(JA) 系統連系システム
Abstract:
(EN) The present disclosure addresses the problem of applying a ground voltage to an electrode of a distributed power supply. This system interconnection system (100) is provided with an inverter (3). The inverter (3) is connected between a distributed power supply (1) and a power system (6), and converts DC power from the distributed power supply (1) into AC power. The system interconnection system (100) is further provided with a backflow prevention diode (D1). The backflow prevention diode (D1) is provided on a current path including at least a portion of a circuit on a distributed power supply (1)-side from the perspective of the inverter (3), and prevents a leakage current that flows to a reference potential (Vb1) through the current path.
(FR) La présente invention aborde le problème de l'application d'une tension de mise à la terre à une électrode d'une alimentation électrique distribuée. Ce système d'interconnexion de système (100) est pourvu d'un onduleur (3). L'onduleur (3) est raccordé entre une alimentation électrique distribuée (1) et un système d'alimentation (6) et convertit la puissance en courant continu provenant de l'alimentation électrique distribuée (1) en puissance en courant alternatif. Le système d'interconnexion de système (100) est en outre pourvu d'une diode anti-reflux (D1). La diode anti-reflux (D1) est disposée sur un trajet de courant comprenant au moins une partie d'un circuit côté alimentation électrique distribuée (1) à partir de la perspective de l'onduleur (3) et empêche un courant de fuite qui circule jusqu'à un potentiel de référence (Vb1) à travers le trajet de courant.
(JA) 本開示の課題は、分散型電源の電極に対地電圧が印加され難くすることにある。系統連系システム(100)は、インバータ(3)を備える。インバータ(3)は、分散型電源(1)と電力系統(6)との間に接続され、分散型電源(1)からの直流電力を交流電力に変換する。系統連系システム(100)は、逆流阻止ダイオード(D1)を更に備える。逆流阻止ダイオード(D1)は、インバータ(3)から見て分散型電源(1)側の回路の少なくとも一部を含む電流経路に設けられ、電流経路を通して基準電位(Vb1)に流れる漏洩電流を阻止する。
