This paper proposes a robust, fast and accurate estimation technique for the tracking of time-varying grid voltage parameters. The proposed technique consists of a fundamental frequency tracking method based on a fixed window discrete Fourier transform (DFT) and a quadrature signal generator (QSG) based on a second order generalized integrator (SOGI) in… CONTINUE READING
