Intelligent power supply system

Abstract

The invention relates to the technical field of power supply devices, and discloses an intelligent power supply system which comprises a mains supply input end, a monitoring control unit, a switching power supply module, a standby power source, an inversion module and a switching output module. The mains supply input end is coupled with the monitoring control unit and is externally connected with the mains power grid, the monitoring control unit is coupled with the switching power supply module, the inversion module and the switching output module respectively, and the monitoring control unit is used for turning on the switching power supply module to charge the standby power source or turning on the inversion module to enable the standby power source to supply power according to operation states of the system. By means of the intelligent power supply system, power can be supplied in the mode of power grid load shifting, unbalance of power grid loads is effectively avoided, potential safety hazards of the power grid are effectively reduced, the effect of energy conservation and emission reduction is achieved, and electricity cost is effectively saved.

Description

Technical field [0001] The invention relates to the technical field of power supply equipment, in particular to an intelligent power supply system. Background technique [0002] For a long time, industrial production has to be carried out in accordance with certain work and rest rules. Industrial electrodes with large power consumption are unbalanced, and the supply of electricity during the day is in short supply. Power supply companies frequently restrict users' power consumption, which has a great impact on people's economy and life. ; Power consumption at night is oversupply, which not only poses a safety hazard to the power grid, but also causes a waste of energy. In order to reduce the load on the grid, power supply companies in many regions have adopted time-of-use pricing to encourage users to reduce power consumption during peak periods and mainly use power at night. But for equipment that requires continuous large-scale power consumption, it is obviously unrealistic to...

Problems solved by technology

[0004] However, the existing power supply system that uses batteries to achieve peak shifting and valley filling requires manual switching of the power supply mode, resulting in high labor costs for the power supply system; moreover, the more mature lead-acid batteries currently in use also have many disadvantages, such as: lead Acid batteries are bulky, have a large unit energy-to-weight ratio, and poor high-temperature resistance. In high-temperature seasons, air-conditioning and refrigeration support is required, resulting in high construction costs. At the same time, due to the short charge-discharge cycle life of lead-acid batteries, the charge-discharge cycle usually does not exceed 500 times. The working mode of charging and discharging has a short service life and requires frequent replacement, which is not practical
