摘要
Abstract
Tell about the principle of fourier algorithm for microprocessor based protection and its advantages or disadvantages,put forward the improved Fourier algorithm improved based on difference Fourier filtering algorithm,through the software matlab programming and simulation,get results and comparative analysis of the simulation results,proved that the improved algorithm in filtering on decaying direct current component of validity and availability,greatly improved in power system of fault signal microcomputer protection,thus make the judgment of quickly and accurately action,protect the power equipment,prevent accidents.关键词
