Real-time monitoring system for preventing electricity theft for power network

Abstract

The disclosed real-time method to prevent electric larceny comprises: monitoring the transformer substation pass, 10KV distribution lines, special user and public power parameter by a high-voltage electric energy collection terminal; monitoring original parameters by a low-voltage electric energy collection terminal; using a wireless digital communication network to send data to the monitor center to store in database for classification and analysis, then auto drawing load curve and charge curve for different monitor point. This invention has well monitor effect and can alarm by SMS.

Description

Technical field: [0001] The invention relates to a method and device for preventing electricity theft, in particular to a method and a device for managing electricity theft from the power supply side and analyzing and checking electricity theft from the system side. Background technique: [0002] The existing grid anti-theft methods mainly have the following problems: [0003] 1. It mainly protects the 0.4kV user-side metering device, but there are thousands of ways to steal electricity, and it cannot be effectively prevented without using the metering device to steal electricity. Therefore, any technical preventive measures aimed at a single metering device cannot effectively prevent the occurrence of electricity theft; [0004] 2. The traditional anti-stealing inspection mainly relies on manual business census, which has poor timeliness and insufficient census. It is difficult to grasp the operation status of the distribution network in real time, and it is difficult to a...

AI Technical Summary

Problems solved by technology

[0003] 1. It mainly protects the 0.4kV user-side metering device, but there are thousands of methods of stealing electricity, and it is impossible to effectively prevent the electricity theft without using the metering device

Therefore, any technical preventive measures aimed at a single metering device cannot effectively prevent the occurrence of electricity theft;

[0004] 2. Traditional anti-stealing inspections mainly rely on manual business censuses. The timeliness is poor and the census is not in place. It is difficult to grasp the operation status of the distribution network in real time and accurately provide the time, place and related data of the electricity theft. It is difficult to verify

[0005] 3. The existing distribution network line loss analysis system can only give the line loss of the entire feeder, but cannot give the line loss of any branch or node in the feeder. Therefore, the line loss analysis system based on the power automation system can Unable to complete the comprehensive line loss analysis of the entire system alone
