摘要:
 针对在采用快速傅里叶变换分析电力谐波时,对信号非同步采样以及非整周期截断的 情况下,会产生频谱泄露和栅栏效应,无法有效检测谐波的各参数值等问题,提出了加窗插值算法, 能够提高计算精度抑制频谱泄露,Kaiser 窗的频带内能量主要集中在主瓣中,拥有绝佳的旁瓣抑制 性能,该算法充分利用峰值谱线频点最近的四条谱线进行加权运算提高运算精度,运用 MATLAB 多项式拟合推导出实用的插值修正公式。仿真结果表明,四谱线插值算法得到的21 次谐波的幅值 相对误差≤0. 000 01%,相位相对误差≤0. 000 001%,基波频率计算相对误差为6. 2 × 10 -11%,并 且能够有效消除频谱泄露和栅栏效应的影响,计算精度更高。
Abstract:
 When the Fast Fourier Transform ( FFT) method is used to analyze the harmonics in a power network,the fast Fourier transform ( FFT) can produce spectral leakage and fence effect under the situation of nonsynchronized sampling and non-integral period truncation,which leads to a great error in the results of calculation. The window functions and interpolation algorithm can reduce spectral leakage and improve the accuracy of computation. By MATLAB data fitting,practical correction formulas corresponding to commonly used window functions are obtained by using weighted arithmetic of four pillars spectral line near the harmonic frequency point. The simulation and test results show that the relative errors of amplitude for 21 order harmonics are no more than 0. 00001%,the relative errors of phrase collection for 21 order harmonics are no more than 0. 000001%,and the relative errors of fundamental wave frequency are 6. 2 × 10 -11% . The algorithm can eliminate the influence of spectral leakage and fence effect effectively,improving the accuracy of harmonic analysis
