Embodiment 1
[0025] see figure 1 , the present embodiment discloses a method for quick response to a low-voltage power grid user line power-down fault, including:
[0026] After the energy meter is powered normally, use the built-in energy meter communication module to send the energy meter information to the concentrator in the station area to generate the topology map of the station area; after the concentrator receives the energy meter information, it sends the energy meter information together with its own attribute information to the master station to generate an area topology map.
[0027] After that, the energy meter communication module detects in real time or obtains from the energy meter whether there is a power-off fault. After detecting the fault, it uses the power supply of the backup power supply to generate power-off fault information and transmits it through wired (power line carrier, RS485, etc.) or wireless Send the power failure fault information to the concentrator by ...
Embodiment 2
[0036] see figure 2 , corresponding to the above-mentioned method embodiment, this embodiment discloses a low-voltage power grid user line power-down fault rapid response system, including:
[0037] The electric energy meter is used to send the electric energy meter information to the concentrator of the station area with the built-in electric energy meter communication module to generate the topology map of the station area after the normal power supply; the electric energy meter communication module is also used for real-time detection or acquisition from the electric energy meter. When a power failure occurs, after the failure is detected, use the power supply of the backup power supply to generate power failure fault information and send the power failure failure information to the concentrator through wired or wireless means; wherein, the backup power supply only supplies power to the communication module of the electric energy meter, and The energy storage of the backup...
