Interharmonic is special harmonic in electric power systems.
间谐波是电力系统中一种特殊的谐波。
The concept of "interharmonic record" is presented to measure the interharmonic content of power grid.
提出了“间谐波记录”这一概念，有利于衡量电力系统中间谐波的含量。
The simulating result shows that the algorithm improves spectral estimation performance obviously, and can get better interharmonic spectral estimation with less datas.
仿真结果表明，该算法明显改善了谱估计的性能，而且只要用比较短的数据即可得出较好的间谐波谱估计。
The fast Fourier transform (FFT) will bring on higher error under nonsynchronous sampling and truncated non-integral period, thus more accurate interharmonic parameter values cannot be obtained.
快速傅里叶变换在非同步采样和非整数周期截断的情况下存在较大误差，无法获得较精确的间谐波参数值。
