Abstract:
(EN) The present invention relates to an uninterruptible power supply system comprising an energy storage system (ESS). The uninterruptible power supply system, according to the present invention, comprises an ESS and is connected to a grid. The uninterruptible power supply system comprises: a first converter for converting an alternating current voltage of the grid into a direct current voltage; a second converter connected in series to the first converter, for converting the direct current voltage outputted from the first converter into an alternating current voltage and transferring same to a load; the ESS comprising a battery electrically connected to a node between the first converter and the second converter, for performing charging and discharging; and a PLC for receiving the operation statuses of the first and second converters, and on the basis thereof, controlling the operation of the uninterruptible power supply system, wherein the PLC determines the operation mode of the ESS by using the received operation statuses of the first and second converters.
(FR) La présente invention concerne un système d'alimentation sans coupure comprenant un système de stockage d'énergie (ESS). Le système d'alimentation sans coupure, selon la présente invention, comprend un ESS et est connecté à une grille. Le système d'alimentation sans coupure comprend : un premier convertisseur pour convertir une tension de courant alternatif de la grille en une tension de courant continu; un second convertisseur connecté en série avec le premier convertisseur, et convertissant la tension de courant continu délivrée en sortie par le premier convertisseur en une tension de courant alternatif pour le transférer à une charge; l'ESS connecté électriquement à un nœud entre le premier convertisseur et le second convertisseur, et comprenant une batterie pour effectuer une charge et une décharge; et un PLC pour recevoir les états de fonctionnement des premier et second convertisseurs, et, sur la base de ceux-ci, commander le fonctionnement du système d'alimentation sans coupure, le PLC déterminant le mode de fonctionnement de l'ESS en utilisant les états de fonctionnement reçus des premier et second convertisseurs.
(KO) 본 발명은 에너지 저장 장치를 포함하는 무정전 전원 공급 시스템에 관한 것이다. 본 발명의 무정전 전원 공급 시스템은, 에너지 저장 장치(ESS)를 포함하고, 계통에 연결된 무정전 전원 공급 시스템에 있어서, 상기 계통의 교류 전압을 직류 전압으로 변환하는 제1 컨버터, 상기 제1 컨버터와 직렬 연결되고, 상기 제1 컨버터에서 출력된 직류 전압을 교류 전압으로 변환하여 부하에 전달하는 제2 컨버터, 상기 제1 컨버터 및 상기 제2 컨버터 사이의 노드에 전기적으로 연결되어 충방전을 수행하는 배터리를 포함하는 에너지 저장 장치, 및 상기 제1 및 제2 컨버터의 동작 상태를 수신하고, 이를 기초로 상기 무정전 전원 공급 시스템의 동작을 제어하는 PLC를 포함하되, 상기 PLC는, 수신된 상기 제1 및 제2 컨버터의 동작 상태를 이용하여 상기 에너지 저장 장치의 동작 모드를 판단한다.
