Embodiment 1

[0023] A supercapacitor backup power system for DTU power distribution terminals, by reducing the total capacity of the supercapacitor modules required by the backup power system and optimizing the power configuration of the power management module required by the backup power system, the cost of the supercapacitor backup power system is fully reduced , Improve the reliability and stability of the backup power system of the existing DTU power distribution terminal.

Embodiment 2

[0025] Said reducing the total capacity of the supercapacitor module required by the backup power system and optimizing the power configuration of the power management module required by the backup power system refers to: on the one hand, realize the interaction between the backup power system and the DTU core unit, and the power distribution by the DTU The terminal manages the output power of the backup power system according to its own working status, and then controls the power consumption of the backup power system; The power consumption of the system itself.

Embodiment 3

[0027]As a concrete manifestation of Embodiment 2, the DTU power distribution terminal supercapacitor backup power supply system includes three parts: a supercapacitor module, a charging and discharging management unit, and an electrolytic capacitor bank, wherein the charging and discharging management unit is composed of an AC / DC power supply, an operating DC The / DC power supply and the control DC / DC power supply are jointly formed. The AC AC / DC power supply has two outputs, and the two outputs are isolated from each other. When the AC is online, one of them supplies power to each module inside the DTU power distribution terminal, and the other supplies power to the supercapacitor. Module charging, at the same time, the AC AC / DC power supply has its own status signal output function, and its output status information is the input AC working status, output circuit I working status and output circuit II working status, and the output status information is provided to the core of...

Abstract

The invention discloses a supercapacitor backup power supply system for a DTU power distribution terminal. By reducing the total capacity of the supercapacitor module required by the backup power supply system and optimizing the power configuration of the power management module required by the backup power supply system, the backup capacity of the supercapacitor can be fully reduced. The cost of the power system improves the reliability and stability of the backup power system of the existing DTU power distribution terminal. The state information of the components of the charging and discharging management unit of the present invention can be reported in real time, and can continuously track the operating state of the power supply module inside the system, which provides great convenience for the maintenance and repair of the backup power supply system, and the state information of the AC power supply and the state information of the supercapacitor module are fused In the power module, the DTU power distribution terminal only communicates with each power module in the backup power system. The working state of the backup power system is controllable, the fault identification is simple, and the cost is low. It can give full play to the advantages of the super capacitor and provide DTU power distribution terminals. More simple and powerful backup power protection.

Description

technical field [0001] The invention relates to a power distribution terminal backup power supply system, in particular to a DTU power distribution terminal supercapacitor backup power supply system. Background technique [0002] The DTU power distribution terminal is the key equipment in the intelligent power distribution link. Its operating status is directly related to the power consumption experience of thousands of users, and even more related to the operation safety of the entire power distribution network. In the event of a distribution line failure or power loss, a reliable backup power supply for the DTU distribution terminal is particularly important. [0003] At present, most DTU power distribution terminals use lead-acid batteries as backup power. However, the actual working life of lead-acid batteries is not ideal, and professional and technical personnel are required to carry out regular targeted maintenance, which brings great inconvenience to the operation an...
