To provide a power supply monitoring device capable of making a power supply in a power supply system redundant and allowing the power from each redundant power supply to be efficiently used.SOLUTION: A power supply monitoring device 21 includes; a first circuit ES1 that has a first power supply 10 and a second circuit ES2 that has a second power supply 16. The first circuit and the second circuit are capable of being connected each other via a switch SWA between the circuits. The power supply monitoring device is applied to a power supply system 100 that closes the switch between the circuits to supply power to electrical loads connected to each circuit under a state system is running. The first power supply has a voltage generation unit 12, and the second power supply has a power storage unit 16 that is chargeable by the voltage generation unit. The power supply monitoring device includes: a charging control unit 25 that is configured so as to, under a state the system running, close the switch between the circuits to charge the power storage unit by the voltage generation unit; and a dark current supply unit 24 that is configured so as to, under the system halt condition, close the switch between the circuits to supply a dark current to the electrical load from the power storage unit.SELECTED DRAWING: Figure 1

    【課題】電源システムにおける電源を冗長化しつつ、冗長化した各電源の電力を効率的に利用できる電源監視装置を提供すること。【解決手段】電源監視装置21は、第1電源10を有する第1系統ES1と、第2電源16を有する第2系統ES2とを備え、第1系統及び第2系統が系統間スイッチSWAにより互いに接続可能となっており、システム稼働状態下において、系統間スイッチを閉鎖して、各系統に接続されている電気負荷に対する電力供給を行う電源システム100に適用される。第1電源は、電圧生成部12を有し、第2電源は、電圧生成部により充電可能な蓄電装置16を有する。電源監視装置は、システム稼働状態下において、系統間スイッチを閉鎖して電圧生成部により蓄電装置の充電を行わせる充電制御部25と、システム停止状態下において、系統間スイッチを閉鎖して蓄電装置から電気負荷に暗電流供給を行わせる暗電流供給部24と、を備える。【選択図】 図1
