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,...
Wind power plant is source of harmonics and inter-harmonics. Estimation of these harmonics is very important and crucial task in modern distribution generation environment. This paper presents sliding window matrix pencil algorithm to estimate harmonics and inter harmonics produced by doubly fed induction generator based wind power plant. The series of simulation results under variable wind speed...
Detection of harmonics and inter-harmonics produced by wind power plant is very challenging task for the modern power system researchers. This paper presents estimation of harmonics produced by wind generator under variable wind speed by sliding window ESPRIT and sliding window Root-MUSIC algorithm. The series of simulation results demonstrate advantages of the sliding window ESPRIT over the sliding...
