摘　　要：傅氏算法强大的滤波效果使它在电力系统中得到了广泛的应用,尤其是在微机的保护方面。对当今比较流行的几种傅氏及其改进型算法进行了比较分析;并使用Matlab建立了电力仿真模型,模拟出了故障状态。采用性能较好的3种算法,对故障信号进行了滤波处理,以验证它们的实际应用价值。The Fourier algorithm makes a widely used in power system because of powerful effect of filter, especially in microprocessor-based protection. The comparison and evaluation of improved Fourier algorithms was presented. A model of the power system by Matlab was built, and the result of simulation of power system fault with improved Fourier algorithm was analyzed.
