DC DISTRIBUTION SYSTEM AND METHOD FOR DISTRIBUTING POWER

The invention is related to a DC distribution system (100) comprising a plurality of power consumer clusters (120) each comprising at least one power consumer (180). The power consumer clusters (120) are arranged as a ring structure with a common LV-DC ring bus (102). Each power consumer (180) is connected to the LV-DC ring bus (102). The DC distribution system (100) further comprises a plurality of normal-open ring switches (110). Each power consumer cluster (120) is separated from its adjacent power consumer clusters by one of the normal-open ring switches (110). Each power consumer cluster (120) is fed by a MV-DC/DC converter (130), which in turn is fed by a MV-AC/DC converter (145) connected to a MV-AC grid (104).
