WIPO Patent Application WO/2023/223434
Kind Code:
A1
Abstract:
In the present invention, a power feed device and a distributed power supply linked with a commercial power grid perform autonomous operation appropriately during power outage. This power feed system includes a distributed power supply, a power feed device, and a full load distribution board. The full load distribution board comprises: a switch having a first input terminal through which a feeding power from the commercial power grid is inputted, a second input terminal through which an autonomous operation output from the distributed power supply is inputted, and an output terminal through which a feeding power to a load is outputted; a first electric path for connecting a grid connection part and the first input terminal; a first connection part which is provided in the first electric path and to which a normal operation output from the distributed power supply is inputted; a second connection part which is provided between the first connection part and the switch and to which the normal operation output from the power feed device is inputted; a first current detector connected to the distributed power supply to detect a current fed from the commercial power grid to the first electric path; and a second current detector connected to the power feed device to detect a current flowing through the first electric path which connects the first connection part and the second connection part.
