| 摘 要： | 在非同步采样下，采用快速傅里叶变换（fast Fourier transform，FFT）进行电力谐波分析容易造成频谱泄露和栅栏效应。窗函数加权可有效抑制频谱泄漏，但经典窗函数的抑制能力受旁瓣性能的制约。分析了纳托尔（Nuttall）窗的频谱特性后，提出了一种通过若干Nuttall窗自卷积运算得到的新型窗函数——．Nu...

| Abstract: | The signal spectral leakage and fence effect are prone to take place during the power harmonic analysis by fast Fourier transform(FFT) under non-synchronous sampling.Although the signal spectral leakage can be effectively inhibited by weighted window function,however the inhibiting ability of classical window function is restricted by the behavior of sidelobe.Based on the analysis on spectrum characteristic of Nuttall window,a new type of window function,namely the Nuttall self-convolution window,is obtaine... |
