Abstract:
(EN) According to the present invention, a first converter converts input power into DC power of a prescribed voltage. A second converter has a power storage device, and converts, into AC power, the DC power supplied from the first converter via a DC link which is connected to the DC side of the first converter. A protection device, which is connected between the second converter and an AC system, has a switching unit that sets the connection between the second converter and the AC system to be in a connected state or in a disconnected state, and a load that consumes the AC power from the second converter when the switching unit achieves the disconnected state.
(FR) Selon la présente invention, un premier convertisseur convertit une puissance d'entrée en une puissance CC d'une tension prescrite. Un second convertisseur comprend un dispositif de stockage d'énergie, et convertit, en puissance CA, la puissance CC fournie par le premier convertisseur par l'intermédiaire d'une liaison CC qui est reliée au côté CC du premier convertisseur. Un dispositif de protection, qui est relié entre le second convertisseur et un système CA, est pourvu d'une unité de commutation qui établit la liaison entre le second convertisseur et le système CA de façon à être dans un état connecté ou dans un état déconnecté, et d'une charge qui consomme le courant alternatif provenant du second convertisseur quand l'unité de commutation atteint l'état déconnecté.
(JA) 第1の変換器は、入力電力を所定電圧の直流電力に変換する。第2の変換器は、蓄電デバイスを有し、前記第1の変換器の直流側に接続された直流リンクを介して前記第1の変換器から供給される直流電力を交流電力に変換する第2の変換器であって、蓄電デバイスを有する。保護装置は、前記第2の変換器と交流系統との間に接続される保護装置であって、前記第2の変換器と前記交流系統との間の接続を接続状態又は遮断状態にする開閉部と、前記開閉部が遮断状態とされた場合に前記第2の変換器からの交流電力を消費する負荷とを有する。
