Title (EN) CONTROL DEVICE OF POWER CONVERSION SYSTEM
(FR) DISPOSITIF DE COMMANDE DE SYSTÈME DE CONVERSION DE COURANT
(JA) 電力変換システムの制御装置
Abstract:
(EN) Control devices (30a, 30b, 40) are applied to a power conversion system (10) comprising a first DDC (10a) and a second DDC (10b) connected in parallel to a common electric supply target (60). So that output current is equalized, the control devices (30a, 30b, 40) implement equalization control to correct at least one of the voltage command value of the first DDC (10a) and the voltage command value of the second DDC (10b) using an output correction voltage VLB. Also, under implementation of the equalization control, on the basis of the output correction voltage VLB, a determination is made of whether a disconnection abnormality has occurred for either of the output side of the first DDC (10a) and the output side of the second DDC (10b).
(FR) L'invention concerne des dispositifs de commande (30a, 30b, 40) qui sont appliqués à un système de conversion de courant (10) comprenant un premier DDC (10a) et un second DDC (10b) connectés en parallèle à une cible d'alimentation électrique commune (60). De façon que le courant de sortie soit égalisé, les dispositifs de commande (30a, 30b, 40) mettent en oeuvre une commande d'égalisation pour corriger la valeur de commande de tension du premier DDC (10a) et/ou la valeur de commande de tension du second DDC (10b) à l'aide d'une tension de correction de sortie VLB. De plus, lors de la mise en oeuvre de la commande d'égalisation, sur la base de la tension de correction de sortie VLB, il est déterminé si une anomalie de déconnexion s'est produite pour l'un ou l'autre du côté de sortie du premier DDC (10a) et du côté de sortie du second DDC (10b).
(JA) 制御装置(30a,30b,40)は、共通の給電対象(60)に対して並列に接続された第1DDC(10a)及び第2DDC(10b)を備える電力変換システム(10)に適用される。制御装置(30a,30b,40)は、出力電流が均等化されるよう第1DDC(10a)の電圧指令値及び第2DDC(10b)の電圧指令値の少なくともいずれかを出力補正電圧VLBにより補正する均等化制御を実施する。また、均等化制御の実施下において、出力補正電圧VLBに基づいて、第1DDC(10a)の出力側と、第2DDC(10b)の出力側とのいずれに断線異常が生じているかを判定する。
