摘　　要：寻找合适的算法是微机保护的一个重要任务,而傅氏算法是目前最广泛采用的一种算法。为此,对两种改进的傅氏算法进行了分析比较,同时使用MATLAB6.1编制算法程序,通过大量的仿真计算,对两种算法的计算精度进行了对比,可为在不同场合下寻找满足特定性能要求的算法提供指导。To seek an appropriate algorithm is an important task for microprocessor-based protective relaying. At present, the Fourier algorithm is widely used. This paper compares the improved full-wave Fourier algorithm with the improved halfwave Fourier algorithm. The algorithms are programmed with MATLAB6. 1, and then the simulation calculations are performed to compare the accuracy of the two algorithms, so as to provide reference for choosing algorithm under different conditions.
