Problems solved by technology

The battery has the disadvantages of short service life, long charging time, incomplete discharge, short maintenance cycle, and high environmental conditions. More importantly, the production process of the battery and the treatment process of the used battery are accompanied by pollution.
Flywheel energy storage can achieve fast response and high efficiency, but it needs to be used in conjunction with an internal combustion engine

Embodiment 1

[0035] figure 1 It is a structural schematic diagram of Embodiment 1 of the uninterrupted power supply method and the power supply system of the present invention. The monitoring and control unit 2 monitors the working status of each unit in real time (the dotted line in the figure is the monitoring connection line). The monitoring and control unit 2 is connected to the supercapacitor unit 7 and the liquid nitrogen power unit 9 through the control circuit, and the monitoring and control unit 2 that is always in the working state is used to dynamically monitor the mains 1, the supercapacitor unit 7 and the liquid nitrogen power unit 9 in real time. working status. When the mains 1 is working normally, the electrical equipment 5 consumes the mains power; part of the mains 1 charges the supercapacitor through the power electronic device 6, and the other part passes through the power electronic device 8 and the heat storage and heat exchange unit in the liquid nitrogen power unit...

Embodiment 2

[0040] figure 2 It is a schematic structural diagram of Embodiment 2 of the uninterruptible power supply system of the present invention, its main structure is the same as that of Embodiment 1, the difference is the working process of the liquid nitrogen power unit 9 . When the liquid nitrogen power unit 9 is started, the liquid nitrogen in the cryogenic storage tank 10 passes through the valve 11 and is pressurized in the liquid pump 12. This part of the fluid passes through the air cooler 13, and the ambient air is used to heat the high-pressure liquid nitrogen to obtain high-pressure nitrogen. This part of nitrogen absorbs heat through the heat storage and heat exchange unit 14, and first works through the high-pressure expander 15. This part of the gas absorbs heat through the heat storage and heat exchange unit 14 again, then enters the low-pressure expander 16 to expand and perform work, and finally is discharged outside.

Embodiment 3

[0043] image 3 It is a structural schematic diagram of Embodiment 3 of the uninterruptible power supply system of the present invention. This embodiment is a mobile power system, which can be used as vehicle power, etc., and its power source 9 is a liquid nitrogen power unit. Compared with Embodiment 1 and the implementation For the liquid nitrogen power unit of example 2, the power unit 9 in this system has two cases including heat storage unit and no heat storage unit; when the heat storage unit is included, this part of heat energy comes from stored electric energy or other forms of heat energy ; When the heat storage unit is not included, an air cooler is included before the expander and between stages, and the ambient energy is used to heat the gas before each stage expands. The power generated by the power unit 9 is mainly output in the form of shaft work, and the moving power is provided by the rotating wheel 23. When the power system needs to decelerate and brake, the...

Abstract

The invention discloses an uninterrupted power supply method and an uninterrupted power source system. The uninterrupted power source system mainly comprises a super capacitor energy storage unit, a liquid nitrogen power unit and a monitoring and control unit. When the commercial power supplies power normally, electric power is stored in the super capacitor and the liquid nitrogen power unit; when interruption of the electric power occurs, the super capacitor rapidly responds to supply power for electric equipment, and the liquid nitrogen power unit further starts to realize continuous long-time power supply; when the commercial power recovers to a normal state, the electrical network electric power is utilized to realize an energy storage process, moreover, liquid nitrogen in a low temperature liquid storage tank is supplemented according to demands. The uninterrupted power source system employs the super capacitor and the liquid nitrogen power unit and has advantages of rapid response, low carbon, environmental friendliness, long service life, low maintenance cost and strong adaptation capability.

Description

technical field [0001] The invention relates to an uninterrupted power supply method and a power supply system, in particular to an uninterrupted power supply method and a power supply system for coupling commercial power, a supercapacitor and a liquid nitrogen power unit. Background technique [0002] Uninterruptible power supply (Uninterruptible Power Supply, UPS) is a power supply equipment that includes components such as rectification, energy storage, inverter and switches. It is connected to the grid or local grid as an emergency power supply or backup power supply. When the grid power supply system is interrupted, the The equipment releases the stored electrical energy to achieve continuous power supply and maintain the normal operation of electrical equipment. Uninterruptible power supply has a wide range of applications in industrial, commercial and residential fields, mainly including communication, information technology, computer data center, industrial control, ...
