulation data, lab data and on - site data have indicated that etm works with good efficiency, without pre - knowing of dsi information, extracts the phase of pd pulses accurately and can calibrate quantity of single type discharge
大量的模擬數據、實驗室實測數據以及現場實測數據處理結果表明，小波包變換熵閾值法抑制干擾能力強，無需事先確定干擾的分佈，能夠準確檢測局部放電信號的相位信息，對于單一的放電類型，可以確定放電量的大小。
