Frequency Adaptive Discrete Filter for Grid Synchronization Under Distorted Voltages

This paper presents a frequency adaptive discrete-time-domain nonlinear filter for three-phase grid synchronization. Due to the discrete time nature of the proposal, all the analysis performed here is valid for a DSP implementation, and this implementation is straightforward. The proposed algorithm...

Beschreibung
Zusammenfassung:This paper presents a frequency adaptive discrete-time-domain nonlinear filter for three-phase grid synchronization. Due to the discrete time nature of the proposal, all the analysis performed here is valid for a DSP implementation, and this implementation is straightforward. The proposed algorithm has very low computational burden, as in its basic form it only requires three states.
