PROBLEM TO BE SOLVED: To provide a power generation system capable of suppressing consumption of unnecessary control power and suppressing adverse influence on a load, with a simple configuration.SOLUTION: A power generation system comprises a power supply switching device 3 comprising: a first relay 31 driven by interconnection power; a second relay 32 driven by autonomous power; a first relay first B contact point switch 312 connected in series to the second relay 32; a second relay B contact point switch 322 connected in series to the first relay 31; a first relay A contact point switch 311 for connecting/disconnecting the interconnection power; a second relay A contact point switch 321 for connecting/disconnecting the autonomous power; and an autonomous operation switch 331 which is connected in series to the second relay 32 and first relay first B contact point switch 312, and is made to be in a connection state according to operation of a user when the interconnection power is not input and is made to be in a disconnection state according to operation of the user. The power generation system further comprises a control device 2 for making a power generator 12 perform autonomous operation when the autonomous operation switch 331 becomes in the connection state. |
