Abstract :
In this paper, a variable-step ANF for estimation of power quality frequency is presented. This algorithm is fast and accurate. It still get a satisfied result under a high sampling rate. The algorithm of adaptive IIR notch filter with variable-step is presented in detail, and some variable-step method is presented. At last, the simulation is performed by Matlab and the result is compared under different SNR.
