Device and method for coordinating power supply systems of two low-voltage transformer areas

The invention provides a two-low-voltage transformer area power supply system coordination device. The device comprises a main control module, a data acquisition module and a power support module, detects power distribution data in real time, and controls the power support module to provide short-time power support for a non-fault low-voltage transformer area through the main control module, so the power supply reliability of the power supply system is improved. The invention also provides a two-low-voltage transformer area power supply system coordination method. The method comprises the steps of dividing the two low-voltage transformer areas into a first transformer area and a second transformer area, collecting power distribution data of the two low-voltage transformer areas, comparing the power distribution data of the two low-voltage transformer areas, screening out a fault transformer area, and discharging the energy storage system for short-time operation of a conventional load in the fault transformer
