The present application relates to a power supply method and device using a supercapacitor as a backup power supply. The method includes: when operating in the maximum operation mode, detecting whether a minimum operation mode switching instruction sent by the power distribution master station is received, and if so, switching the operation mode from the maximum operation mode to the minimum operation mode according to the minimum operation mode switching instruction , the operating power consumption of the maximum operating mode is greater than the operating power consumption of the minimum operating mode. When operating in the minimum operating mode, detect whether the maximum operating mode switching command sent by the power distribution master station is received, and if so, switch the command according to the maximum operating mode Switch the operating mode from the minimum operating mode to the maximum operating mode, wherein, when operating in the maximum operating mode, select the distribution line for power supply, and when operating in the minimum operating mode, select the backup power supply corresponding to the super capacitor. The method can meet the operation and maintenance requirements when the supercapacitor is used as the backup power supply.
Description
technical field [0001] The present application relates to the field of electric power technology, in particular to a power supply method and device using a supercapacitor as a backup power supply. Background technique [0002] At present, in the selection of the backup power supply of the power distribution terminal, due to the high energy density of the battery, which meets the use requirements of the power distribution terminal when the line fails, the battery is generally used as the backup power supply of the power distribution terminal. However, due to the short service life of the battery, the life span is about two or three years, and the requirements for maintenance are high, resulting in high overall costs. [0003] With the development of power technology, the technology of supercapacitors has become more and more mature. Because supercapacitors do not require maintenance and have a long life, they are a better solution for backup power supply of power distribution...
