利用Blackman窗函数对工频信号进行加窗FFT后校正计算出基波和谐波的幅值、频率和初始相角。-Blackman window function using frequency signal windowed FFT is calculated after the correction of fundamental and harmonic amplitude, frequency and initial phase angle.

生成电能质量模拟数据的函数，包括基波，谐波，震荡，电压波动，尖峰等信号的模拟,运行run为示例程序-A function generate power quality signal for analysis. Including harmonic shock voltage changing and so on. File run.m is a demo
