摘要
探讨了傅氏算法在电力系统继电保护中的应用。介绍了傅氏算法的基本原理和两种典型算法——全波傅氏算法和半波傅氏算法。阐述了它们在继电保护中发挥的重要作用,并对两种算法进行仿真和性能比较,仿真结果表明,傅氏滤波算法在继电保护中具有实用性。
Discussion was made on Fourier algorithm application in power system relay protection. Introduction was made to the basic principle of Fourier algorithm and two kinds of typical algorithms-whole-wave Fourier algorithm and half-wave Fourier algorithm. Description was made on their important roles played in relay protection, also simulation and performance comparison were carried out for the two algorithms. The simulation result shows that Fourier wave filtering algorithm is with practical use performance in relay protection.
