Title (EN) MICROGRID SYSTEM, AND METHOD FOR MANAGING MALFUNCTION
(FR) SYSTÈME DE MICRORÉSEAU ET PROCÉDÉ DE GESTION DE DYSFONCTIONNEMENT
(KO) 마이크로그리드 시스템 및 고장 처리 방법
Abstract:
(EN) A microgrid system according to the present invention is provided with: a plurality of decentralized power sources; a plurality of decentralized subordinates; paths connecting the decentralized power sources and subordinates; and a control apparatus for controlling the operation of the decentralized power sources, wherein at least one among the decentralized power sources converts power generated by a power generator to alternating current power appropriate for the microgrid, and supplies thereto, and is provided with an active PCS having a cut-off means for cutting off connection to the microgrid in abnormal situations, and the control apparatus, when a malfunction is sensed in the microgrid, can gradually increase the voltage outputted from the active PCS and manage the malfunction.
(FR) La présente invention concerne un système de microréseau qui comprend : une pluralité de sources d'alimentation décentralisées; une pluralité de subordonnés décentralisés; des chemins connectant les sources d'alimentation décentralisées et les subordonnés; et un appareil de commande pour commander le fonctionnement des sources d'alimentation décentralisées. Au moins l'une des sources d'alimentation décentralisées convertit la puissance générée par un générateur de puissance en une puissance de courant alternatif appropriée pour le microréseau, et la fournit à celui-ci, et comprend un PCS actif ayant un moyen de coupure pour couper la connexion au microréseau dans des situations anormales, et l'appareil de commande, lorsqu'un dysfonctionnement est détecté dans le microréseau, peut augmenter progressivement la tension fournie par le PCS actif et gérer le dysfonctionnement.
