Intelligent power distribution network

Abstract

The invention discloses an intelligent power distribution network. Each user terminal is provided with a detection module; each user terminal is also provided with a wireless communication chip, so that regional servers can be connected with the user terminals with no wires required; the regional servers collect the working status information data of user home circuits collected by the detection modules of the user terminals through the detection modules, analyze the data, and send circuit abnormal alarms to a cloud server if abnormal fluctuation occurs; each regional server has a region number of a region corresponding to the regional server; each user terminal has a terminal number corresponding to the terminal; the fluctuation condition of the power distribution network of each region can be collected on a large scale; region arrangement intensity can be obtained by means of analysis; large-scale power distribution network abnormality judgment is carried out; terminal arrangement density is obtained through analysis on the basis of the terminal numbers; and small-scale judgment is carried out on the basis of the terminal arrangement density.

Description

technical field [0001] The invention relates to the field of power distribution, in particular to an intelligent distribution network. Background technique [0002] The distribution network can be divided into urban distribution network, rural distribution network and factory distribution network. The structure of the distribution network is huge and complex, and the network structure often changes due to faults or the opening and closing of switches during load transfer operations, so it is difficult to judge in advance where the distribution network is operating abnormally, and it cannot be maintained in time, and the existing The method of detecting abnormal locations can only find out where maintenance is required after a problem actually occurs. However, when such problems occur, large-scale power outages often occur without warning, which will cause unnecessary In addition, after a single-phase ground fault occurs in the distribution network, in the traditional fault ...

The structure of the distribution network is huge and complex, and the network structure often changes due to faults or the opening and closing of switches during load transfer operations, so it is difficult to judge in advance where the distribution network is operating abnormally, and it cannot be maintained in time, and the existing The method of detecting abnormal locations can only find out where maintenance is required after a problem actually occurs. However, when such problems occur, large-scale power outages often occur without warning, which will cause unnecessary In addition, after a single-phase ground fault occurs in the distribution network, in the traditional fault location process, the distribution network generally adopts the method of switching off the power line by line to determine the fault line. After the fault line is selected, the work is dispatched Personnel go to the scene to find the fault location along the line, and then eliminate the fault. Due to manual intervention, this method requires a relatively long time for positioning, and it is difficult to adapt to people's new requirements for the automation level of the distribution network. Moreover, the scope of this initial positioning is vague. As a result, the staff need more time to narrow down the positioning range, and cannot quickly find the priority maintenance area, which causes a waste of time, and this waste of time is likely to aggravate the fault, and this fault may cause excessive voltage, burn out the equipment, and even cause phase-to-phase short circuit and expand the accident
