A Novel Grid Synchronization Method Based on Hybrid Filter Under Distorted Voltage Conditions

A Novel Grid Synchronization Method Based on Hybrid Filter Under Distorted Voltage Conditions

The phase-locked accuracy of conventional phase-locked method is reduced when the grid voltage contains fundamental frequency negative sequence(FFNS) component, harmonic component, and DC offset component. Aiming at this problem, a novel adaptive notch filter (NANF) is proposed, and a dual NANF (DNA...
