摘要 |
The invention relates to a decentralized power supply device comprising means for feeding electrical energy of an especially regenerative energy source (1) to a power supply system (L1<SUB>Netz</SUB>, N<SUB>Netz</SUB>) and protective devices (3). The energy source (1) is connected to a control (4) which is used to connect at least a part of the protective devices (3) to the power supply system (L1<SUB>Netz,</SUB> N<SUB>Netz</SUB>). The controlled connection of the protective devices (3) allows to separate the protective devices (3) from the power supply system (L1<SUB>Netz</SUB>, N<SUB>Netz</SUB>), thereby reducing power consumption of the protective devices (3) and increasing overall efficiency of the system. |
