| 摘 要： | 针对电网负载电流的低信噪比问题,提出一种用于有源电力滤波器(APF)谐波检测的多重因子变步长自适应谐波检测方法.该方法以自适应噪声对消技术为基础,通过引入动态因子,增加相邻时刻误差信号的自相关值及静态因子对权值迭代的影响,并利用误差信号的时间均值估计来控制步长更新,不但加快了动态响应速度,而且减小了低信噪比情况下的稳态...

| Abstract: | To solve the problem about the low signal to noise ratio of load current,a multiple factor variable step adaptive harmonic detection algorithm is proposed for active power filter(APF).Utilizing the adaptive noise cancella-tion technology,the algorithm is introduced to update the step size based on the estimation of the time average of er-ror signal.By introducing the dynamic factor,increasing the error signal from the adjacent time-related values and stat-ic factors on the impact of weight iterations,and us... |
