A distributed power generation system of the present invention is a distributed power generation system connected to an electric wire (33) connecting a power supply utility (21) to a power load (24), in which a second power generation device (29) is connected to the electric wire (33) in a position between the power supply utility (21) and a first connection point (24), the distributed power generation system comprising: an inverter (25) connected to the first connection point (23); a first power generation device (27), a current sensor (22) provided on the electric wire (33) in a position between the utility power supply (21) and the first connection point (23); and a controller (26) wherein in a case where a current flowing in a direction from the first connection point (23) to the power supply utility (21) is a positive current, the controller (26) determines that there is an abnormality in an installation state of the current sensor (22), or performs notification of the abnormality in the installation state ofthe current sensor (22), when an electric power difference obtained by subtracting electric power consumed in the power load (24) from the electric power output from the inverter (25) is greater than a first threshold which is greater than 0. |
