Distribution automation terminal intelligent power supply device and battery evaluation method

Abstract

The invention discloses an intelligent power supply device for a power distribution automation terminal and a battery evaluation method. The device includes an AC input module, a communication module, a display module, an alarm module, a monitoring control module, a battery management module and a power output module. The monitoring The control module is respectively connected with the AC input module, the communication module, the display module, the alarm module, the battery management module, and the power output module, and the power output module is respectively connected with the AC input module and the battery management module; the AC input module, the communication module , alarm module, battery management module and power output module are all externally connected with wiring ports. Through the cooperation of the battery management module and the monitoring and control module, the present invention can realize a powerful battery management function, which is beneficial to the normal operation of the power distribution automation terminal, and through the cooperation of the monitoring and control module and the display module, it can realize the functions of event recording and searching.

Description

technical field [0001] The invention relates to an intelligent power supply device of a distribution automation terminal and a battery evaluation method, belonging to the field of distribution network power supplies. Background technique [0002] Distribution automation terminal equipment (DTU, FTU, remote fault indicator, etc.) is widely used in the construction of distribution network, and is the main technical means for comprehensive monitoring and control of distribution network automation. At present, there are three main power supply methods for distribution automation terminals: 1) Both the operating power and the working power are taken from the external AC power; 2) The operating power and the working power are both taken from the battery; 3) The operating power is taken from the external storage battery. Since the power distribution automation terminal is required to be able to work for a period of time after the 220V AC power is disconnected, the relevant data of...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of the above-mentioned distribution automation terminal power supply system are: the battery management function is relatively single, and the power supply needs to be withdrawn when the battery core capacity is discharged, and the power is completely exhausted, which is not conducive to the normal operation of the distribution automation terminal; most battery management does not have the ability to record events Functions, including events such as internal resistance test, battery activation, and power failure are not recorded
