Abstract
It is important that PV systems detect islanding caused by power system fault to ensure electrical safety. So, we propose a novel islanding detection method which detects harmonic impedance by injecting the harmonic currents synchronized with exciting current harmonics of the pole transformer. In case that an induction motor load is included in the load system, the basic experiments of islanding detection and simulation analysis are conducted to verify the effectiveness of the proposed method.
