Improved Three-Phase AFD Islanding Detection Based on Digital Control and Non-Detection Zone Elimination

This paper proposes an improved active frequency drift (AFD) islanding detection method of a three-phase inverter. Different than the existing single-phase AFD method, in the three-phase system, the disturbance is added to the phase angle, which takes part in coordinate transformation calculations....
