| 摘 要： | Measurement of harmonic parameters, including frequency, magnitude and phase, is a key step in of analyzing and solving of harmonic problems. In electrical power system, the Fast Fourier Transform (FFT) has been widely used in harmonic analysis. Due to the requirement for real time implementation and/or the random shift of signal period, a sampling sequence usually contains only several cycles of the signal and the windowingtime width generally does not strictly equal to multiples of signal …
