Abstract
In this paper, a novel anti-islanding method of DC-AC single phase inverter is proposed. The inverter injects a little harmonic current with the output current of a PCS(Power Conditioning System). When the islanding condition is occurred, the voltage harmonic components appear on the output voltage of the PCS due to the injection of a little harmonic current. So, the PCS detects the voltage harmonic components using the Goertzel algorithm, and then the PCS decides that the islanding condition is occurred. When the PCS recognizes the islanding condition, the PCS are stopped. The proposed a novel anti-islanding method is analyzed, and its validity is proven through simulation.
