Abstract :
Islanding detection and anti-islanding protection are the essential functions of the gird-connected inverter in DG systems. This paper focuses on the non-detection zone (NDZ) with passive islanding detection method for the DG system with the current control scheme. The parameters of the point of common coupling such as the voltage amplitude and frequency are studied through mathematical derivation. The NDZ regions of the passive islanding detection methods such as OVP/UVP, OFP/UFP are drawn base on the mathematical derivation. And the analysis is verified by the experiment results upon a fuel cell powered DG system with the current control scheme.
