A family of gradient descent grid frequency estimators for the SOGI filter
Matas Alcalá, José; Martín Cañadas, María Elena; Hoz Casas, Jordi de la; Abusorrah, A.; Al-Turki, Y.A.; Al-Hindawi, M. (2017-09-04)
Article
Restricted access - publisher's policyThis paper applies the adaptive gradient descent method to the second-order generalized integrator (SOGI) filter in order to find an online estimation algorithm for the grid frequency, which leads to the proposal of three ... -
A new LPF-based grid frequency estimation for the SOGI filter with improved harmonic rejection
Matas Alcalá, José; Martín Cañadas, María Elena; El Mariachet Carreño, Jordi; Abusorrah, A.; Al-Turki, Y.A. (2018)
Conference lecture
Open AccessThis paper proposes a new method for the estimation of the grid voltage frequency using a low-pass filter (LPF) approach. The estimated frequency is used to tune a second order generalized integrator (SOGI) filter commonly ... -
A new THD measurement method with small computational burden using a SOGI-FLL grid monitoring system
Matas Alcalá, José; Martín Cañadas, María Elena; Hoz Casas, Jordi de la; Abusorrah, A.; Al-Turki, Y.A.; Alshaeikh, Hamed (Institute of Electrical and Electronics Engineers (IEEE), 2020-06-01)
Article
Restricted access - publisher's policyThis article proposes a new method for obtaining the total harmonic distortion (THD) using few math operations, a low-pass filter (LPF), and a grid monitoring system able to provide the fundamental and harmonics components ...
