摘要
寻找合适的算法是微机保护的一个重要任务。分析了傅里叶算法的基本原理,通过对历史文献的综合分析,首先给出了微机保护常用算法中的傅里叶算法,在此基础上给出了几种改进后的傅里叶算法。通过了大量的仿真计算证明不但切实可行,而且能够有效地滤除衰减非周期分量的影响。具有较高的理论和实用价值。
To seek an appropriate algorithm is an important task for microcomputer relay.The basic principle of the Fourier algorithm and the previous documents are analyzed in this paper, firstly the Fourier algorithm for conventional algorithm in the microcomputer relay and the improved Fourier algorithm based on the former are presented.A lot of simulations (are carried out) prove that the new algorithms have strong filtering capability for exponential decaying aperiodic component.All of the above show that the methods presented in this paper are full of values in theory and practice.
