Title (EN) POWER CONVERSION DEVICE
(FR) DISPOSITIF DE CONVERSION D'ALIMENTATION
(JA) 電力変換装置
Abstract:
(EN) A power conversion device configured to be interconnected to an electric power system through a transformer, and configured to have unit converters cascade-connected, wherein reactors will become unnecessary, and the volume and weight thereof will be reduced. The power conversion device (101), interconnected with a three-phase power system through the transformer (105), and giving and receiving apparent or reactive power with the three-phase power system (100), has the secondary coils of the transformer (105) made to be open coils having six terminals (106 to 111); has a first conversion group (112), consisting of a circuit that had three conversion arms (113 to 115) made to have a star connection, connected to three terminals (106 to 108) of the secondary coils; and has a second conversion group (116), consisting of a circuit that had three different conversion arms (117 to 119) made to have a star connection, connected to three terminals (109 to 111) of the secondary coils; and also has the neutral point (the point where the star connection is made) (121) of the first conversion group (112), and the neutral point (122) of the second conversion group (116) made to be the output terminals of the power conversion device.
(FR) La présente invention concerne un dispositif de conversion d'alimentation configuré pour être interconnecté avec un système d'alimentation électrique par l'intermédiaire d'un transformateur et configuré pour être doté de convertisseurs de puissance connectés en cascade, rendant inutile l'utilisation de réacteurs, et dont le volume et le poids sont réduits. Le dispositif de conversion d'alimentation (101), interconnecté avec un système d'alimentation triphasé par l'intermédiaire du transformateur (105), et échangeant avec le système d'alimentation triphasé (100) une puissance électrique apparente ou réactive, possède des bobines secondaires du transformateur (105) constituées en bobines ouvertes dotées de six terminaux (106 à 111) ; le dispositif de conversion d'alimentation possède un premier groupe de conversion (112), constitué d'un circuit ayant trois bras de conversion (113 à 115) conçus pour former une connexion en étoile, connectés à trois terminaux (106 à 108) des bobines secondaires ; le dispositif de conversion d'alimentation possède, en outre, un deuxième groupe de conversion (116), constitué d'un circuit ayant trois bras de conversion différents (117 à 119) conçus pour former une connexion en étoile, connectés à trois terminaux (109 à 111) des bobines secondaires ; le dispositif de conversion d'alimentation possède également le point neutre (le point de formation de la connexion en étoile) (121) du premier groupe de conversion (112) et le point neutre (122) du deuxième groupe de conversion (116) prévus pour être les terminaux de sortie du dispositif de conversion d'alimentation.
(JA)  変圧器を介して電力系統に連系し、単位変換器をカスケード接続して構成される電力変換装置において、リアクトルを不要とし、体積・重量を低減する。 変圧器(105)を介して三相電力系統(100)に連系し、三相電力系統(100)と有効または無効電力を授受する電力変換装置(101)であって、変圧器(105)の二次巻線をオープン巻線として6端子(106~111)とし、該二次巻線の3つの端子(106~108)に3台の変換器アーム(113~115)をスター結線した回路からなる第1の変換器グループ(112)を接続し、該二次巻線の3つの端子(109~111)に別の3台の変換器アーム(117~119)をスター結線した回路からなる第2の変換器グループ(116)を接続し、第1の変換器グループ(112)の中性点(スター結線した点)(121)と第2の変換器グループ(116)の中性点(122)を、それぞれ該電力変換装置の出力端子とする。
