摘要
数字滤波算法的性能直接影响着距离保护的操作效果。提出了基于最大重复小波变换的阻抗继电器新滤波算法,它可用于微机继电保护装置中;仿真结果表明,该算法的计算精度和收敛速度较传统算法有很大提高。
The effectiveness of the relay-protection is significant influenced by the performance of digital filter in transmission line distance protection . A new filter algorithm for impedance relay viamaximal overlap discrete wavelet transform (MODWT) is presented in this paper, which can used in microprocessor-based protection relays ; The simulation results are presented the high precision and rapid velocity of convergence of the new algorithm.
