Distributed power generation system with inrush current suppression circuit and inrush current suppression circuit

摘要

PROBLEM TO BE SOLVED: To provide a distributed power generation system including an inrush current suppression circuit and an inrush current suppression circuit. An inrush current suppression circuit 50 is provided in an independent power supply device 30 that receives a supply of generated power generated by a fuel cell power generation device 10, the supply of system power 40 from the power system is stopped, and the self-sustaining power supply device When the self-supporting load 63 is connected to the self-supporting outlet 35, the inrush current from the self-supporting load can be suppressed. The inrush current suppression circuit includes a first connection line 53 connecting an independent side supply line 37 connecting the distributed power generation device and the independent power supply device and an independent connection line 39 connected to the independent outlet, and an independent side supply line. The second connection line 55 that connects the self-supporting connection line via a resistor 56 that can suppress the inrush current from the self-supporting load, and the connection between the self-supporting side supply line and the self-supporting connection line are the first connection line and the second. A switch 51 for switching between the connection line and the connection line is provided. [Selection diagram] Fig. 1
