摘要

A power distribution system for an automatic fixed point floating structure has a plurality of buses including a first bus capable of connecting the load, and a plurality of switches including a first switch and a second switch, wherein the plurality of buses switch between the plurality of switches The first bus is connected between the first switch and the second switch, and the first current flowing in the direction of the first bus through the first switch is longer than the predetermined duration If the second current that exceeds the predetermined current threshold and flows in the direction toward the first bus through the second switch exceeds a predetermined current threshold longer than the predetermined duration, the power distribution system opens the first switch and at the same time A second switch is opened to separate the first bus from the ring.
