| Abstract: | 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. |
