Electric power system power outage event report method

Abstract

The invention relates to an electric power system power outage event report method which is used for an electric power system formed by multiple electricity meters, a power concentrator and a power bureau main station. All the electricity meters are connected with the power concentrator in a communication way. The power concentrator is connected with the power bureau main station in a communication way. At least one electricity meter is internally provided with a wireless communication device and a capacitor device for storing electricity. The rechargeable capacitor device and the wireless communication device are additionally arranged on the power line, the capacitor device continuously receives charging of the power line when the power outage event does not occur, the fully charged capacitor device immediately supplies power to the wireless communication device when power outage occurs in the power line of the electricity meter and the wireless communication device is enabled to be charged to maintain wireless communication connection with the power line so that the wireless communication device is enabled to transmit the corresponding power outage event information to the powerconcentrator to be processed, then the power concentrator forwards the information to the power bureau main station and thus the power bureau main station is enabled to send personnel to the power outage area branch for maintenance in time.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a method for reporting power system outage events. Background technique [0002] As the most widely distributed national public infrastructure in the city, the current power system mainly includes several electric meters, power concentrators and the main station of the power bureau. The electric meters in the power system are connected to the power concentrator through the power line, and the power concentrator and the main station of the power bureau are also connected by power line communication. In this way, in the existing power system, the meter can first report the metering data to the power concentrator for processing, and then the power concentrator sends the processed data reported by the meter to the main station of the power bureau. [0003] However, there are still deficiencies in the existing power system: because the communication between the ammeter and the power conc...

Problems solved by technology

[0003] However, there are still deficiencies in the existing power system: because the communication between the ammeter and the power concentrator is realized through the power line, once a power failure occurs on the power line between the ammeter and the power concentrator, the power line will stop working, and the ammeter will also be shut down. The power outage event cannot be reported to the power concentrator in a timely manner with the help of the power line, which will cause the power concentrator to fail to send the power outage event information on the power line to the main station of the power bureau in time, which will be difficult to meet the needs of the main station of the power bureau.
