- It deduces the interpolation formula of simultaneous sampling datum calculated by the asimultaneous sampling datum and uses fast fourier transform ( fft ) technology to calculate harmonic parameters . in the end , it gives harmonic errors " datum and curves by means of math model and computer simulation
在此基础上，导出了用非同步采样数据计算同步采样数据的插值公式，并根据复序列快速傅立叶变换（ fft ）原理对插值后的采样数据进行分析和计算，从而得到电网谐波参数。 - The paper analyses the advantages and disadvantages of a large number of harmonic analysis methods and puts forward to a new algorithm in order to improve precision of fft , which is plural list and interpolating windowed split - radix fft ( srfft ) . the simulating result shows that the algorithm can meet precision of harmonic parameters
为了提高fft的精度，本文在分析目前国内外各种谐波分析及测量方法利弊的基础上，提出了利用复序列加窗插值分裂基快速傅立叶变换( srfft ) 。该算法能极大地提高fft计算的精度，从而满足谐波测量中对谐波参数的精度要求。
