Meter-reading abnormality analysis method and system of concentrator

Abstract

The invention provides a meter-reading abnormality analysis method and system of a concentrator. The method comprises the steps of S101, acquiring meter-reading data of the concentrator in real time,analyzing the meter-reading data, and judging whether the meter-reading data is abnormal or not; S102, comparing the meter-reading data with fault historical record if the meter-reading data is abnormal, and determining a meter-reading abnormal behavior type of the concentrator; and S103, performing concentrator fault diagnosis to obtain a diagnosis result according to the abnormal behavior type,wherein the diagnosis result comprises a fault reason and a solution scheme. The system is used for implementing the method. By implementing the method, the meter-reading abnormal condition of the concentrator can be conveniently analyzed, a fault point is rapidly locked, and labor and time consumption during handling the meter-reading abnormal condition of the concentrator is reduced.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a method and system for analyzing abnormalities in meter reading by concentrators. Background technique [0002] Concentrator, as a key component of power system meter reading, is the central management device and control device of the remote centralized meter reading system. It is responsible for regularly reading terminal data, system command transmission, data communication and other functions. Inaccurate user electricity consumption data, abnormal and difficult to identify user electricity consumption behavior and other consequences have also brought considerable losses to the grid company, which has always been a headache for the grid company. [0003] Concentrator meter reading abnormality includes many problems such as concentrator not reading meter, meter reading success rate fluctuation, low meter reading efficiency, meter reading data error, operation crash, etc. At...

[0002] The concentrator, as a key component of power system meter reading, is the central management device and control device of the remote centralized meter reading system. It is responsible for regularly reading terminal data, system command transmission, data communication and other functions. The consequences of inaccurate electricity consumption data and the difficulty of identifying abnormal electricity consumption behaviors of users have also brought considerable losses to power grid companies, which have always been a headache for power grid companies

[0003] Concentrator meter reading abnormality includes many problems such as concentrator not reading meter, meter reading success rate fluctuating, meter reading efficiency low, meter reading data error, operation crash, etc. At present, the analysis of concentrator meter reading abnormality mainly adopts on-site inspection by workers Troubleshooting in this way has two obvious disadvantages: (1) Manpower deployment needs to be combined with work plan arrangements, resulting in problems such as untimely troubleshooting and data loss, and consumes manpower and time at the same time; (2) It is difficult to judge the fault location of the concentrator. It is difficult to determine the fault location and key cause of abnormal data collection in a short time
