Abstract
(EN)
The present disclosure relates to a STATCOM arrangement (1) comprising an MMC (2) and a transformer arrangement (3) arranged to be an interface between the MMC (2) and an AC grid. The MMC (2) is connected in a wye topology with a plurality of converter arms, one for each phase of the AC grid, each arm comprising a plurality of chain-linked converter cells. The transformer arrangement (3) is arranged to interface each of the arms of the MMC (2) with a respective phase of the grid, and arranged to for each of the converter arms produce leakage reactance resulting in reactance in series with the arm which obviates the need for a phase reactor connected in series with said arm.
(FR)
La présente invention concerne un agencement de STATCOM (1) comprenant un MMC (2) et un agencement de transformateur (3) agencé pour être une interface entre le MMC (2) et un réseau électrique en CA. Le MMC (2) est connecté dans une topologie en étoile pourvue d’une pluralité de bras de convertisseurs, un pour chaque phase du réseau électrique en CA, chaque bras comprenant une pluralité de cellules de convertisseurs reliées en chaîne. L’agencement de transformateur (3) est agencé pour interfacer chacun des bras du MMC (2) avec une phase respective du réseau électrique, et agencé pour produire pour chacun des bras convertisseur une réactance de fuite résultant en la réactance en série avec le bras, ce qui annule le besoin d’une réactance de phase connectée en série avec ledit bras.
