Power grid abnormal data prediction statistical system

Abstract

The invention discloses a power grid abnormal data prediction statistical system, and relates to the technical field of power grids. The system comprises a power utilization information acquisition system for performing line loss statistics, line loss analysis and line loss index assessment on a transformer area; a use end for checking power grid data; a collection module for collecting and arranging different types of data of the transformer area; a monitoring module for monitoring various data of the transformer area; and an analysis module for analyzing the various data of the transformer area. Various data can be collected and recorded, various abnormal types and abnormal phase types of an examination meter, a photovoltaic meter and a user meter are screened, reasons of abnormal fluctuation of electric quantity are analyzed, meanwhile, a clear direction is provided for line loss treatment work, various abnormal problems of each unit are counted in advance one day before line loss calculation, data summarization is formed and early warning is carried out, so that a transformer area manager can be conveniently guided to carry out line loss elimination work in advance, and the transformer area line loss rate is reduced.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a power grid abnormal data prediction and statistics system. Background technique [0002] Line loss management in the station area is an important measure to increase revenue, reduce costs and increase efficiency, and is also an important yardstick for evaluating the level of management. State Grid Shanxi Electric Power Company has promoted the application of the power consumption information collection system since 2010, and the power consumption information collection system The line loss management function has been realized, and the line loss statistics, line loss analysis and line loss index assessment of the station area have been realized. However, with the improvement of the line loss management level in recent years, the requirement for leaner line loss management is getting higher and higher , the original "one-size-fits-all" evaluation method of line loss rate is ...

[0002] Line loss management in the station area is an important measure to increase revenue, reduce costs and increase efficiency, and is also an important yardstick for evaluating the level of management. State Grid Shanxi Electric Power Company has promoted the application of the power consumption information collection system since 2010, and the power consumption information collection system The line loss management function has been realized, and the line loss statistics, line loss analysis and line loss index assessment of the station area have been realized. However, with the improvement of the line loss management level in recent years, the requirement for leaner line loss management is getting higher and higher , the original "one-size-fits-all" evaluation method of line loss rate is relatively extensive. At the same time, the existing line loss rate calculation is mainly based on a single supply and sale of electricity data, and has not fully considered factors such as complex physical topology, diverse sources of anomalies, and regional environmental differences. , there is still a certain gap with the requirements of lean management of line loss in the Taiwan area

[0003] The existing line loss rate in the station area remains high, and there are many factors that affect the line loss in the station area, such as copying, verification, and receipt management in business work, serious omissions and omissions, illegal use of electricity by users, and electricity theft etc., without the lean management of line loss in the station area, the cause of the line loss cannot be analyzed in time, and the line loss elimination work is carried out, which increases the difficulty of line loss management in the station area. The existing line loss management in the station area cannot be based on Data analysis shows that the power grid is abnormal, and it takes a lot of time to deal with the abnormality of the power grid, which makes the line loss rate of the station area larger
