Rapid fault detection and power recovery system based on rural power network, and concentrator detection method thereof

Abstract

The invention relates to a rapid fault detection and power recovery system based on a rural power network, and a concentrator detection method thereof. The rapid fault detection and power recovery system comprises an automatic metering system, a communication interface and a terminal and further comprises an alarm module; processed data comes from the automatic metering system and a marketing management system; the processed data is fed back to a low-voltage comprehensive application management system; the terminal comprises a distribution transform monitoring terminal, a concentrator and a metering unit group; the minimum detection voltage of a voltage detection module of the concentrator is 10V; both the distribution transform monitoring terminal and the concentrator are each provided with a wireless communication module communicated with the automatic metering system, and periodically perform data communication with the automatic metering system; the heartbeat cycle of the distribution transform monitoring terminal is 15 m; and the heartbeat cycle of the concentrator is 5 m. According to the rapid fault detection and power recovery system based on the rural power network, and the concentrator detection method thereof disclosed by the invention, the alarm precision is finely divided into four kinds by upgrading software in the existing concentrator, completing the interface of the automatic metering system and shortening the data interaction cycle of the concentrator and an ammeter; different maintainers can be dispatched easily; and thus, active and rapid first-aid repair is realized.

Description

technical field [0001] The invention relates to the technical field of electric power information communication, in particular to a system based on rapid fault detection and power restoration of rural power grids, and belongs to the technical field of electric power equipment. Background technique [0002] Low-voltage distribution network generally refers to the general name of the power line from the main circuit switch on the low-voltage side of the distribution transformer (rated voltage is 400v) to the electric energy metering device of the customer. It is the lowest voltage level, the largest number, and the most operating environment in the power network. The part that is harsh and most directly connected with residents' electricity consumption. [0003] In the routine low-voltage power supply and emergency repair tasks of rural power grids, for unplanned power outages, the user must call 95598 for repairs before scheduling rush repairs. There are too many intermediate...

However, even if the collection cycle is only shortened for some meters on the branch lines below the station area, for example, the collection cycle is shortened to 15 minutes, due to the consideration that the shortened collection cycle will cause a large amount of data traffic charges for the concentrator and the master station, and will affect the existing There are consequences of interference caused by the stability of the metering automation system collection, so it is not advisable to realize the power failure alarm of the lines and equipment below the station area by only modifying the server-side program
