摘　　要：介绍了近年来微机保护应用中针对傅氏算法的各种改进算法 ,着重研究分析了如何滤除衰减直流分量问题 ,并通过仿真计算 ,对各种算法的滤波性能 ,即复现基波分量和各次谐波分量的速度和精度 。This paper presents all sorts of improved methods based on Fourier algorithm, which are used in microprocessor based protection in recent years, and particularly discusses the problem of how to filter decaying DC component. With the results of simulating calculation, the comparison and evaluation of the abilities, i.e. speed and precision, of these algorithms is also presented.
