| contents | Reassessment and proposal of synchronization scheme for grid connected static converters under disturbed utility Giuseppe Buja Osley López González Ingeniería grid connected three phase converters Active compensators distributed generation The paper starts by casting new light to the existing Phase Lock Loop (PLL) schemes used to synchronize the static converters with the grid under utility disturbances. Two approaches are pursued to detect the fundamental harmonic of the positive - sequence component o f the grid voltages in presence of the disturbances. Arithmetical approaches improve the operation of the basic PLL circuit by making robust the PLL algorithm. Structural approaches improve the operation of the basic PLL circuit by adding a block intended to cope with the disturbances. This paper considers the structural approach and shows that it works by either post processing the detected grid quantities or preprocessing the grid voltages. Afterwards, the paper proposes an improved PLL scheme termed as d ouble processing (DP) PLL scheme since it includes preprocessing and post processing functionalities. By properly designing the scheme parameters, it is proved that the proposed scheme exhibits superior robustness against the utility disturbances. 2014 artículo científico 1815-5901 https://www.redalyc.org/articulo.oa?id=329132445016 en http://www.redalyc.org/revista.oa?id=3291 Ingeniería Energética application/pdf Universidad Tecnológica de La Habana "José Antonio Echeverría" (CUJAE) Ingeniería Energética (Cuba) Num.3 Vol.XXXV |
