ESPRIT based robust anti-islanding algorithm for grid-tied inverter
2016 IEEE Students' Technology Symposium (TechSym), 2016•ieeexplore.ieee.org
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 non-detection zone of proposed algorithm is negligible, and the scheme is also free
from nuisance tripping to other transient events.
