Abstract—This paper presents an anti-islanding protection scheme for a grid tied inverter. In this scheme, the oscillation variation in frequency is estimated by Estimation of Signal Parameters via Rotational Invariant Technique (ESPRIT). The proposed system is implemented in MATLAB and real time in OPAL-RT. Series of simulation results demonstrate that nondetection zone of proposed algorithm is negligible, and the scheme is also free from nuisance tripping to other transient events.
