Title (EN) ARRANGEMENT, METHOD AND COMPUTER PROGRAM PRODUCT CONCERNED WITH TAPPING OF POWER FROM A DC POWER LINE TO AN AC POWER LINE
(FR) AGENCEMENT, PROCÉDÉ ET PRODUIT DE PROGRAMME INFORMATIQUE RELATIFS AU PRÉLÈVEMENT D'ÉNERGIE D'UNE LIGNE D'ALIMENTATION CC POUR L'ENVOYER VERS UNE LIGNE D'ALIMENTATION CA
Abstract:
(EN) An arrangement (23) for tapping power from a DC power line (12) to an AC power line comprises power transfer modules (24A, 24B, 24C) between two DC potentials, each comprising a first branch with a string of converter cells (CA1, CA2, CB1, CB2, CC1, CC2) in parallel with a second branch comprising a capacitor (Csa, Csb, Csc) and being connected to an AC phase (22A, 22B, 22C). There is at least one control unit (26A, 26B, 26C) that controls the arrangement considering one or more of a) distributing appropriate AC and DC voltages in converter output voltages of all series connected modules, b) maintaining/setting cell capacitor voltages in specific range and allowing boost mode operation, c) performing possible balancing of the introduced capacitor and.d) employing an alternate approach of using passive filters to mitigate low order harmonics.
(FR) La présente invention concerne un agencement (23) pour prélever de l'énergie d'une ligne d'alimentation CC (12) et l'envoyer vers une ligne d'alimentation CA, qui comprend des modules de transfert d'énergie (24A, 24B, 24C) entre deux potentiels CC, comprenant chacun une première branche avec une chaîne de cellules convertisseurs (CA1, CA2, CB1, CB2, CC1, CC2) en parallèle à une deuxième branche comprenant un condensateur (Csa, Csb, Csc) et connectée à une phase CA (22A, 22B, 22C). Il y a au moins une unité de commande (26A, 26B, 26C) qui commande l'agencement en considérant un ou plusieurs de a) la distribution de tensions CA et CC appropriées aux tensions de sortie des convertisseurs de tous les modules connectés en série, b) le maintien/établissement de tensions de condensateur de cellule dans une plage spécifique et l'autorisation d'un fonctionnement en mode survolteur, c) l'exécution d'un éventuel équilibrage du condensateur introduit et d) l'utilisation d'une approche alternative à l'utilisation de filtres passifs pour la limitation des harmoniques d'ordre bas.
