With the widely application of a great quantity of nonlinear electrical components, harmonie and interharmonic components in power system have become a complicated problem. In the power system, there is fundamental wave, harmonics and interharmonics. The Fast Fourier Transform method can make the precise detection and analysis of integer harmonies come true, which based on simple transformation of FFT. In order to accurate detect interharmonics people must eliminate the interference between harmonie and fundamental. Their characteristic help us to distinguish them. In order to improve computing speed, three point method combine FFT Because of these improvement ,people can calculate interharmonics accuracy.
