A system and method for priority identification and reporting of power outage events at the topological level of the terminal power grid

Abstract

The invention relates to a terminal power network topology hierarchical blackout event priority identification and reporting system, comprising a collection master station, a distribution transformermonitoring terminal, a first-level monitoring terminal, a second-level monitoring terminal and a meter box monitoring terminal. The distribution transformer monitoring terminal, the first-level monitoring terminal, the second-level monitoring terminal and the meter box monitoring terminal respectively comprise a control unit and a measuring chip, a power module and a LoRa chip arranged correspondingly to the control unit. A system and method for preferentially identifying and reporting the outage event at the topology level of the terminal power network is based on LoRa internet of things communication technology, When the power failure occurs in the terminal power network, the equipment layer allocates the channel bandwidth resources reasonably through the power failure event priority reporting method, and each terminal has the independent reporting ability, which can quickly inform the main station of the specific link of the fault occurrence, so as to achieve fast and efficient. Inorder to avoid invalid and useless random reporting by the terminals in a rush, the event priority reporting function of the invention reports the terminals at different levels at different time, andthe terminals at the same level avoid reporting randomly, reasonably distribute channel bandwidth resources, and improve the success rate of reporting.

Description

technical field [0001] The invention relates to a system and method for priority identification and reporting of power outage events at the topological level of the terminal power grid. Background technique [0002] When a power failure occurs in the low-voltage end grid, there are many types of faults involved, which are classified according to the topology level, including power failure of the distribution transformer, tripping of the main switch on the low-voltage side of the distribution transformer, tripping of the outlet switch on the low-voltage side of the distribution transformer, tripping of the branch switch of the intermediate branch box, Meter box incoming line switch tripping, etc. When a power outage occurs in the terminal power grid, the monitoring equipment at the corresponding topology level will flock to report the event. Due to the large number of equipment and the limited communication bandwidth, the channel is easily congested, resulting in a lower repo...

Problems solved by technology

When a power failure occurs in the terminal power grid, the monitoring equipment at the corresponding topology level will flock to report the event. Due to the large number of equipment and the limited communication bandwidth, the channel is prone to congestion, resulting in a lower reporting success rate.

In addition, some devices need to report through the relay signal relay, which will further occupy the bandwidth, resulting in a further reduction in the success rate of the report, and ultimately cause the main station to be unable to perceive the abnormalities of each topology level of the terminal power grid in real time, which will bring pressure to the daily operation and maintenance of the power company
