The invention relates to a DC power distribution system (100) comprising a plurality of power consumer clusters (120), each power consumer cluster comprising at least one power consumer (180). The power consumer clusters (120) are arranged in a ring structure having a common LV-DC ring bus (102). Each power consumer (180) is connected to the LV-DC ring bus (102). The DC power distribution system (100) also includes a plurality of normally open loop switches (110). Each power consumer cluster (120) is separated from its adjacent power consumer cluster by a normally open loop switch (110). Each power consumer cluster (120) is fed by an MV-DC/DC converter (130), which in turn is fed by an MV-AC/DC converter (145) connected to an MV-AC power grid (104).
本发明涉及一种DC配电系统(100),包括多个电力用户群集(120),每个电力用户群集包括至少一个电力用户(180)。电力用户群集(120)被布置为具有公共LV‑DC环形总线(102)的环形结构。每个电力用户(180)被连接到LV‑DC环形总线(102)。DC配电系统(100)还包括多个常开环开关(110)。每个电力用户群集(120)通过一个常开环开关(110)与其相邻的电力用户群集分开。每个电力用户群集(120)由MV‑DC/DC转换器(130)馈电,MV‑DC/DC转换器(130)又由连接到MV‑AC电网(104)的MV‑AC/DC转换器(145)馈电。
