IEC协会推荐的电压波动和闪变的测量计算方法，并含相关的IEC标准和国标（这些标准很难找到免费的）(IEC Association recommended voltage fluctuation and flicker measurement and calculation methods, and with the relevant IEC standard and GB (hard to find these standards for free))

线性卷积要求两个输人序列具有持续时间，但在实际应用中，可能遇到输人序列具有无限持续时间的情况。在这种情况下，分段卷积是一种有效的解决方案。文章讨论了计算分段卷积的两种方法。仿真试验表明，分段卷积方法正确且高效。(The linear convolution needs two finite-time input sequences, but in the actual application, two infi- nite-time input sequences are possible. Under this kind of situation, the partition convolution is an effective solu- tion. In this paper, two methods of the partition convolution are discussed. The simulation experiment indicatesthat the partition convolution is correct and effective.)
