| Abstract: | Based on the supply characteristics of aviation ground power,we studyed the advantages and disadvantages of the radix-2 algorithm,radix-4 algorithm,and split-based algorithm and introduced radix-2 FFT algorithm for harmonic detection.Simulation based on a least square method used for harmonic parameters estimation shows that the method can effectively improve the detection accuracy. |
