电力系统微机保护算法综合性能研究

Synthetic performance comparison of algorithms for microprocessor-based protections

首先,介绍了基于不同交流采样模型的微机保护算法,主要有基于纯正弦模型算法、基于周期函数模型算法及基于随机函数模型算法。对各个算法的原理进行了概述和分析,同时对各种算法的滤波性能作了综合比较。重点分析了傅氏算法及其改进算法。最后,对傅氏算法和卡尔曼滤波算法进行了比较。

Algorithms for microprocessor-based protections based on different AC sampling models are introduced , including pure sine model, cyclic function model and random function model. The principle of each algorithm is introduced and analyzed. Their filtering performances are synthetically compared. The Fourier algorithm and its improved algorithm are emphasized. Comparison is specially performed between Fourier algorithm and Kalman algorithm.
