Intelligent energy storage type emergency power supply system

Abstract

The invention provides an intelligent energy storage type emergency power supply system, and relates to power supply systems. In the system, the input end of a battery charger is connected with the input end of a 380VAC main power supply through a rectifier switch, the output end of the battery charger is connected with one end of a battery switch and the input end of an inverter, the other end of the battery switch is connected with a backup lithium-ion power supply, the output end of the inverter is connected with the inversion input end of a static transfer switch, the bypass input end of the static transfer switch is connected with the input end of the 380VAC main power supply through a commercial power bypass switch, the output end of the static transfer switch is connected with the input end of an output switch, the output end of the output switch is connected with a load, one end of a maintenance bypass switch is connected with the input end of the 380VAC main power supply, and the other end of the maintenance bypass switch is directly connected with the load. The intelligent energy storage type emergency power supply system is an energy storage type power supply integrating charging, discharging and monitoring, and has the advantages of being environmentally friendly, energy saving, free of pollution, and capable of supplying power incessantly.

Description

technical field [0001] The invention relates to a power supply system, in particular to an intelligent energy storage type emergency power supply system. Background technique [0002] With the development of society, the requirements for the reliability of power supply are getting higher and higher. Once the power supply system of some important facilities suddenly breaks down and the power supply is interrupted, it will disrupt the normal order of society and even cause major political influence and economic losses. However, power failures are sudden, and power outages must be considered. Therefore, it is necessary to ensure uninterrupted power supply, that is, consider emergency power supply. Important power supply sites, emergency repairs, emergency disaster relief, etc. are also in urgent need of emergency power. [0003] The emergency power sources widely used at present include diesel engine power generation and lead-acid battery as backup emergency power source. Amo...
