Title (EN) METHOD FOR DETECTING ISLANDING CONDITIONS FOR A DC/AC CONVERTER APPARATUS AND A DC/AC CONVERTER APPARATUS THEREOF
(FR) PROCÉDÉ DE DÉTECTION DE CONDITIONS D'ÎLOTAGE POUR UN APPAREIL CONVERTISSEUR CC/CA ET APPAREIL CONVERTISSEUR CC/CA ASSOCIÉ
Abstract:
(EN) Method for detecting an islanding condition of a grid connected energy conversion system and related DC/AC converter apparatus adapted to optimize performance in terms of preservation of the power quality, provide synchronized frequency perturbation for all the inverters of a plant, provide shut down capability within the time requested by utilities and safety standards and provide immunity to grid frequency fluctuations.
(FR) La présente invention concerne un procédé de détection d'une condition d'îlotage d'un système de conversion d'énergie connecté à un réseau électrique et un appareil convertisseur CC/CA associé conçu pour optimiser les performances en termes de préservation de la qualité de l'énergie, fournir une perturbation de fréquence synchronisée à tous les onduleurs d'une installation, fournir une capacité de coupure dans les délais impartis par les services publics et les normes de sécurité et fournir une immunité aux fluctuations de fréquence de réseau électrique.
