Abstract

This paper proposes a new active islanding protection method for use in a small-scale, grid-interconnected distributed synchronous generator (DSG) system. The proposed correlation factor method is based on voltage fluctuation injection, which can be obtained through the high impedance load switching on the grid periodically. The correlation factor between the periodic switching signal and the perturbed voltage is then used as an islanding detection index. Experimental results demonstrate the principles of the proposed technique and show the new proposed method is reliable, economical, and easy for implementation.
