storage battery
The battery pack is an independent and reliable power source. It is not affected by the AC power supply. In the event of any accident in the power plant or substation, even when the AC power supply of the whole plant and the whole station is out of power, it can still guarantee the power in the DC system. The electrical equipment works reliably and continuously, and the voltage is stable; at the same time, it can also be used as the emergency lighting power supply for the whole plant and the whole station, and it is the last barrier to ensure the uninterrupted power supply.
