摘要

离散傅里叶变换(DFT)和快速傅里叶变换(FFT)是基于一定的假设，必须理解和满足，否则会得到误导的结果。本文对这些假设进行了检验，并定性地分析了将FFT算法用于电力系统负荷变化时这些危险的影响。他们建议使用DFT算法来评估电力系统负荷变化的频谱。

Application of DFT and FFT algorithms to spectral analysis of power system load variation

The discrete Fourier transform (DFT) and the fast Fourier transform (FFT) are based on certain assumptions that must be understood and satisfied, or misleading results will be obtained. The authors examine these assumptions and qualitatively analyze the effect of these dangers when the FFT algorithm is supplied to power system load variation. They recommend the use of a DFT algorithm to evaluate the frequency spectrum of power system load variation.<>
