Automatic switching type standby power supply access system based on mobile energy storage and control method thereof

Abstract

The invention provides an automatic switching type standby power supply access system based on mobile energy storage. The automatic switching type standby power supply access system comprises an original transformer area power distribution system, a mobile energy storage power supply system, a dual-power-supply automatic change-over switch and an important load. The invention further discloses a control method of the automatic switching type standby power supply access system based on mobile energy storage. The mobile energy storage power supply system is used for replacing a diesel generator set standby power supply in traditional power protection operation, the power supply electric energy quality of the standby power supply in the power protection operation is improved, and the power supply interval time in the power protection task is shortened. The control method provided by the invention can replace a diesel generator set in the traditional power protection operation, realizes full-automatic operation in the power protection operation, greatly shortens the power supply interval caused by the mains supply fault, and ensures that the power supply quality of the important load is high when the standby power supply supplies power.

Description

technical field [0001] The invention belongs to the technical field of mobile energy storage, and in particular relates to a mobile energy storage-based self-injection backup power access system and a control method thereof. Background technique [0002] In the traditional power field power maintenance work, the main power supply and diesel generator dual power supply are equipped with dual power automatic switch to ensure the sustainability of power supply in important power consumption places, but the power quality of diesel generator power supply is poor, and the load Fluctuations will lead to fluctuations in the power supply voltage and frequency of the diesel generator set. At the same time, when the mains power is disconnected due to a fault during the power maintenance operation, the maintenance workers must actively start the diesel generator set to stabilize and then output AC power. At this time, the dual power supply will automatically switch When the switch detec...

Problems solved by technology

[0002] In the traditional electric power field, the power supply of mains power supply and diesel generator dual power supply is equipped with dual power supply automatic switch to ensure the sustainability of power supply in important power consumption places, but the power quality of diesel generator power supply is poor, and the load Fluctuations will lead to fluctuations in the power supply voltage and frequency of the diesel generator set. At the same time, when the mains power is disconnected due to a fault during the power maintenance operation, the maintenance workers must actively start the diesel generator set to stabilize and then output AC power. At this time, the dual power supply will automatically switch When the switch detects the voltage of the backup power supply, it will switch to the backup power supply for power supply. Only after the switching is completed, the power protection load can be powered and can operate normally. This power supply operation process is cumbersome and time-consuming.
