Abstract :
This paper presents a frequency estimation methodology in a single-phase voltage signal using adaptative notch filters. The simulations are realized using the Simulink toolbox of MatLab 7.0.4 and executed on a DSP TMS320F2808 platform of Texas instruments. We observe the behavior of PLL in presence of frequency values changes, voltage sags and THD increases. The difference between the frequency calculated and the theoretical system frequency is evaluated. In addition, the algorithm time response used for signal frequency calculation is evaluated.
