A new virtual calibrator for instrument transformer is presented . a phase difference correction method is applicable to correct electronic instrument transformer 摘要介紹了一種新型的虛擬互感器校驗儀,它采用相位差校正法解決了校驗電子式互感器的問題。
After analysising three existed methods for phase difference correction on discrete spectrum , it is recommended to correct the spectrum containing small noise in engineer practice by the first phase difference correcting method ( performing fft analysis on two continuous original sequence ) with harming window 綜合分析現(xiàn)有三種離散頻譜相位差校正方法,推薦在小噪聲工程實際中加hanning窗的第一種相位差法(采連續(xù)兩段信號作相同點數(shù)fft的相位差校正法)進(jìn)行校正。
Study shows that the basic principles of three existed methods for phase difference correction on discrete spectrum are identical , by which the twice fft analysis through time - domain shifting time series or changing window ' s length is performed , and the spectrum by making use of the phase difference of two corresponding peak lines are finally corrected 在研究時域平移的離散頻譜相位差校正方法和改變窗長離散頻譜相位差校正方法的基礎(chǔ)上,發(fā)現(xiàn)這幾種離散頻譜相位差校正法的基本原理是一致的,就是通過時移和加不同的對稱窗進(jìn)行兩次fft分析,并利用離散頻譜對應(yīng)峰值譜線的相位差以求得頻率和相位校正量。
