用hanning窗的插值FFT算法，适用于电力系统信号的谐波分析,Hanning window with interpolation FFT algorithm, applied to power system harmonic analysis signals

基于快速傅里叶变换的谐波叠加法风速时程模拟，虽然是已有算法，但是经过自己切实操作保证可用，并且加入频谱比较以及结果输出-Fast Fourier Transform harmony superposition method simulation process when wind speed, although the existing algorithms, but through their own operations to ensure the effective available,
