PROBLEM TO BE SOLVED: To provide a power supply system and abnormality detection method for detecting one location of disconnection having occurred in an annular signal line.SOLUTION: A power supply system comprises: one or more monitoring devices 11 to which power is supplied from an annular power line composed of power lines connected annularly and which monitor states of power storage units 15; and a control device 1 which controls the monitoring devices 11. The control device 1 includes: a first power distribution line 2 constituting part of the annular power line; a second power distribution line 3 connected to a power supply source and the first power distribution line 2; and a switching unit 5 which switches supply and interception of power supplied from the power supply source. The monitoring device 11 includes: a third power distribution line 12 constituting part of the annular power line; and a fourth power distribution line 13 which is connected to the third power distribution line 12 and supplies power to a load 14 included in the monitoring device 11.SELECTED DRAWING: Figure 1 |
