The invention relates to the technical field of power supply, and discloses a standby power supply device and a standby power supply system. The device comprises an energy storage module which is used for providing a standby power supply for a plurality of power distribution devices, a monitoring module which is electrically connected with the energy storage module and is used for acquiring monitoring information of the energy storage module, and a charging control module which is electrically connected with the monitoring module and is used for controlling the energy storage module to output electric energy to each power distribution device according to the monitoring information. The energy storage module is used as the standby power supply of a plurality of power distribution devices, the monitoring module is used for monitoring the working state of the energy storage module, the charging control module is used for controlling the output electric energy of the energy storage module, and the electric energy output by the energy storage module to each power distribution device is controlled. The standby power supply device has the advantages of centralized management and control, low device operation risk, low investment cost, low maintenance cost and the like by using the functional modules, and solves the problems that the maintenance cost is increased and the maintenance efficiency is reduced due to the fact that the power distribution devices are each provided with a standby power supply.
Description
technical field [0001] The invention relates to the technical field of power supply, in particular to a backup power supply device and a backup power supply system. Background technique [0002] With the continuous development of smart grid and the accumulation of long-term operation practice, the number of automation equipment in the power distribution room is gradually increasing. At present, except for a very small number of power distribution rooms that have installed DC screen cabinets as the backup power supply for relay protection devices, most public power rooms lack a backup power supply system. Automatic terminals and smart devices are equipped with backup power, which greatly increases maintenance costs and reduces maintenance efficiency. Contents of the invention [0003] Based on this, it is necessary to provide a backup power supply device and a backup power supply system for the lack of a backup power supply system in most public power rooms, and the distri...
